Not to be confused with Duplicati [1] or Duplicacy [2]. There are too many backup programs whose names start with 'Duplic'. [1] https://www.duplicati.com/ [2] https://duplicacy.com/. - Source: Hacker News / 5 months ago

I have been having great luck with incremental backups with the very similar named Duplicacy https://duplicacy.com/. - Source: Hacker News / 5 months ago

My recommendation would be Duplicacy [0]. Code is also on GitHub [1]. It has a paid GUI version, $20 for the first year and $5 for subsequent years with discounts for multiple machines [2]. At least once they've run a promotion for a very cheap lifetime license. Use it just from the CLI is free. My setup is pretty simple, Syncthing and Duplicacy (GUI version) run in a docker container on my home server. Everything... - Source: Hacker News / 5 months ago

Having all your data in one place isn't wise though, so I am planning on storing encrypted backups on Dropbox and Backblaze B2 using Duplicity so that I am following the 3-2-1 backup rule. - Source: dev.to / 9 months ago

I tried a bunch of different ways but ultimately settled on Duplicacy [0]. It runs inside a Docker container and backs up both my data as well as configurations like my docker compose file and smb.conf. Off site storage was Backblaze B2, but I moved to Hetzner. Likely will move back just because B2 is cheaper and a bit faster for my region. Another layer of backup I do is use Duplicacy to backup to a portable hard... - Source: Hacker News / about 1 year ago

Dar is the only tool I know of that supports incremental backups to untrusted remote storage. All the remote sees are giant encrypted blobs. Source: about 1 year ago

DAR is a linux tool that does incremental updates after a snapshot: http://dar.linux.free.fr/. Source: about 1 year ago

I have also used dar ( http://dar.linux.free.fr/ ) instead of tar for recent disk archives. Source: over 1 year ago

Dar - Like tar, but can do incremental and differential backups with rsync-style binary diffs, only archiving what's changed (and without trusting mtimes like tar --newer does). Source: almost 2 years ago

Write compressed, encrypted, sliced archives of the lvm snapshot to HDDs mounted via USB using dar Dar will pause to change HDD every few TiB. Source: about 2 years ago
