I'm succesfully using it for 4 servers with two DDS drivers, and I would say it could be easy expandible to the numbers of tens. It have some "caveats" anyway. Rigth now it can't manage multivolume quite efficiently (a single dump must go to single storage device, for instance, and the multichanger specifications is a bit... "raw". Management for automatic tape cabinets is out of the system too. It uses an rsh-like client/server protocol to remote access systems so it's not soo secure -while it can be ssh-tunneled -not out-of-the-box. It doesn't support multiserial backups on a single config -but you can have multiple definitions so off-site monthly backups don't interfere with your monday-to-friday daily series, for instance). What it does pretty well is automatically balance the backup levels for all your partitions to optimize tape space and indexing your tapes (both semi-automatically indexing tapes and maintain the index about what was where... it can even help you the physical tape-labels, so you just print what amanda tells you to, and have some -primitive, ability to create graphic logs to help you planning capacity in advance). It will e-mail you too if you forget to put the tape in the drive too. Appart from this, it uses underlying backup tools (dump by default, tar or smbtar if you choose it) so you can restore even without amanda software present (while it's more difficult: you just don't have a tape labelled like "first-monday-of-the-month-so-level0-backups-here", but only something like "Comm-dpt-tape-no12": if you loose your indexes you will have to look at the labels for the dumps to guess what's in-there. Anyway, those indexes are simple text files so they're easy to copy to another box in advance, and they're sent day-to-day by e-mail to the backup operator, so you do have options to avoid that situation). -- SALUD, Jesús *** jesus_navarro@promofinarsa.es *** _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://www.sistina.com/lvm/Pages/howto.html
