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. For this, I just run the copy command. 100 daily backups would result in you storing one main copy of data and incremental changes after that only. To decrypt such a chunk, Duplicacy will first recover the key from the RSA encrypted key (which requires the RSA private key), and then use that key to decrypt the chunk content. 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. I tend to keep a Backup of my Config for the Backups (snoop dog meme here)… Duplicacy comes with a newly designed web-based GUI that is not only artistically appealing but also functionally powerful. . txt, for output of working example, Solution.

May 27, 2024 · when backing up to storj via duplicacy, am I correct that duplicacy will encrypt the data at the client side before sending it. Now, the day after, I want to do a Copy command to copy that local backup to my Backblaze B2 cloud storage. (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 password” for the new Aug 16, 2020 · 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 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 password). So as my Synology has an Intel Quad Core my hunch is it is using only one core and the process could maybe be accelerated a lot when it would use all or at least 3 cores. To initialize a new encrypted storage with the RSA encryption enabled, run the following command: $ duplicacy init -e -key public. I understand that’s used to decrypt the other passwords. The corresponding RSA private key uses an empty password. saspus. I tested the restore with my duplicacy-web (saspus) docker on unraid and it worked as expected. 2. If it has not, it will present this dialog to you: Jul 24, 2019 · When you initially add the storage, it asks you for the password used for encryption. 14M bytes in 0.
