Time to get some backups going of the zfs file systems.

anouk:/work/scripts # zfs list
NAME             USED  AVAIL  REFER  MOUNTPOINT
storage         23.0G  43.4G  31.5K  /storage
storage/backup  1.32G  43.4G  1.32G  /storage/backup
storage/crash   24.5K  43.4G  24.5K  /storage/crash
storage/mp3     14.2G  43.4G  14.2G  /storage/mp3
storage/stuff   7.47G  43.4G  7.47G  /storage/stuff
storage/zones   24.5K  43.4G  24.5K  /storage/zones

Let’s start with the /storage/backup file system.

anouk:/work/scripts # zfs snapshot storage/backup@080118
anouk:/work/scripts # zfs list
NAME                    USED  AVAIL  REFER  MOUNTPOINT
storage                23.0G  43.4G  31.5K  /storage
storage/backup         1.32G  43.4G  1.32G  /storage/backup
storage/backup@080118      0      -  1.32G  -
storage/crash          24.5K  43.4G  24.5K  /storage/crash
storage/mp3            14.2G  43.4G  14.2G  /storage/mp3
storage/stuff          7.47G  43.4G  7.47G  /storage/stuff
storage/zones          24.5K  43.4G  24.5K  /storage/zones
temp                   23.0G  10.2G  23.0G  /temp

It’s that easy.  Any changes will be tracked to the snapshot so i can restore it to this point at any time i choose.

Now to send it to another system for redundancy:

anouk:/storage # zfs send storage/backup@080118 | ssh augustus zfs recv backup/anouk-backup

For the above command to work on the system augustus the zpool backup has to exist but the file system i am sending the snapshot to may not exist.

There, all done.  I have a backup of the file system anouk:/storage/backup at augustus:/backup/anouk-backup

augustus:/backup # zfs list
NAME                         USED  AVAIL  REFER  MOUNTPOINT
backup                      1.32G  6.24G  26.5K  /backup
backup/anouk-backup         1.32G  6.24G  1.32G  /backup/anouk-backup
backup/anouk-backup@080118      0      -  1.32G  -

Consult the zfs administration guide for more info on cloning snapshots as well.
