Creates a snapshot for all btrfs volumes specified. Snapshot is named from the subvol name or if there is no subvol, from the path by appending -snapshot-YYYY-MM-DD-HH-mm.

To create regular snapshots on a daily base, just run:

sudo cp btrfs-snapshots.sh /etc/cron.daily/btrfs-snapshots

If btrfs-snapshots is run from a cron.daily, cron.hourly, cron. monthly or cron.weekly directory, the periodity is automatically appended to the snapshot name, and the expiry is set meaningfull.

Try: btrfs-snapshots.sh --help
