Duplicacy encryption. Lock-Free Deduplication.
Duplicacy encryption I sort of suspect it is impossible to make self-signed certificate trusted on windows (edge keeps nagging me about my self-signed ones every time), but if you import your Root Ca into Trusted System Certificates zone all SYNOPSIS: duplicacy restore - Restore the repository to a previously saved snapshot USAGE: duplicacy restore [command options] [--] [pattern] OPTIONS: -r <revision> the revision number of the snapshot (required) -hash detect file differences by hash (rather than size and timestamp) -overwrite overwrite existing files in the repository -delete delete files not in the snapshot alexmbp:~ alex$ duplicacy benchmark --storage minio Storage set to minio://us-east-1@tuchka. DUPLICACY_BACKUP_OPTIONS: options passed to duplicacy backup when a backup is performed. Hello everyone, I've been doing research over the last few days into software that would allow me to upload AND encrypt my main computer hard drive (as well as an external 6 terabyte hard drive) into my unlimited storage Google Drive account. Duplicacy will attempt to retrieve in three ways the storage password and the storage-specific access tokens/keys. This is a very basic stuff. The storage was added using add -copy. 14M byte random data in memory Writing random data to local disk Wrote 244. Following the instructions and doing the verify afterwards (duplicacy info ), I only get “The storage is encrypted with a password”. I need it to Hello, I have a serious restore problem with duplicacy. benchmark. Duplicacy is built upon a new idea, lock-free duplication. With just a few clicks, you can effortlessly set up backup I’m new to Duplicacy and was reading through the docs trying to understand the use case of RSA encryption. So no point in more that ~40 characters for the encryption Default Encryption: Disable (using Duplicacy’s encryption) Lifecycle Settings Keep only the last version of the file Object Lock Disabled but unsure what else I should be doing here without negatively impacting Duplicacy. Therefore, to add encryption — actual data in all chunks need to get replaced with encrypted version. Once everything is good – delete original storage. I’m getting the following error: Please advise. Does this suggest then that a best Duplicate practice would be to put as much data into a single B2 bucket to leverage as much de-dup as possible assuming that no individual source needs to Duplicacy is a web-based GUI client for Windows, macOS X and Linux that offers the ability to backup your files to a variety of cloud storages with client-side encryption and deduplication options. Duplicacy follows first-level symlinks, and therefore you can easily add multiple locations (e. Quick overview NAME: duplicacy benchmark - Run a set of benchmarks to test download and upload speeds USAGE: duplicacy benchmark [command options] OPTIONS: -file-size <size> the size When I set up my backend storage with Google Drive I downloaded the gcd-token. So if I have performed a backup on one computer and put all backup files on an external drive, what happens if my original computer (where Duplicacy is installed) is no longer available? In other words, if I buy a brand new computer, can I still restore all of the files that are on the external drive or did I make a mistake by not backing up the “temporary directory” “log I’ve been reading around about RSA encryption and the ability to back up several different sources to the same bucket securely without needing to share the decryption key. Every time I start Duplicacy Web Edition, it asks for the encryption password (in the web UI). As soon as the storage configuration is done, Duplicacy will first determine if the storage has already been initialized. But does Duplicacy offer any kind of protection against a Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication Download. The password command decrypts the storage configuration file (config) using the old password, and re-encrypts the file using a new password. The password you enter for the storage is itself encrypted and stored in the duplicacy. pem -copy [existing storage] -repository D:/[redacted] [new storage] [rep id] b2://[new bucket for RSA] But I’m getting a kind of looping when I run the Arq vs Duplicacy Web Edition Encryption . However, from personal experience, I'd argue that Duplicacy is better backup software. While I understand that it adds an extra layer of protection (in that the private key can be kept entirely separate from the backup) I cannot seem to understand any other real use case for this behaviour. 0 on a Linux x86-64 system. Hello! I am using the duplicacy CLI. It does not change all the encryption keys used to encrypt and decrypt chunk files, snapshot files, etc. With just a few clicks, you can effortlessly set up backup I have Duplicacy configured for two storage locations : Dropbox and Microsoft Azure. home. I don’t see the public key as described and nothing is put in the preference file. With just a few clicks, you can effortlessly set up backup Storage password in duplicacy protects encryption keys stored in the config file that are used to encrypt your data in chunks, regardless of where your duplicacy datastore is stored. I have two unencrypted, bit-identical storages with erasure coding – call them A and B I’d like to (1) encrypt them and (2) change the erasure coding ratio My plan is: Remove/reset storage B and re-init as encrypted and copy-compatible with A, with the new erasure coding Copy from A to B Verify B works with a test restore Once verified, repeat in So I’ve been experimenting heavily with putting Duplicacy backups on Amazon s3 and transitioning them to s3 Glacier Deep Archive which is extremely affordable. From then on, the encrypted password is used. The benchmark command is used to test the I have a local and remote storage. My backup/prune commands look like this (encryption/password related stuff omitted for brevity): duplicacy-wrapper backup duplicacy-wrapper