Question : Problem: Backup for multiple filesystem into tape

We have AIX 5.3 and we are taking backup for some of the flesystems to tape (LTO2)
The below command which we are using for taking the backup

find /var -print | backup -i -v -q -f /dev/rmt0
find /etc print | backup -i -v -q -f /dev/rmt0

But from this above command the tape is getting overwritting from one filesystem to another filesystem for example from this above command the /var filesystem is going to overwrite with /etc filesystem , when we are listing the tape only it will display /etc contents..

But i want to append multilple filesystems..and i want to view both the filesystems ..( for restore).

Answer : Problem: Backup for multiple filesystem into tape

I don't know AIX, but Solaris and Linux use a "no-rewind" device to achieve this.
So try /dev/nrmt0 instead of /dev/rmt0.
