zrb (ZFS Rsync Backup) is a simple and rough solution to manage backup with the 'rsync' + 'zfs snapshot' commands. It is running from a central backup server and works pull mode.

Features:

• pull mode backup
• resuming backup job ot of box
• excluding via rsync exclude file
• optionally different pool/dataset name
• various expiring rules
• parallel jobs with configurable process number
• command to add and list vaults

VAULT: backup directory where backed up data and config files kept. Each VAULT has 3 directories: config/ -> per VAULT config files data/ -> copied data log/ -> logs

• local (mounted) directory

$ zrb.sh -a /path/to/backup/source -v VAULT

• remote source (rsync syntax)

$ zrb.sh -a hostname:/ -v VAULT

Initializes zfs dataset of the VAULT and necessary directories and define rsync source.

$ zrb.sh-v VAULT

• expire only:

zrb.sh-e only -v VAULT

• backup + expire:

zrb.sh-e yes -v VAULT

$ cp zrb-ruanall /etc/cron.d/

$ chmod 644 /etc/cron.d/zrb-runall

Change whatever timing and frequency (eg. hourly, daily, weekly, monthly) you prefer.

$ zrb.sh -l VAULT
