Noob question:

let's say I have two identical drives, A and B.

Let's say I want to reduce data loss chances to a minimum.

Would it be better to:
1) setup a zfs mirror with both A and B
2) schedule a recurrent rsynch backup from A to B

Boosts most welcome :)

Thanks!

2) rsync to the second drive (zfs/btrfs fs with hourly snapshots)

@cretox @Antanicus @Radamanth In our environment we use a straight rsync back-up, due to our users' needs: restoring single files and/or directories on demand

@desantis @cretox @Radamanth
Yes restoring files will be the likeliest scenario for my use too (a self-hosted nextcloud instance)

In that case, I'd suggest rsync since it is trivial to configure and you'd get immediate results. If you have the space, its incremental option is cool since it will only back-up changed files.

The two drives are identical, so this should be a reasonable option, I guess (A can't overflow B if they are the same size, right?)

@Antanicus

As long as you don't use the incremental option, space will not be a concern. The incremental option will utilize more space and could lead to overruns if not policed.
