vbe is right. "fbackup" is not enough.
I would also like to add that "fbackup" in common with many of the unix feebies such as "dump" does not deal with large files (above 2Gb). It is also not accepted as a backup by HP support.
If you want to be able to recover from a system disc failure you should first make an Ignite backup and repeat that backup every time you make a significant change to the system configuration. Don't forget to record the current root password against that backup.
Then also use proper backup software (e.g. HP Omniback aka. Data Protector) to back up every file bearing in mind that "files" backups do not back up the Operating System properly - hence the Insight backup.
Don't forget to quiesce filesystems before you run a backup. In the basic case this mean stopping any databases and ensuring that no files are open. There are techniques available to keep database engines such as Oracle running during a backup.
It is advisible to rehearse and document the restore again-and-again to an expendable computer until you are confident that the restore works. If you are meticulous in your Insight backups or /dev/vg00 you may just need to bring /etc/passwd up to date before restoring the individual filesystems from the secondary backup.
Dealing with "fbackup" or "dump" process which go onto a continuation tape needs technical knowledge and planning. Imho you need to break the backup down into separate tapes by careful sizing and planning. i.e. Make each tape a separate backup operation containing one or more distinct disc partitions and don't let the backup software ask for a continuatation tape.
Imho. The best technique is to place each filesystem backup onto a separate tape partition and then use "mt" commands to navigate the tape. This is not necessary with HP Omniback because it recognises different mountpoints.

amverify
AMVERIFY(8) System Manager's Manual AMVERIFY(8)
NAME
amverify - check an Amanda tape for errors
SYNOPSIS
amverify config [ slot [ runtapes ] ]
DESCRIPTION
Amverify reads an Amanda format tape and makes sure each backup image can be processed by amrestore and, if possible, the appropriate
restore program (e.g. tar).
Amverify runs amrestore on each file of the tape and pipes the output to a restore program (if available) with an option to create a cata-
logue of the backup. The catalogue itself is discarded. Only the success or failure of the operation itself is reported.
If the backup image cannot be processed by the restore program, e.g. if it was written on a different operating system, the image is sent
through dd to /dev/null. This still determines if the tape is readable, but does not do any internal consistency check on the image.
If config is set up to use a tape changer, the slot argument may be used to choose the first tape to process. Otherwise, the current slot
is used.
The runtapes configuration parameter determines how many tapes are processed unless it is specified on the command line.
See the amanda(8) man page for more details about Amanda.
