Napp-IT has a commercial (Pro) Replication module available that performs ZFS snapshots and pulls them to another ZFS server.
Snapshots are automatically mounted (read only) under /$FILESYSTEM/.zfs/snapshot/$SNAPSHOTNAME
. You can use the CLI to copy data you want to recover to another location.
Example with a (three level) nested ZFS filesystem showing an NFS storage repository containing VHDs:
/toplevelfs/midlevelfs/bottomlevelfs/.zfs/snapshot/job-name-job-ID_year.month.day.hour.min.sec/nfs_sr_id/
As with snapshots, creating a clone (writeable filesystem) is nearly instantaneous and initially consumes no additional disk space. Clones can only be created from snapshots.
If you don't want to muck with the .zfs
hidden folder, you could also:
You can use the ZFS rollback feature to discard all changes made to a file system since a specific snapshot was created. The file system reverts to its state at the time the snapshot was taken.
For most rollback cases, using Windows and Previous Version is the suggested method for a roll back as you can restrict the rollback to files and folders.
You can use Napp-IT menu ZFS-Filesystem → Rollback to initiate a rollback.
