Big Comparison - Borg vs Restic vs Arq 5 vs Duplicacy vs Duplicati

Background:

I’ve used restic in the past and just started to use Duplicacy because pruning requires full downloads/repacking/re-uploads of most of the content with a restic repo - which just isn’t feasible with a slower internet connection.


I was wondering if you could expand your test a little, if you find some time:

  • It would be interesting how much traffic a purge/update/restore uses, as most people are not blessed with a gigabit internet connection :smiley:
  • Do you run VMs? While backing up pictures and documents are interesting, it would be neat to see how backing up several VMs looks like. Especially if they are not cloned, but installed individually. The disks should deduplicate very well, if the operating system and applications are similar.
  • It would be nice if you could test how well two different computers can deduplicate their backups onto one storage. I have a couple of computers with similar user-data and similar operating systems and would like to create backups from them onto the same storage and keep the disk usage at a minimum.
