without tapes
Hi, Is it possible to run amanda without-tapes so it dumps only to holding disk? But what I mean is not to take off the tapes physically but disabling tape writing. I want to accumulate incrementals worth a week and flush them on friday to a tape... How can I do such a thing?

Sorry if this subject is off topic but can you use a 40/80 DLT tape in a 35/70 DLT tape drive. Although we'd only be using it as a 35/70 tape. - David Flood Systems Administrator [EMAIL PROTECTED] Tel: +44 (0)1224 262721 The Robert Gordon University School of Computing St. Andrews Street Aberdeen -
Re: DLT
technically yes. A DLT-IV tape is the tape of choice on a quantum 7000, and quantum 8000. I do not know, however, if the tape that was written with a 7000 series, and later re-used on an 8000 if it would be reliable . I suspect that it should work. But for a definitive answer, give www.quantum.com a call. David Flood wrote: Sorry if this subject is off topic but can you use a 40/80 DLT tape in a 35/70 DLT tape drive.

Unloading tapes when task done ?
It seems like when the whole procedure ( whether its labeling tape(s), amchecking tape, or amdumping ) is complete, the tape is left in the tape drive in an on-line state. Is there some reason why the tape is not at least rewind-offlined, or for tape changer folks rewoffl/unload'ed back to the carousel slot when the job/task is finished? Just my 2 cents

Re: Unloading tapes when task done ?
Is there some reason why the tape is not at least rewind-offlined ... Because other users specifically asked for it to be left alone (we had to remove code that used to rewind after each operation). I assume they run something else after amdump (for instance) to tack on a little more data to the tape. And in the case of a changer, offlining the drive may cause other things to happen, such as dropping the stack and loading the next tape, which might not be what you want. Better that we leave things alone and if a particular setup needs something different, it's easy for them to do. John R. Jackson, Technical Software Specialist, [EMAIL PROTECTED]

Re: Unloading tapes when task done ?
Guess I'm from old school. Older 9trk drives when left on, continually have the vacuum on, and under constant tension. Its not healthy for the tape. Does that happen with a DLT tape, how about the DDS tapes. I would NOT like a live tape to be left in the drive for long periods of time. Who knows when a power failure will hit, who knows when the drive will go awol. An unloaded tape, immediately after backup, is safe from other folks, as well as the server, writing onto it.

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.

Re: back up data on holding disk only
On Tue, 2 Apr 2002 at 6:16pm, Julien Boret wrote I want to back up my data on the holding disk only. Every time I put a tape in the tape drive, Amanda will first try to back up the data on the tape and will only back up the data on the holding disk if there is no tape in the drive or if there is a problem with the tape. I would like to know if there is an option I can specify in the amanda.conf file that would tell Amanda to always back up my data on the holding disk without looking first if there is a tape in the tape drive. If you *never* want that config to go to tape, you have two options. With 2.4.2p2, just define your tapedev in amanda.conf to be /dev/no/such/device or some such thing. Amanda won't find the device, will go into degraded mode, and will put everything on the holding disk. With 2.4.3bN (note the b for beta), you can use files on disk as if they were tapes. Details on this are in the mailing list archives and in amanda(8) distributed with those versions. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University

Re: Unloading tapes when task done ?
Maybe they can OPT-OUT of the feature, but on a busy site, allowing the customers to access the tape drives, would appear to make good business sense. Particularily when the drives are doing just nothing. /gat btw, what do u mean each operation. Each run? If funny things happen, maybe they should be addressed.

Problems getting client to work.
Hi all, I've got a|some problem|s ;) getting amanda 2.4.3b3 running as client. One problem is that I don't know how the backup-server is set up, so I wonder if anyone here can see sthg in the logs below.

effects of changing dumptype?
Will changing the dumptype of a filesytem in the disklist cause any problems later if I need to restore a backup using the previous dumptype, or does Amanda automagically figure out what was used? Should it only be done immediately before a level 0 or would it not matter if the incrementals were different from the full?

A few interesting problems (tapeless, interactive restores, etc)
Hello, I am implementing AMANDA at my current workplace (used it once before and loved it) however I have a few strange circumstances and questions regarding my options. If anyone can help me with the below it would be appreciated. First off, for reasons beyond the scope of this email, my AMANDA server has no tape device. I am sending all backups to the holding disk. We also have a large IBM tape library running ADSM that I would like to incorporate into my AMANDA backup strategy. In my head, it will go something like this: 1. AMANDA schedules and performs backups to holding disk. 2. Every night, after AMANDA has completed her backups, the dated directory is moved over to our ADSM server. 3. The holding disk is wiped clean (space saving measure, ADSM will have the files anyway). 3. The ADSM server spools the directory to tape. 4. I write a wonderfully sexy amrestore-wrapper script that will take three arguments: * machine name * files to be restored * date of file you want to extract 5. Wrapper script figures out which dump directories it needs to get out of ADSM, gets them, and then runs the appropriate amrestore commands to seemlessly restore said files. I have a couple of problems (i.e. things I'm not sure about or are too stupid to understand) however and they are as follows: A) I need a way of asking AMANDA, If I want foo file from 3/20/2000 on machine bar, which dump 'directories' will I need? I have read and re-read the man pages for amdump, amadmin, etc., but the answer is not immediately obvious to me. I understand AMANDA usually works with tapes, but since even amrecover will look into holding disk dated directories, surely there's a way to get this info from AMANDA (without actually performing the restore, all I want is the dated directory names so I can pull them out of ADSM and slap them back into the AMANDA server's holding disk, so that amrestore/amrecover can get to them). B) After writing the above, I'm not sure I remember what my second problem was, or if it was relevent if (A) is solved. Sorry. I think it had something to do with piping 'amrestore' output to tar not being interactive as it could be with dump/restore. In other words, I want our tape monkies to be able to interactively restore files, but if I'm using GNU tar all I can do is request specific files. Eh, but that's ok I think...sorry... Anyways, I know this is long and rambling. I appreciate any help on the above, or even different strategies if the one presented is on crack. Thanks. -- Greg Mohney Technical Specialist, UNIX Administration APAC Customer Services (319) 896-5027

