longDescription = ''
btrfs-auto-snapshot is a Bash script designed to bring as much of the
functionality of the wonderful ZFS snapshot tool zfs-auto-snapshot to
BTRFS as possible. Designed to run from cron (using
/etc/cron.{daily,hourly,weekly}) it automatically creates a snapshot of
the specified BTRFS filesystem (or, optionally, all of them) and then
automatically purges the oldest snapshots of that type (hourly, daily, et
al) based on a user-defined retention policy.
Snapshots are stored in a '.btrfs' directory at the root of the BTRFS
filesystem being snapped and are read-only by default.
