I've got my fulls, differentials, and incrementals each going into their own pool/directory on the NAS. I already plan to migrate last month's backups off the NAS onto tape for long-term storage. However, I'd also like to make a copy of this month's full backups onto a tape to take off-site. (Then I sync the incrementals to a portable hard drive and get the whole ball of yarn in a single duffle bag, and the portable drive doesn't have to have the full capacity of the NAS.)
I've tried bcopy and failed. I've tried just tarring the disk volumes, but it's hard to predict the end of tape and get efficient tape usage. So, I think I'm going to do some recursive baculating. (Is that a word? :-) I think I'm going to set up a job in bacula that will back up the full files to tape in another pool. Here's my thinking: if my NAS takes a total header, I'll need to restore from tape onto disk, and then from disk to the client machines. But if it's that much of a DR situation, I can live with that. Since pulling from tape onto disk is really only a first step, I don't need to bscan the tape...I can just brute force bextract it onto my shiny new NAS or whatever I'm using to be my new disk store. If anyone sees any nasty flaws in my logic there, please let me know. I'll try to share when I figure out whether it'll really work or not. Something else that just occurred to me that I might do at some point is to build a VMware image with a linux or Solaris build (I'm in a Solaris shop, but linux might be more universally useful) with a bacula install set up and running. Burn that image onto a DVD along with VMware player, and in a true DR situation I could set up a virtual Bacula server on just about any laptop or PC I could lay hands on to start my recoveries (assuming I had access to my backup media from it). But that's a bit further off for me. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