prune -a -keep 0:365 -keep 30:30 -keep 7:7 -keep 1:1 duplicacy-wrapper prune -a -exclusive duplicacy-wrapper copy -from default -to b2 Keep credentials to the storage and duplicacy encryption password somewhere other than your PC and unraid server, in case both succumb to fire or what not. By default: -threads 4 -stats. It keeps saying the old password is invalid even though I’m certain it’s the right one, as I use a password manager. My current ISP max upload speed is about 10Mbps. Repository ID and Encryption. If enabling that to will dedup still work? Regards I’m trying to create a storage with RSA encryption copying from another existing and encrypted storage (without RSA), both in B2. I was wondering the specifics on encryption being used during the local encryption. I’m attempting to backup from Windows (v2. New feature: RSA encryption UserX can now create an RSA encrypted backup with a public key and can restore or check with the Hey guys, I installed duplicacy-web yesterday to test it out. cybersecsolutions 3 May 2022 04:18 #3.

Duplicacy offers features such as versioning, encryption, and cross-platform compatibility, making it a versatile choice for data backup needs. Once added, new encrypted backups run successfully via the Web Edition using the CLI RSA key encrypted storage and CLI Backup IDs. info isn’t supposed to tell you all the details about a storage – it can only tell if the storage is encrypted or not. 0. As per the documentation, this option tells duplicacy to copy the IDKey, ChunkKey and FileKey to the new storage from the old one to the Hello, Obviously, Duplicacy can protect against a ransomware attack where local files are encrypted and then a scheduled backup is made (which would now contain all of the newly encrypted files at a new backup revision) Here is what i do not understand. I also checked the box “make it compatible with” for the Google Drive storage, after the SSH storage was already created. 04 VM. I'll be explicit and say that a simple GUI is something that I used Duplicacy to create an encrypted local backup of my 1TB of files. json file. 14M bytes I wanted to store my encryption key in my password manager, and paste it into Duplicacy for backup/resto While setting up a new backup set targeting S3, I was unable to paste the encryption password into the GUI prompt. The problem is that I do not remember the encryption password I had setup for this test data set, so I cannot init the storage space. To initialize a new encrypted storage with the RSA encryption enabled, run the following command: $ duplicacy init -e -key public. With just a few clicks, you can effortlessly set up backup Yes, the password is used to generate the master key, which in turn is used to encrypt/decrypt the config file stored in the storage. Later you may decide to move your Duplicacy datastore to e. This appears to collect all of the user files from the shared folders plus other system-related bits and pieces that may or may not be of any use as part of a restore. The Usually the web GUI can retrieve the master password from keychain/keyring, or from the environment variable DWE_PASSWORD. However, this a headless box, and I’m running Duplicacy automatically on startup. This is what works as expected: I configured a new encrypted storage “N” (with the same password “P” as all my other storages). Now, the day after, I want to do a Copy command to copy that local backup to my Backblaze B2 cloud storage. I now wanted to do a restore test via the duplicacy CLI version. Ok awesome i left it on 6, Thank you for clarifying. pem With rclone, the most common choice is to simply mirror/sync Duplicacy’s backup directory to another storage destination.

Are these files being encrypted Prior to being sent to Microsoft Azure? any way to validate in the CLI? I am using Mac web edition. If you are backing up a hard drive (and not a SSD), it is recommended to use -threads 1 -stats instead (see here for more details). However as it says in the title, I’m a bit puzzled as to why I am able to perform file restorations without ever being queried to input the password for a storage When trying to run a check with -chunks I’m getting more than 100 warnings for either the chunk can’t be found, or authentication failed, or doesn’t seem to be encrypted. It The benchmark command is used to test the upload and download speeds for a specific storage and disk access speeds for your repositories. I have encryption enabled. After successfully getting unencrypted backups and restores to work, I moved on to encrypted backups. It does not change all the encryption keys used to encrypt and decrypt chunk 3: 3223: 7 September 2020 Benchmark command details. Those keys are pretty strong though, and I wonder if it would be possible to encrypt the data associated with each snapshot ID with a seperate key. Solution: use a password Duplicacy works as follows: all files selected for backup are combined into a long sausage, which is then shredded into chunks; each chunk is encrypted, given a name according to its hash, and uploaded to chunks folder on the storage. Console said The storage has not been Remember that the weak point of all encryption is the password. Absolutely. RSA key encrypted storage initialized with the Duplicacy CLI and having existing CLI backup revisions can be added in the Dupicacy Web Edition. In addition, Duplicacy also supports local disks and Duplicacy is the only cloud backup tool that allows multiple computers to back up to the same cloud storage, taking advantage of cross-computer deduplication whenever possible, without direct communication among them. So don’t keep the two on the same system as the data, as it defeats the point. I created an SSH storage and a Google Drive storage. Then I did a backup. You can’t delete or rename a backup/snasphot id with the Web GUI or CLI. From my limited understand of encryption in Duplicacy, the master password simply decrypts the config file on the storage, and can certainly be changed.

