Hi,

sorry this is not possible, fbackup does ALWAYS rewind the backup tape, even if you specify a no-rewind device.

BTW putting more than one backup on a tape is generally not a good idea. If you have a bad tape, you'll loose more than one day.

regareds,
Thierry.

Ok thank you but i can't use tar because
i have more than 2Gb.

About the tape I'll use 3 Dlt tape in mirror.
I hope that one of three is good !!!

Matteo,

It's very dangerous to append more backups to an existing backup, especially when using fbackup, because there are EOF (end-of-file) markers for at least these: tape label, volume header, index, data, and "checkpoints". You could use "mt -f /dev/rmt/0mn fsf 1" (note the "n" at the end of 0mn means no-rewind), until you hit the end of the last EOF marker, but you can't insure that you won't destroy the index. I suggest you use a new dlt tape.

Gnu's tar allows backups to be appended.

Matteo,

GNU's tar, PORT by HP, DOES backup files > 2gb! Plus it allows you to backup a system remotely!

Hi Matteo,

you can also use pax if you need support for files bigger than 2 GB.

see man pax

Allways stay on the bright side of life!

Peter

additional:

for installing software use swinstall, which opens a GUI for you

Matteo,

gunzip it, then use swinstall, where your "source" is the FULL path to the "depot" file.

You might have to execute the program using the full path, or copy it to a major bin directory, but rename it to gtar so that you don't overwrite the tar that comes with HPux.
