Today I finally managed to set up an incremental backup for my workstation. What do we need? Well, nothing more than rdiff-backup, an opensource command line tool with all the powers you need.
it just backups. and your last backup is always available 1:1 at the destination (no strange storage formats etc., just dirs and files). Diffs and metadata are stored separately. So if you want a
backup that does its job, is plain, is easy to restore, has no unneccessary features and “just works” than rdiff-backup is the right tool for you.
Here a small bash script I write to accomplish the mission:
#!/bin/bash P=/home/soenke DESTINATION=mydestionationserver.local INCLUDE=" $P/Documents $P/.gnupg " echo "$INCLUDE" | rdiff-backup --include-filelist-stdin --exclude $P/ $P/ $DESTINATION::/home/soenke/backup
In my case “mydestionationserver.local” is a local mediacenter server running Ubuntu and a SSH server. INCLUDE has one backup src per line. P is the prefix dir, in my case my homedir. As you can
see, I’m using a whitelist of dirs/files to be backupped. If you want your full homedir get saved, just use:
rdiff-backup /path/to/src <server>::<destination-dir>
Just check the examples to learn more.
