Backup Tools

Hi All,

I'm using selfmade scripts together with afio/cpio to backup about 120GB
on DDS3 tapes (I know that there are better medias to store 120GB on,
but "the management" does not support better equipment). Although
everything works, I'm looking for a tool that enables me to restore
files easier, i.e. when I need to restore a file from tape#5 of a
certain backup, today I need to read through all tapes sequentially
since afio/cpio work that way. Is there any tool that is able to detect
the tape# on which the file I want to restore is on, so that I only need
to insert the specific tape (even commercial solutions)?

Regards,
Joerg
