Incremental backup via ZFS

[bsus]

Hi,

I have added another independent zpool to my server which should work as fallback.

The main storage is a raid1 with two drives creating daily snaps with zfSnap.

Is there a magic tool which helps me backing up the data from the main storage to the backup storage or do I have to stick to rsync?

Best Regards,
bsus

[CMD=""]zfs send -R -i pool1/data@yesterday pool1/data@today | zfs receive -Fduv pool2/data[/CMD]

You just need to remove ssh root@$host from the script.

Hi,

Sorry for reopening this thread. I fail sorting out a solution how to use # zfs send with zfSnap. I would like to keep on the main storage a timeline from 30 snapshots. The backup storage should get the data incremental and than store them for 90 days. How do I do this best? Do I need to write a script full of regex?
