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 I am using duplicacy to do daily backups of a NAS to Backblaze B2. Therefore, to add encryption — actual data in all chunks need to get replaced with encrypted version. Click here for a list of related forum topics. 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 From the research that I did and articles that I've read, Duplicacy seems like the winner in my book. 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 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, When using gateway however - gateway has encryption keys by necessity, so this is no longer end to end encrypted. I set up Duplicacy quite a while ago, and don’t remember; but is the Encryption Password the same as the Master Password described in Duplicacy User Duplicacy backs up your files to many cloud storages with client-side encryption and the highest level of deduplication Download. I successfully tested that by creating another Storage ID for the same location. I need it to The benchmark command is used to test the upload and download speeds for a specific storage and disk access speeds for your repositories. It has by far the best support for cloud backends, is lock-free, and supports deduplication, compression, and encryption. 1. 5 cent you will then be presented with the encryption dialog: If the bucket has not been used as a Duplicacy backend before, the dialog will allow you to optionally choose a storage password twice that will be used to This is the user guide for Duplicacy Web Edition. Cheers. Local disk Storage URL: /path/to/storage (on Linux or Mac OS X) C:\path\to\storage (on Windows) SFTP Storage URL: s 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 First, thanks for writing Duplicacy. Duplicacy also supports optional asymmetric encryption with RSA keys for ultimate security – the key that is used for backup cannot be used to restore, you need separate key for restore that does not need to be present on the machines doing the backup. /duplicacy init -encrypt 1 b2://SLAVESERVER followed by I’ve setup an iDrive e2 bucket (no versioning or encryption enabled) and configured that in storage with 5:2 Erasure Coding enabled. 8. cybersecsolutions 3 May 2022 04:18 #3. 14M byte random data in memory Writing random data to local disk Wrote 244. I didn’t come to realize my backups were failing at all until a month after they stopped working. pem 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?. Later you may decide to move your Duplicacy datastore to e. I have several repositories all backing up to the same storages, using distinct (across repositories) but consistent (across storages) snapshot IDs. To initialize a new encrypted storage with the RSA encryption enabled, run the following command: $ duplicacy init -e -key public. Every time I start Duplicacy Web Edition, it asks for the encryption password (in the web UI). The CLI (command-line interface) Linux version is free for personal use but requires a paid license for commercial users. The corresponding RSA private key uses an empty password. You can also make it ransomware-proof by carefully crafting the B2 credentials to only allow upload and disallow change or delete, effectively making your backup immutable. 1) **Password**: “Configuration file” or “Encryption” password. Zhup 13 June 2017 08:48 #1. Encryption - length of the password . ECDSA? F. pem repository_id storage_url The RSA encryption can be only enabled if the storage is encrypted (by the -e option). But I ran into an interesting problem today. saspus. The storage password is used to encrypt the config file, and snapshot files are encrypted by a key derived from the snapshot ID and the revision number. I would like to make sure of my understanding So whenever you “initialize” a storage that has already been initialized, duplicacy will just silently use the existing storage configuration. Thank you Duplicacy will attempt to retrieve in three ways the storage password and the storage-specific access tokens/keys. Dropbox Setup asks for password for encryption. Or rsync to do the rolling hash magic. I would continue using duplicacy encryption for consistency — maybe you’ll want to move duplicacy datastore elsewhere in the future. Following the instructions and doing the verify afterwards (duplicacy info ), I only get “The storage is encrypted with a password”. Repository ID and Encryption. Lock-Free Deduplication. Then I did a backup. without encryption), but you can simply try it out. The password command decrypts the storage configuration file (config) using the old password, and re-encrypts the file using a new password. Quick overview USAGE: duplicacy password [command options] OPTIONS: -storage <storage name> change the password used to access I realize this is a basic question , but I have searched and could not find a definitive answer. andrew. For graphs in duplicacy — I don’t really use their UI. The user guide for the old GUI version can be found here. If encryption is enabled, you will be prompted to enter a storage password. I recently set up Duplicacy to perform backups to my Microsoft OneDrive storage backend using a key pair generated with OpenSSL. 2. It's well priced, (Web Edition is $20), light, contains encryption, has moderate to fast upload/download speeds, and more importantly, is good at picking up where it left off in the upload/encryption process. After successfully getting unencrypted backups and restores to work, I moved on to encrypted backups. (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 see that Duplicacy uses AES for encryption. json file. 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. Asymmetric encryption. It keeps saying the old password is invalid even though I’m certain it’s the right one, as I use a password manager. pem repository_id storage_url The public. I configured a new backup “N”. pem Please describe what actually happens (the wrong behaviour): Get the message: unrecognized public I’m trying to use Duplicacy to backup the entire file system on a fairly bare-bones Ubuntu 18. Q2: How robust is the included encryption? Are there backdoors? Duplicati is a free, open-source backup solution that offers zero-trust, fully encrypted backups for your data. I was experimenting, and now i’m ready to run with it. 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 So the RSA encryption only works when there is a storage password? If you provide a RSA key, but no storage password, it doesn’t display the message “RSA encryption is enabled” and I can restore without the key. pem is a pretty standard gpg --export --armor key_id > public. It sounds like this should be done at storage initialization, but I don’t remember the option and I definitely didn’t manually set anything. 41s: 600. What is the benefit of using RSA vs standard I’m learning how to use Duplicacy CLI and having success with my testing. Hi gchen, May I know what kind of encryption does Duplicacy uses? Thank you! gchen 12 December 2016 18:23 #2. When using S3 gateway, the gateway has the Hello friends! New user here and I love how straightforward and effective this software is so far; backups are working fine and the size savings as well as the raw speed of chunk backups are a huge bonus. I don’t see the public key as described and nothing is put in the preference file. 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. If you start using a new machine, then you’ll need to re-enter the storage encryption password. uldmbfl prgu fscpwt suhyc dqco jqzg agpoultk zby ykm scv
