Tar / CPIO backup

[PVR]

Hi

I need to backup a 13GB file into two / three 4/8 GBtapes.

I want to get it done through tar, dd or cpio. I don't have any other backup software.

Can you suggest me a way to do this ?

Assuming this is a HPUX system you *do* have another backup tool - fbackup (there are man pages for more details). You can setup full and inceremental backups which span tapes, and even be notified when a tape needs to be changed - if this is a backup for a HPUX system, which will only ever be restored onto a HPUX system then fbackup is the way to go...

Sorry !

I forgot to tell you on that....

User is going to take backup form a HP Unix system and going to use it in a solaris system in a remote location....I believe fbackup will work only in HP-UX systems

Many thanks for your quick response

You can try a gzip on the file to reduce the file size to < 8GB (The limit for tar/cpio) and then back it up to either one or two tapes. tar will by default prompt for a second tape if the first becomes full.
(Assuming the file is not already gzipped)

Get gnu tar on both systems (the HPUX and Solaris host):

http://hpux.connect.org.uk/hppd/hpux/Gnu/tar-1.15/

http://www.sunfreeware.com/programlistsparc9.html#tar
(assuming your on Solaris 9 /SPARC)

This will backup files up to 64GB (IIRC)

I started using gtar and it worked fine for me.

Thanks to you all :)
