ZFS data corruption bug about zrepl HOT 8 CLOSED

to me, that sounds way out of scope for zrepl.

you could probably hook something up via zrepl's hook system though?

zrepl is not a backup solution, is a snapshot one. You should have a proper backup solution that tests your backups. Nothing is safe in this world.

I use Kopia as a backup solution for local and remote copies, it has checksum and all the good stuff a backup needs to have.

I don't follow you... why don't you consider zrepl as a "backup solution"? The word "backup" is mentionned several times in the manual and I don't see how it couldn't be used a a backup solution. I was using Bacula before and it took several hours (sometimes more than a day) to perform an incremental backup (checking file one by one isn't scalable)

You're right, what I meant is that it is not the whole picture... The snapshot is not the backup itself, you need more tooling to have everything sorted out.

Anyway, I don't believe that adding checksums for example would be even feasible.

The only missing thing is a searchable catalog-like, otherwise I think you can achieve everything with zfs (send/recv, clone the snapshot, promote it if you want, etc).

It's important to check the snapshots, I don't like relying only on one tool for consistency.

This is why I maintain a remote server running Debian Linux (primary servers are FreeBSD 14) and rsync data over from the primaries. Then I do local snapshots. There are a number of other options. rclone direct to B2 is pretty easy to get set up and is fairly inexpensive, for example.

zrepl's scope is ZFS replication, which can be used as one component of your backup strategy.

Integration with VFS-level backup is out of scope.
