using ZFS on an external USB drive for backup in Ubuntu

backup zfs

Solution 1:

Assuming your USB disk is /dev/sdb and will be used exclusively with ZFS:

zpool create pool sdb
zfs create pool/backup

Use /pool/backup as your rsync destination directory.

Create snapshots with:

zfs snapshot pool/backup@$(date +%Y%m%d%H%M)
