List contents of a tape
When I try to list the contents of my backup tape (backed up using bacula), either using the command tar tvf /dev/nst0 or the filesystem backup module of webmin I get the following error:
tar: /dev/nst0: Cannot read: Cannot allocate memory
tar: At beginning of tape, quitting now
tar: Error is not recoverable: exiting now
How can I fix this, or how do I go about listing the contents, or restoring the backup if for example I wasnt using my backup software - bacula.
Many thanks in advance
