I'm sorry if this either obvious or has beaten to death... I'm looking for ways to backup data on a linux server that has been using rsync with the script `rsnapshot'. Some of you may know how that works... I won't explain it here other than to say only changed data gets rsynced to the backup data.
I'm wondering if I could do something similar by making that data directory hierarchy available on a osol.ll build 110 zfs server as an NFS mount. That is, can I nfs mount a remote filesystem on a zpool and use zfs snapshot functionality to create snapshots of that data? I'm not at all familiar with using zfs in general but was thinking something like: Make a directory hierarchy on a remote linux machine availabe for nfs mount. Mount the nfs share on osol server, inside a zpool. Do whatever is the correct way on zfs to create a snapshot of that mounted data and write it onto another directory also inside the zpool. A week later mount the same nfs share from remote linux machine and create a second snapshot written to the same other directory. Will that procedure produce a snapshot of first the full base data, and second time around only the changed data in comparison to the first snapshot? So proceeding in that manner, I'd have a series of snapshots were I could trace any differences in files? _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
