Hi,

How can i back up to Tape Drive using Unix UX ?

1. tar cvf /dev/rmt/0m ./user/dmn/test.dmp

2. tar xvf /dev/rmt/0m

but i can't see a a file , can u help me

I suppose /dev/rmt/0m is your tape drive.
After tar cvf, run "tar tvf /dev/rmt/0m" to list the content of the tape.

See man page of tar "man tar"

What is happening is the tape is rewinding afer the first backup. There are a couple of ways to fix this. First, if there are going to be several of these backups done consecutively, use the no rewind device /dev/rmt/0mn
Alternatively, you could use the mt command to advance to the proper position.
man mt to get more info.

I c , but i just want see ALL my backup files in the tape after i backup it to the tape.
If i use /dev/rmt/0mn , they will show one by one the file .

Tks for your kind

Hi,
Either you can use
tar cvf /dev/rmt/0m /folder1 /folder2
and so on in a single command or
use fbackup with graph file.
Create graph file with all the files/folder needed, then run fbackup with g option.

Read man pages of tar and fbackup.
