tar and cpio are not capable of doing incremental backups. You could make them do it, but it would require a LOT of scripting.

As mentioned above, fbackup would be your best bet. fbackup can handle fulls and incrementals with no problems.

There is an option in tar which might be of your help.

tar -u

This will tar only the updated files and leave the rest.

Hi,
As explained earlier "fbackup" is the command avaible on HPUX to do incremental backups. You can use it as:

# fbackup -v -g gfile -u -2 -f /dev/rmt/0m

Here /dev/rmt/0m is your backup device. -u option updates /var/adm/fbackupfiles which keeps track of the history of the files. Now that if you are executing this for the first time it will be a full backup and not incremental. -g is used to backup selected files specified in gfile which is a normal text file.

Now in order to take incremental backup next time you need to change the level to 3 and then all files modified since level 2 backup will only be backuped during level 3 backup.

# fbackup -v -g gfile -u -3 -f /dev/rmt/0m

See man fbackup for more details.

Hope that helps.