It has by far the best support for cloud backends, is lock-free, and supports deduplication, compression, and encryption. Forgot my encryption key, I know big goof on me. Support. Duplicacy with RSA Encryption Initialization To initialize a new encrypted storage with the RSA encryption enabled, run the following command: $ duplicacy init -e -key public. I have initialized backup storage for repository “/” on a local disk mounted at “/backup” and excluded that directory from the backup. Duplicacy with RSA Encryption Initialization. Because this is just a test, I could re-create the The standard encryption is symmetric – you need to the same password to backup and to restore. On Mac OS X it is Keychain, and on Linux it is gnome-keyring. Yes, duplicacy -d list is the right way. Running the backup says it will take about 9 days to backup the 5GB worth Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication Download. I could keep them permanently mounted on the server where duplicacy runs but that defeats the purpose of network isolation (e. Alternatively, you can use paypal to purchase licenses. 10 CLI. It is designed to simplify the backup process while optimizing storage space by eliminating redundant data. This page will ask for a password that is used to store all the passwords and credentials that the application uses. The corresponding RSA private key uses an empty password. But this is completely unnecessary, because duplicacy supports encryption itself. (unfortunately I don’t have the storage creation log, I used command line) But the info -d only tells me that “The storage is encrypted with a I’ve setup an iDrive e2 bucket (no versioning or encryption enabled) and configured that in storage with 5:2 Erasure Coding enabled.

On Windows the Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication Download. The OpenSSL application requires input of a passphrase to successfully generate a private I am just trying out RSA encrytion as described in New feature: RSA encryption , but doesn’t seem to work for me. The “-e” option indicates that this data will be encrypted with a password, so enter (and re-enter to confirm) the desired encryption password when prompted by the duplicacy init command. All the storages are bit-identical, using the same RSA key for encryption. Now I’m wondering if by using Erasure Coding deduplication still works? Is dedup done before encrypting? I see there is an extra option to use RSA Encryption. The private key can be encrypted by a passphrase. I’m running this command to add the new storage: duplicacy add -encrypt -key public. The idea of public-private key encryption is that you keep the private key somewhere safe (like in a password manager), and only have the public key on the system that’s used to encrypt. Also, are other asymmetric encryption methods supported as well, eg. The main benefit: Support for separate roles that can back up to and restore from the same storage (and take advantage of deduplication) and yet separately and independently revocable; Example: user A can backup and restore, user B can only backup, Duplicacy uses filesystem api to stat, open, and read files. Someone on reddit brought up an idea of supporting multiple separate encryption/keys in a backup tool. I think the master keys are 256 bit? If so then you can at least says that there is no point in a >256 bit password. If a secret vault service is available, Duplicacy will store passwords/keys entered by the user in such a secret vault and later retrieve them when needed. I am curious to know if it is recommended, or discouraged, to activate the encryption option if my intent is to Isn’t the storage encrypted already by using the storage password? RSA Encryption use case. The first step will be to initialize the duplicacy backups at the directory to be backed up (repository in duplicacy terminology). It feels pointless, since Duplicacy already encrypted it when creating the local backup. I configured a new backup “N”. I will transition my Linux OS disks to ZFS so that Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication Download. I would continue using duplicacy encryption for consistency — maybe you’ll want to move duplicacy datastore elsewhere in the future. Yes. I was fully expecting that it would read and interpret the content of the file and store it encrypted inside the container (and indeed within the container there appears Performance / CPU utilization. If you add to a new repository, a storage location that has already been initialised by another repository using RSA encryption, does that mean you don’t need to add the -key command to the second repository?. I’m having trouble with the encryption password on a headless Linux box (an LXC container on Proxmox, technically). I’ve reinstalled another instance of Duplicacy GUI and added Google token, when at ‘Configure the storage’ it asks for a unique Duplicacy allows you to back up your files to multiple cloud storages using client-side encryption and the highest levels of deduplication. Can I get a refund if I find out Duplicacy isn't the right tool for me. The snapshot is encrypted by AES-GCM too, using an encrypt key that is the The password you enter for the storage is itself encrypted and stored in the duplicacy. This is the one that is usually stored in a keychain/keyring (or similar) if possible. Any ideas where to begin troubleshooting Duplicacy vs Duplicati. I wanted to store my encryption key in my password manager, and paste it into Duplicacy for backup/restore. if the server gets infected with an encrypting virus it would encrypt the backups as well) Thanks!

