zfsbackup
This is a collection of scripts that simplify the management of ZFS snapshots for filesystem backups.
*zfsbackup.sh
This script will maintain an incremental zfs snapshot that is mirrored on a remote system (today/yesterday).
*zfscron.sh
This script is designed to be run every half hour, and maintains a snapshot for the previous hour. To setup this script, add the following to the user's cronjob with permissions to perform snapshots
*/30 * * * * /usr/home/test/zfscron.sh
Note:
These scripts should be used by a non-root user setup and configured to create/destroy snapshots. The following will setup the necessary permissions for the zfs-user to manage snapshots for tank:
zfs allow -d zfs-user create,destroy,snapshot,hold,mount,send,rename,receive tank
