Relplicate or Duplicati?

[Shamanix]

I am considering using duplicati instead of replicate on my truenas for remote backup to my brothers truenas. Our thought was that replication "could" make it more difficult than necessary in the future if on of us for example switches to a system without truenas. Also if f.eks my nas got hardware failure and i dont plan to set up a new truenas machine, it will be tedious getting the data back on f.eks a normal desktop with ext4. Third thing is compatability issues with encryption, what happens if i end up having a fulle updated zfs system, and my brother has an old zfs system? Then the encryption won't be compatible as far as i know, without "forcing" him to update. We want to have an easy system with as little as possible maintnance, and we don't to be more dependant on eachother than needed.

Will Duplicate be the way to go? Replicate? Other system?

Why not reciprocal rsync+SSH tunnels? If one of your requirements is to be able to replicate regardless of the source and target filesystems, vagaries of encryption, and quirks with zfs send/receive between different versions, this is pretty much the simplest you can go.

Thanks. Thought rsync was used mostly for standard syncing? I want a setup that takes care of all changes for me. For example deleting and moving files that has been deleted moved on my local source, and which only do incremental backups. I know Duplicati is made specificaly for backups and can handle all those things.

Copy-Paste from another forum: rsync is for synchronization, and Duplicati is for backups. With Duplicati you get deduplication and efficient storage of multiple versions. With rsync you only get one version. If a file gets corrupted and you don't discover it before your next rsync, the file will be unrecoverable.

Rsync will only send delta changes, which is essentially incrementals. You can also rsync backups via the --backup and --backup-dir options to save versions of the source into a backup directory tree.
