|
|
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.
