Using rsync to maintain backups on Linux

Following on from my previous article, regarding Setting up and using NFS on Ubuntu, here's how I keep backups for quite a few clients.

On a particular site I maintain a single backup server that several clients backup to on a nightly basis.

rsync is great. Its one of those incredibly old, under rated and under used tools that come with pretty much all Linux distros.

The following rsync command takes a backup of a directory on a server and backs it up to another whilst keeping a backup of orphaned/deleted files over NFS.

rsync -ahvz --exclude=*.log --backup
--backup-dir=<DESTINATION SERVER SHARE>`hostname`/orphans-`date +%Y-%m-%d`
--delete --delete-excluded <DIRECTORY TO BACKUP>
/<DESTINATION SERVER>`hostname`<DIRECTORY NAME>

Simple as.

Note: Remember to clean up your orphaned files on a weekly/regular basis or your hard drive will soon fill up.
