HP-UX System Administrator's Guide: Routine Management Tasks

the online index, which is produced after the last volume has been written (the index
created using the fbackup -I option).
Also, fbackup assumes all files remaining to be backed up will fit on the current tape
for the index contained on that media. Therefore, if you did not use the -I option on
fbackup or removed the index file, extract an index from the last media of the set.
Use the /usr/sbin/frecover utility to list the contents of the index at the beginning
of a backup volume made with fbackup. For example, the command
frecover -I /tmp/index2 -f /dev/rmt/0m
specifies that the device file for the magnetic tape drive is /dev/rmt/0m and you want
to put the listing of the index in the file /tmp/index2.
Backing Up NFS Mounted Files with fbackup
When backing up files that are NFS mounted to your system, fbackup can only back
up those files having “other user” read permission unless you have superuser capability.
(To recover the files, you will need “other user” write permission.) To ensure the correct
permissions, log in as superuser on the NFS file server and use the root= option to
the /usr/sbin/share command to share the permissions, then back up as root. For
more information, see share(1M) and the NFS Administrator’s Guide.
Examples of fbackup Commands
Here are a series of examples showing a variety of ways that fbackup can be used.
Example: Backing Up to a DDS (DAT) Tape
For this example, we want to do a full backup and do not care about doing future
incremental backups. Therefore, we do not need to specify a backup level (nor do we
need to use the -u option to update the dates file). We could also specify “level 0” to
indicate a full backup.
fbackup -i /home
Example: Backing Up to a DLT Tape
(You plan to do a future incremental backup.)
This example will back up the entire structure except the invoices directory. The
device file for this example is /dev/rmt/1h, specified using the -f option. For this
example, we need to plan for the incremental backup (next example), so we must do
three things:
1. Use a graph file to specify which files will be included/excluded.
2. Specify the -u option to update the file /var/adm/fbackupfiles/dates.
3. Specify a backup level.
