Change ZFS snapshot name using pve-zsync

[Whatever]

Is there any way to change ZFS snapshot name format in order to be able to sync VMs/pools with external ZFS (FreeNas box for example)

In particular FreeNAS does not support ":" and/or "-" in snapshot name:

root@pve02A:/etc# pve-zsync create --source tank --dest 172.16.252.254:tank/datastore/pve/pve_zsync --verbose --max                                                                     --name test1
Use of uninitialized value in concatenation (.) or string at /usr/sbin/pve-zsync line 902.
send from @ to tank@rep_test1_2016-11-24_18:33:39 estimated size is 9.50K
total estimated size is 9.50K
TIME        SENT   SNAPSHOT
Job --source tank --name test1 got an ERROR!!!

Not tested with snapshot, but normal dataset can be renamed. For example:

zfs rename -p rpool/backup-pvezsync/steamlinux rpool/backup-pvezsync/virtu01/steamlinux

Hi,

no it is hard coded in pve-zsync.

Sorry for the OT, but i'm a ZFS newby.
The command wrote in the first post is making a local ZFS snapshot and send it to a different server ?

Yes, but the remote server must have zfs.

 

[Alessandro 123]

Can this be used as a quick way to do backups? are these kind of snapshot incrementals?

 

[wolfgang]

The first job(sync) is not quick but yes and yes.

 

[Alessandro 123]

What happens if on the destination server i'll delete a middle snapshot or the older snapshot? the following are still consistent even loosing their parent?

 

[wolfgang]

Yes is is zfs and always consistent.