The Administration Password is the password that you can set so that a user wanting to access any page served by duplicacy init - Initialize the storage if necessary and the current directory as the repository. However some of these are failing to run as the storage (encryption) password is being asked for. Since duplicacy encrypts its data anyway it’s kind of redundant, but storj is always end-to-end encrypted, so you have to pick an encryption passphrase. In short, choose a good encryption password to use with your setup above and you will be safe. Chunks are immutable, so this cannot be done. Share instructions of how to use Duplicacy. If the password is weak it can be obtained by brute force and other methods, although this is difficult to do with a backup made on chunks like Duplicacy. With just a few clicks, you can effortlessly set up backup Chunks can be copied without encryption/decryption between two compatible storages, and that is the only mode supported so that is why it won't copy if storages aren't compatible. You’ll have to do it from the storage side. Good evening everyone, I’m having some trouble to get duplicacy to work after having to reinstall Windows. ) How-to. saspus 6 December 2024 16:32 #4. What Does Encryption Actually Encrypt? saspus 18 August 2021 20:44 #3.

With just a few clicks, you can effortlessly set up backup I’ve been running Duplicacy GUI via Docker on my NAS - my drive failed and I lost everything, fortunately I have encrypted backups of my files on Google Drive (including the previous Duplicacy config - I backed up my Docker apps folder). Duplicacy with RSA Encrypti So that other people may review it, or comment on it like i did here, maybe. com, between your web browser and our license server, between our license server and Stripe. I understand that’s used to decrypt the other passwords. I currently have a local server (NAS) that has many directories split across several repositories, that are all encrypted with the same password and all backup to the same offsite storage (B2). I’ve followed a few other users who had similar issues and was presented with the fix of deleting the key for “encryption_data” in the duplicacy. Duplicacy comes with a newly designed web-based GUI that is not only artistically appealing but also functionally powerful. If you use s3 storj integration, then encryption happens on storj gateway. I’ve added duplicacy to PATH and tried to duplicacy list, was asked the API Access Key, passphrase and password. Lock-Free Deduplication. I’ve used Duplicacy Web as the primary backup tool for the single volume on my DS920+ for over a year. On top of that, it’s done in a way that’s simple to understand. I’m pretty new to using linux but I’m using jq Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication Download. Dropbox Setup asks for password for encryption. What sorts of issues did you have with Arq? There is also bit-identical, in which case even encryption keys are identical, and you can copy repositories using third party copy tools like rclone, without needing to decrypt/re-encrypt data, as would be Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication Download. 33M/s Split 244. Recently I started evaluating if the Duplicacy CLI (linux binary) can be an option to backup my Synology NAS to Backblaze B2 as the Cloud Sync Synology implementation for B2 has so many flaws (mainly it doesn't encrypt file names, it is not block based in any way so it reuploads whole files even if Unsupported encryption version 1. Encrypting again already encrypted data provides little value, only extra chores managing more keys. Microsoft Azure does NOT, only asks for access key and storage locations. I’ve defaulted to the “kitchen sink” approach and set up the entire volume as the repository. To get even better performance, increase duplicacy chunk size. The CLI (command-line interface) Linux version is free for personal use but requires a paid license for commercial users. Thus if you got the <snapshot id> wrong, you can correct it by editing the . Upon creating the bucket in Backblaze, I was presented with an option for server-side encryption. mapped drives) to your backup set. And now I want to use the CLI in a different mac machine to manage it (prune, check, etc) How do I init this storage? I’ve tried duplicacy init test gcd://Backup/Duplicacy - key ‘abc’ → RSA encryption can’t be enabled with an unencrypted storage duplicacy init test gcd://Backup First, thanks for writing Duplicacy. With just a few clicks, you can effortlessly set up backup I think I’m doing something wrong I created a new storage encrypted with RSA and transferred the contents of the old storage (also encrypted) to it. pugglewuggle 28 January 2021 20:30 #1. This section explains Just as an FYI, if your local NAS has support for per-file encrypted storage, it’d probably be much more efficient in combination with rsync than doing Duplicacy -> local NAS -> rsync -> off-site NAS because all of your music files are already compressed Duplicacy will be spending time compressing data that doesn’t really need it. 1. gchen 6 April 2020 19:47 #2. When using S3 gateway, the gateway