hi all,

I have a problem on backing up a very large file size with 50G byte.
but, one backup tape can not fullfil in one tape. therefore,
i have to use a different tapes. may i know what is the command to enable it to able to backup in separate tape continues?

currently i'm using:

tar -zcvf /dev/st0 /backup

Thank you.

Hi,

And welcome to LQ!

Have a good look at man tar; specifically the -M flag.

is that
tar -zcvfM /dev/st0 /backup
?
after the first tape is full. then it will ask for second tape?

Thx

Almost ... the order in this case is (I believe) significant.

tar -zcvMf /dev/st0 /backup

And yes, it will prompt for the second tape.
