This script creates a backup using rsync of a local or a remote directory. Environment variables are used to configure the script. When MAX_AGE variable is set it calls a second script on completion. All log output of rsync and scripts are sent to docker if --log-file=/dev/stdout is set. SSH option is currently off. By removing the # in disk-backup.sh in the ARGS you can enable it.
I run a local crontab to run the container daily.
TARGET_DIR= # path where the backups are stored
SOURCE_DIR= # local or remote path to backup eg. /home/foobar OR foobar@some.host.com:/home/foobar
SSH_OPTIONS= # ssh options to pass into rsync eg. -o UserKnownHostsFile=/dev/null
RSYNC_OPTIONS= # additional rsync options
MAX_AGE= # oldest backup to keep in days, anything older will be deleted. If not set, it's ignored.
EXCLUDE= # option to exclude folders that you dont want to be backupped.version: "3"
