At the moment we are backing up our two filesystem /root and /u once every month using "backup 0...". Besides that we have a streamer tape permanently inseted performing automatic delta backups of the /u file system every night by doing "backup 9...". What happens is any of the tapes Im using is damage ? I suppose "backup" wont discover that. Can I perform a "restore" to /dev/null immediately after backup just to ensure that the tape is correct ? Does "restore" returns any exit code if there is some kind of checksum error in a tape block ? Same worries about the disk surface. Will "backup" return any exit code if it finds a bad spot on the disk ? Should one perform a fsck before backup ? How should one do this in a safe way ? Thanks in advance for any advice ! -- Bj|rn Smith Compound Systems, phone +46 8 7923689 UUCP: {uunet,mcsun}!sunic!comsys!smith Internet: smith@compound.se
