[Tfug] backup drive

[arizray at comcast.net]

I am using Ubuntu 8.10 on a P4 machine, 2-80gb hdd, 1.5gb mem. I wish to take my second drive that is dual booting Suse 10 and convert it to a storage drive that would house a copy of HDA's home directory, photo's etc. 

Where can I get some guidance? Could I for example just change my boot grub file to eliminate the dual boot and change the partitions on HDB to suit my needs for storage?

I was thinking I could use snapshot to do the backup.
