[Hampshire] Linux tape backup software

Hi,

Can I please have a list of backup software people use on Linux.
I want to have a dedicated Linux backup server that talks to the tape drive.
Then, a number of agents on various Linux and Windows machines that
send the data to be backed up to the backup server.

If anyone knows any pros or cons regarding any of them, that would
also be useful.
We could maybe then add the results to the hantslug wiki.

Thank you

James
