Can Bacula write directly to 3590 tape drives? I'd hate to have to restore an entire LVM pool to retrieve 1 file.
Do you have a link to Bacula handy? Michael Coffin, VM Systems Programmer Internal Revenue Service - Room 6527 1111 Constitution Avenue, N.W.

I'm also pointing out that DDR or its moral equivalent isn't the right answer EITHER. If you do it that way, sooner or later you will end up with data corruption. Here's one way you can do it with no additional licensing fees and no new software from the z/OS or z/VM perspective. Install a Bacula instance. Have your Bacula SD use a big LVM disk pool as its storage device. Arrange the scheduling so that the Bacula job mounts the disk pool, runs its backup, and then unmounts the disk pool when it's done, and further so that the Bacula backups are done before your nightly volume dump happens. Then dump the disk pool volumes, but NOT the other volumes on your Linux guests. Since they will be unmounted when the volume backup runs you know that they are clean. To restore, restore THOSE volumes and a basic Linux system with Bacula (which could be a separate DDR image, if you like). Mount the LVM and then restore your remaining guests from that pool. Didn't cost you an additional dime in software licensing fees.
