To DVD, "dar".

To an external HD via USB, rsync and the variants they have already told
you.



Cheers for an external USB hard drive.

Boo for the Rsync.

Rsync is NOT a good backup tool. Backups should be a point in time
image of the file system. Rsync wants to match changes on a file by file basis,
which means if you delete a file rsync dutifully deletes your backup
of that file.

Hello?

That's why you should use rdiff-backup instead of rsync. With rdiff-backup, you can restore that deleted file as long as you haven't started over.

Better to use something that can compress files and thereby
allow multiple backup images of the file system.

rdiff-backup is differential, i.e. it saves changes to files. This makes for a very efficient use of storage space, much better than simple compression.

I use BRU for this. I pay for it. Its worth it.

I back up to a USB drive, but it can also drive most tape drives
on the market.