has the Duplicacy with RSA Encryption Initialization. However, duplicacy implemented CAS on top of existing checksummed storage api and hence in my opinion it’s a waste of time to run any check but the basic one: wanting to validate chunk content means you don’t trust your storage. The use case I’m thinking of is a shared storage used by many clients that are from different organisations but Duplicacy already provides encryption. json file from Google and put it in a temporary directory on my NAS. Chunks would need to be encrypted with a common key as is currently the case as these would be shared between all revisions across all snapshot IDs. SYNOPSIS: duplicacy set - Change the options for the default or specified storage USAGE: duplicacy set [command options] OPTIONS: -encrypt, e[=true] encrypt the storage with a password -no-backup[=true] backup to this storage is prohibited -no-restore[=true] restore from this storage is prohibited -no-save-password[=true] don't save password or access keys to By default, -encrypt if BACKUP_ENCRYPTION_KEY is not empty. I forgot to add the -key option, but it is a location that has already been initialised by another repository (and so I had to use the same encryption Duplicacy is a powerful cloud backup tool that provides efficient and secure data backup and deduplication capabilities. I read the duplicacy add command instructions carefully and did a duplicacy add -e -copy default --bit-identical to add the b2 storage. pem Please describe what actually happens (the wrong behaviour): Get the message: unrecognized public Settings for Duplicacy Web Edition. If you are the only user and not in a multi-user backup environment is there any real benefit of using the RSA encryption over just using the storage password? Example, when creating a new storage in The minio storage backend allows Duplicacy to back up to any public or private S3-compatible storage. Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication Download. , more encryption keys to I see that Duplicacy uses AES for encryption. I recently set up Duplicacy to perform backups to my Microsoft OneDrive storage backend using a key pair generated with OpenSSL. The RSA encryption key can’t be changed. I am very interested in leveraging it for its high backup efficiency properties to be able to keep regular ol’ files backed up well for anything that is not resident on ZFS pools which already provide robust and efficient replication via zfs recv/send. Hello, Obviously, Duplicacy can protect against a ransomware attack where local files are encrypted and then a scheduled backup is made (which would now contain all of the newly encrypted files at a new backup revision) - the simple answer being to restore a previous version from a backup destination. pem repository_id storage_url The RSA encryption can be only enabled if the storage is encrypted (by the -e option). duplicacy However, I am having some trouble understanding how encryption works when using a S3 service, and would appreciate some help wrapping my head around it. This is my first time running -chunks in more than three years of running backups. Our paper explaining the inner workings of Duplicacy has been accepted by IEEE Transactions on Cloud Computing and will appear in a future issue this year. The final draft version is available here for those who don't have IEEE subscriptions. This should not affect the existing backups. Let’s say my B2 storage is connected to Duplicacy with only keys with “add Please describe what you are doing to trigger the bug: I am trying to set up a repository using the new RSA encryption feature duplicacy init -e -key public. If Using Duplicacy on Unraid in a docker container. Do I need to use the same password on all repositories I am backing up to that storage in order to effectively de-duplicate across repositories and hosts? So whenever you “initialize” a storage that has already been initialized, duplicacy will just silently use the existing Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication Download. 9 GUI) to via SFTP to a Linux-based storage created with v2. 04s: 5772. On Windows the passwords/keys are encrypted and decrypted by the Data Protection API, and encrypted passwords/keys are stored in the file . (Posts in this category will be wikis by default. Instead, it is supplied to the hasher right after the hasher has just been initialized. When using gateway however - gateway has encryption keys by necessity, so this is no longer end to end encrypted. Hello 🙂 Would like to ask a couple of questions: Is it possible to initialize a new encrypted storage with the RSA encryption using Duplicacy Web Edition? Which criteria two storages need to met in order to be copy compatible? Thanks in advance! I understand that duplicacy functions as a file level backup tool. duplicacy init [command options] <snapshot id> <storage url> -encrypt, -e encrypt the storage Thanks to Lock-Free Deduplication, Duplicacy work smoothly with most cloud storage services without compromising any essential features required of a state-of-the-art backup tool. bfcaazr fdzwzn tdhq dsbb ayfumwfb rloev vjsffa jucaf pzlaxt wpm
