Hello everyone, I've got one Question. Is it possible to use amanda without tapes? I don't use a tape for Backup! I've got only one big Harddrive, where i could store the huge backup files. How can I configure amanda without the use of tapes, so that I could backup my files on a harddrive. Amanda shall backup all my files in one directory. thx for your response Andreas
RE: The use of Amanda without tapes ?
Andreas, I myself have been working to this end off on for a while now. It just so happens that this week, I am attempting to finalize my backups to Disk. I suppose you could do the holding-disk trick the other guy mentioned. But if you want to use a large disk to mimic several tapes, thus allowing you to do the amrestore thingy from the clients, some other people have created some tutorials/examples of how they've done it. I recommend looking all these over. First do a search for a message from a guy Clinton Hogge in the amanda-users archive. He has a good e-mail RE this. Second, a guy Alex Muc also wrote a tutorial, do a search in the amanda-users archive in Yahoo for that one too. I tried finding these files myself in my archives, but all I can locate is the printed version. If I come across them again later, I'll e-mail them to you. Hopefully the authors wouldn't care.

Hi, Byarlay, Wayne A., on Dienstag, 25. Mai 2004 at 16:51 you wrote to amanda-users: BWA I suppose you could do the holding-disk trick the other guy mentioned.

You could find them in the archives at http://marc.theaimsgroup.com/?l=amanda-usersr=1w=2 Please be aware of the fact that the mentioned howtos refer to the use of chg-multi which is considered old-school due to the facts mentioned in the current HOWTO-FILE-DRIVER. The chg-disk changer-script is the more logical way and even easier to set up. You wrote if you want to use a large disk to mimic several tapes From the HOWTO: The script chg-multi handles many drives with a tape in each drive. The script chg-disk handles a library with one drive and multiple tapes. You can find the HOWTO in the current AMANDA-tarball in the docs-subdir, or online, for example at http://www.oops.co.at/HOWTO-FILE-DRIVER.htm -- best regards, Stefan Stefan G.

Re: without tapes
Put /dev/null in for your tape device when running the amdumps, then set it to a real tape and do an amflush. Wasn't there a comment on this list before about using something non- existent (like /dev/nosuchdevice) instead of /dev/null because amanda was somehow 'aware' of /dev/null and would perform backups differently? Absolutely correct. Do **not** set tapedev to /dev/null unless you really want Amanda to throw all your data away. That feature is meant for debugging, performance test, etc. At 2.4.3 this changes to null: and /dev/null goes back to an older behavior of throwing an error (since you cannot rewind it :-). But I would still strongly recommend the /no/such/device technique -- you know for certain what's going on with that. Frank John R.

Or better to touch /dev/nosuchdevice and then? Point to it the changer-device or the tape-device? Thanks
Re: without tapes
and... what about changing /dev/sg0 and /dev/nst0 and /dev/st0 (which are my devices) permissions? As long as you're not running as root, I guess this is OK. Seems like a lot of work and potential for messing up to me, but whatever you're comfortable with. BTW, you shouldn't be using /dev/st0 anyplace. Or better to touch /dev/nosuchdevice and then? Point to it the changer-device or the tape-device? Why touch it? The whole point of the excercise is to point at a device that does not exist, which will cause the open to fail, which Amanda already handles. And you'll want to leave your tape changer out of all this. Just comment out tpchanger in amanda.conf when going to the holding disk. John R. Jackson, Technical Software Specialist, [EMAIL PROTECTED]

Re: without tapes
Is it possible to run amanda without-tapes so it dumps only to holding disk? Set tapedev to /no-such-device. Amanda will not be able to access that as a tape device and fall back to degraded (incremental only, unless you change reserve in your holding disk definition) mode. John R.

If this is what you want to do, just don't put a tape in on Mon-Fri. Then do your amflush(es) on Friday. Note that you'll need to set your reserve to a low number to have room for full backups and you'll need enough holding space. Also keep in mind that if that disk crashes on Thursday night/Friday morning, you've lost a week's worth of backups... -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
Can't find info about using AMANDA without tapes
I have done a little work configuring AMANDA with tape backups, but now I am researching a way to back up to a separate disk array, and avoid using tapes altogether. Does anyone know where should I be looking for such info? Terry Dixon Webmaster Developer (312) 321-3182 Chicago Sun-Times www.suntimes.com
