How to perform full backup.Need urgent help.

Hi All, Below are my commands, that I use mt -f /dev/nst0 oem for full backup. However, when the operation completes, the system backs up only the new files instead of appending the new files to the existing ones. mt -f /dev/nst0 oem tar -cvf /dev/nst0 /Disk05 tar -cvf /dev/nst0 /Disk04 to verify the tape archieve's contents tar -dvf /dev/nst0 or tar -tvf /dev/nst0 . The output is the files on this Disk04 only. Anyone has a fix, please help. Thanks a lot Trang --------------------------------- Do You Yahoo!? Yahoo! Shopping - Mother's Day is May 12th!
