Duplicacy VS tarsnap

I have been having great luck with incremental backups with the very similar named Duplicacy https://duplicacy.com/

Pro: No need for a special index database. The chunks are placed in the file system. This explains it in greater detail. Seems to place great emphasis on reliability, which is important for me. Versioning is also supported.

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.

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 drive occasionally that I keep off site.

I use Kopia and works well. Have also used this https://duplicacy.com

Tarsnap for configs and critical stuff (password database, emails).

Someone does :)

Colin Percival's tarsnap

In past threads, people have mentioned enjoying my Tarsnap (https://github.com/Tarsnap/tarsnap) code. I personally think that the spiped (https://github.com/Tarsnap/spiped) code is even better.

I prefer Vorta myself ( https://github.com/borgbase/vorta ) as it also has incremental and encrypted backups, as well as being a fraction of the price, but tarsnap seems to still be in very-slow development: https://github.com/Tarsnap/tarsnap , so I'd say from a quick look it's still trustworthy.

Each server also upload their configs and « important » data (my mails and git repos) to tarsnap 3. Tarsnap storage is not as cheap as B2, so I try not to upload too much data there, but it's reliable and easy to use. It was also my first backup solution, and barely cost me 10$ a year so I keep it as a secondary backup.

Not foolish! The Tarsnap client code is open source, but the license file prohibits anyone from using the code: https://github.com/Tarsnap/tarsnap/blob/master/COPYING

Yes. For the curious,
