remote-btr-backup
usage: remote-btr-backup.sh options
This script creates a copy of a local folder as a snapshot on a remote btrfs volume or a thin provisioned LVM volume.
Dependencies on the local system are ssh (with shared key setup) and any bourne shell (i.e. busybox ash).
On the remote system snapper (snapper.io) must be installed and configured.
OPTIONS:
-h Show this message
-n Backup name
-d The directory to back up
-b The backup directory
-m Optional: A local directory to create an intermediate mirror of the directory to back up
before sending the data to the remote system. This will improve the consistency of the backup
as the local mirroring is usually a lot quicker than writing to a remote system.
-r Optional: Backup host (hostname or ip or ssh alias)
-s Optional: Snapper configuration on the remote system to use for snapshots.
-c Optional: absolute path to a configuration file with the required options.
Following variables must be set:
BACKUP_NAME
SOURCE_DIR
MIRROR_DIR
TARGET_DIR
Optional variables:
MIRROR_DIR
TARGET_HOST
SNAPPER_CONFIG
Dependencies
- rsync: must be installed on both the local and the remote host.
- ssh: The remote host must run an ssh daemon. The backup user on the local system must be able to log in
to the remote system automatically (key authentication, any required ssh arguments must be set in the ssh client
config under
~/.ssh/config)
