Hi,
since i did not receive any reply to my post below, i repost.
Does nobody on the list backup his or her data to tape?
Or are you using other tools than dump?
Please help, since my new server is useless if i cannot back it up!
The question again: How can i write and retrieve more than one filesystem to one
tape?
TIA
