Look also at revision control. svn, git ...

In addition to offsite backup

Although there is a lot of material regarding this available online, I want to highlight a few things for the scenario you specified:

Save in multiple places.
Don't save backups on public servers, especially if the backups concern the servers themselves.
You can mount anything at /backup, it must not necessarily be a partition. Think network locations (samba, sshfs,...).
If the backup's goal is to persist changes, not to save the files themselves, consider using git.
If you want to get creative, create a new user named "backup" with an own /home folder, own permissions and automated jobs.

Please provide us with more details of your current situation and goals if you need more specific help.

OVERALL: I would use an external hard drive coupled with an online backup solution like CrashPlan; but you can do everything with rsync and ssh too if you wanted. Many ways to do that task.

The HOW: I use Simple Backup (Debian/Linux Mint/Ubuntu) (sbackup) which stores files incrementally daily with full backups weekly, also using the Logarithmic Purging enabled. Again, many methods, but this is the one I have chosen to use. It works for me, probably will for you, but ultimately it's your call to make on whatever method you decide to use.

The WHAT: If I'm backing up the OS and applications, I use remastersys If I'm backing up the OS, applications, configurations and personal files, I use CloneZilla. If I'm backing up a one or more directories of files, I use Simple Backup.

I also have a custom script which creates, backs up, and tar.gz certain configuration files.

The WHERE:

I backup to 3 places....

1) A 2nd internal hard drive 2) An external hard drive 3) Online Storage space

All of these can be (and are in my case) automated. You could aos do RAID 0+1 as well for the internal drives.
