RE: Tapeless: how to make a SECOND backup

You have the right idea.  On my system, my second disk is mounted as
/backup.  Each 'tape' is a directory in /backup.  /backup/holding is my
holding area.

Each 'tape' directory has a structure as well: 

drwxr-xr-x    2 amanda   disk         4096 Oct 30 00:58 data
-rw-------    1 amanda   disk           11 Oct 30 08:00 info

I believe you have to create these before Amanda will use the 'tapes'.  If
you can label them, you're golden.  So two tapes would look like:

        /backup/tape1
        /backup/tape1/data
        /backup/tape1/info

        /backup/tape2
        /backup/tape2/data
        /backup/tape2/info

... and you would tell the changer you have two tapes called /backup/tape1
and /backup/tape2:

        slot 1 file:/backup/tape1
        slot 2 file:/backup/tape2

Create the data dir and info file with the correct permissions and owner
before using amlabel and amtape.  Once you have it set up correctly, both
programs will work properly as will amcheck.

Amanda behaves *exactly* the same with file 'tapes' as it does with tape
tapes.  The only difference is in the setup, data location and performance
characteristics.  So you have some new things to do to set up the file tape
system with the changer but once you've done that, its all the same.
