If you know the name of the files, you can do:
tar xvf <device> 'filename1' 'filename2'....
and so on. You should probably do a tar tvf <device> to find out what's on the tape (without writing anything) to check for relative/absolute paths etc.
Hope this helps.

You may want to invest in something that allows "Fast File Restores". Being that the tape is 40GB, using tar could take a while.
I am a happy user of Microlite Backup Edge. I use it with a Sony AIT-2 drive (50GB uncompressed), and it restores files from anywhere on the tape in less that 2 minutes.

ok, I do know thw file names on tape. Can I specify an alternate targert location for the tar as I do not want to overwrite existing files. Will it overwrite stuff to the orirginal directory whilst tar xvf.
Also, thanks for the microlite tip. I am investigating pon that as well.

Also Bruce,
How do you rate microlite against arkeia.
I understand that it is a compatible backup manager. But my requirements are this. Server is a redhat7.1 with 2.4.6 conected to a 1TB raid array and the backup medium is IBM 3581 autloader. There will be no over the network backups. The 3581 autoloader is a 7-tape with a bar code reader with two scsi devices. One if for the backup device itself and the other is for the robotic tape changer.
So how well would Microlite serve my needs, scheduled backups, quick and easy restores, et al.
Thanks.

Check out the website for device compatibility. There are many options in the latest version for scheduled backups. About the only complaint I have is the interface. Although I do like that it is text based, it is not the most intuitive. There are also many recovery possibilities, even booting of a bootable CDROM to do restores if you really get into trouble.
I really enjoy the fast file restore feature. It is so much faster than tar, and has paid for itself many times over, with quick restores for our Marketing folks
I'm not sure how it compares to arkeia, since I have never used it. Bruce Garlock

Sonun, you asked above about whether what you are restoring will overwrite what you already have. It depends on how your tar was written - as I mentioned above, do a tar tvf and check how the output is presented. This should tell you whether the files were written with absolute pathnames or relative ones. If you have a problem divining which is which, post a sample of the tar tvf here. HTH.

Thanks Ken,
Will post it asap. the device is held up by another process and hence.
But now I have another question.
after I did a normal backup like,
tar cvf /dev/st0 /home/file1
it goes through the entire backup and at the end it says,
tar wrote 0 of 10240 bytes (not sure about the exact number here !!!)
error unrecoverable. exiting.
But when I check with tar tf /dev/st0, it shows all the files were indeed backed up.
So now what should I do about this ???
