# Incremental backups with Btrfs snapshots
|
||||
#
|
||||
# This script does incremental backups of Btrfs subvolumes
|
||||
# across filesystem boundaries as proposed in the Btrfs wiki:
|
||||
# https://btrfs.wiki.kernel.org/index.php/Incremental_Backup
|
||||
#
|
||||
# It uses the 'btrfs send' and 'btrfs receive' commands.
|
||||
# Its not intended for simple snapshots in a single filesystem enviroment.
