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.

gpodder-backup
GPODDER-BACKUP(1) User Commands GPODDER-BACKUP(1)
NAME
gpodder-backup - Backup and restore utility for gPodder user data
SYNOPSIS
gpodder-backup [--create|--extract] <archive.gpo.tar.gz> [options] gpodder-backup --purge
DESCRIPTION
This utility can be used to create a dump of the current gPodder data (configuration files + downloads), optionally replacing the real con-
tents of the download folder with zero-byte files (for submitting your data to a bug report without having to transfer lots of data).
OPTIONS
--version
show program's version number and exit
-h, --help
show this help message and exit
-c <FILE>, --create=<FILE>
Create a new archive
-x <FILE>, --extract=<FILE>
Extract an existing archive
-f, --fake-downloads
Store downloads as zero-byte files in backup
-n, --no-covers
Do not include cover files in archive
-D <DIR>, --destination=<DIR>
Extract downloads in different folder
-P, --purge
Remove current data (can be combined with --extract)
USAGE FOR BUG REPORTING
This command is useful if you want to report a bug in gPodder:
gpodder-backup --create bug123.gpo.tar.gz --fake-downloads
Backup your current data to file bug123.gpo.tar.gz, but don't store download data (create zero-size dummy files instead). You can
then attach bug123.gpo.tar.gz to the bug report.
If you are instructed to try gPodder from a "clean state", you can use the following command (be sure to backup your data before!):
gpodder-backup --purge
Remove all gPodder data, so you can start from a clean state
EXAMPLES
gpodder-backup --create today.gpo.tar.gz
Backup your current data to file today.gpo.tar.gz
gpodder-backup --extract mybackup.gpo.tar.gz
Restore (without purging) the contents of mybackup.gpo.tar.gz
gpodder-backup --extract default.gpo.tar.gz --purge
Remove current data, then restore the contents of default.gpo.tar.gz
gpodder-backup --purge
Remove all gPodder data, so you can start from a clean state
EXTRACTING FAKED DOWNLOADS
Please note that any existing downloads will be overwritten with zero-byte files when using the --extract option of the gpodder-backup
utility with a backup created with --fake-downloads