A trashed tape, even to the poor schlep who believes in you, is of no use to anyone. When you are finished, take the tape out, and put it in a safe place. BTW who said it was, or has to be hardwired. it need not be any more 'hardwired' than dumpcycle 0, or compress none, or simply a EjectWhenDone yes . BTW#2 you should be doing an amdump BACKUP; amtape BACKUP physically_set_write_protect_tab; amverify BACKUP

Re: Unloading tapes when task done ?
I Beleive you are in error. 4mm dds simply have the head stop spinning, the tape is still wrapped around in the mechanism. The DLT I have does not unload at all, unless specifically directed to. Maybe you can show me where u got your information from ? Maybe i can find the quantum docs that say 'dont do that'.

Re: DLT
Sorry if this subject is off topic but can you use a 40/80 DLT tape in a 35/70 DLT tape drive. Although we'd only be using it as a 35/70 tape. no problem to write on DLT IV tapes with a DLT 7000 drive
Re: Unloading tapes when task done ?
Maybe they can OPT-OUT of the feature ... It's just as easy for someone to opt-in and do their own tape operations when Amanda is done. Amanda will currently support both camps -- unload it when done vs. leave it alone. Why add more complexity? We already have too many options (and lots of other things on the TODO list). btw, what do u mean each operation. ... I meant amdump and amflush. John R.

Re: Still having problems with ufsdump returning 3...
Hi! I'm still having problems with ufsdump returning error code three, thus causing the dumps to fail. ... ? sendbackup: index tee cannot write [Broken pipe] | DUMP: Broken pipe | DUMP: The ENTIRE dump is aborted. ? index returned 1 sendbackup: error [/usr/sbin/ufsdump returned 3] You're looking at the wrong end of the pipe. The messages imply the server side shut things down, which broke the pipe and filtered back to the clients as bad news (there was nowhere to shove their data). One scenerio would be running out of tape (or getting a tape error) while doing a direct to tape backup. The server would shut down its side in that case and let the client fend for itself.

Its not healthy for the tape. Does that happen with a DLT tape, how about the DDS tapes. I'd have to assume that the DLT, which I know nothing about, shares such a feature with which nearly all other drives, including professional vcr's, that has a timeout of a minute or so, and, like the DDS drives I have, does a backout of the loading mechanism thereby removing the tape from contact with the scanner drum, usually with one supply or takeup spindle braked, and shuts the head drum down at the same time. The drive then gradually cools to match its resting temps and the tape is mostly protected and not subjected to the internal heat rise the drive does when its active. I do not consider the roughly 80 degree temps my tapes have when I eject the magazine as being that hard on the tape if the tape is not in motion. I'd love to see the tapes stored and used at or slightly below 50 degrees F, and 50% relative humidity as the tape is many times less abrasive then. Some TV stations have even gone so far as to store their tapes in a small room adjacent to the control room which is maintained in the 40 degree and 40% range. Everyting lasts longer, a lot longer. The tape makers themselves recommend it too, and have data to show that a tape used and stored at 90/90 for temp and RH, is not just marginally more abrasive, but dozens of times more abrasive. That effect was brought home to me many years ago when a headwheel failed in a now old 2 broadcast vtr. The wheel had over 7000 hours of runtime on it, and the failure was in a rotary transformer. We sent it back for repair. It was re-installed and ran till something over 9000 runtime hours was used and it was worn out. That headwheel came with a 200 hour prorated warranty as it had soft tips. No, I didn't forget a decimal there. The machine was in a precipitron clean, dry, cold room. Under more usual conditions I've seen them fail in 125 hours. But we don't have those conditions inside the typical computers case, not by a long shot. I would NOT like a live tape to be left in the drive for long periods of time. Who knows when a power failure will hit, who knows when the drive will go awol. An unloaded tape, immediately after backup, is safe from other folks, as well as the server, writing onto it. I'd consider that a problem only in those drives like older QIC's, that leave everything engaged for long periods of time, thereby denting the drive rollers etc. -- Cheers, Gene AMD K6-III@500mhz 320M Athlon1600XP@1400mhz 512M 98.7+% setiathome rank, not too shabby for a hillbilly
Re: A few interesting problems (tapeless, interactive restores, etc)
First off, for reasons beyond the scope of this email, my AMANDA server has no tape device. I am sending all backups to the holding disk. We also have a large IBM tape library running ADSM that I would like to incorporate into my AMANDA backup strategy. ... Sounds like a perfect setup for the tapeio code in 2.4.3 (now in beta test, but the tapeio stuff has been stable for a long time). You would set up a disk area to emulate a tape, then use the chg-multi tape changer to move the data back and forth with your ADSM system. The current (2.4.3 beta) chg-multi has a posteject hook to a script you provide that could move the date into ADSM. It would be easy to add a preload step to do the other direction (don't know why I didn't think of doing that when I did posteject). A) I need a way of asking AMANDA, If I want foo file from 3/20/2000 on machine bar, which dump 'directories' will I need? ... The tapeio code would take care of this. Amanda would tell you you needed tapes A, B and C, which would map directly to your ADSM areas. If you don't go with tapeio, then I think amadmin config find ... is what you'll want. You may also need to be a bit sneaky about the data motion to ADSM and leave the names and holding disk directories behind, but truncate the files to zero length, or, worst case, truncate them to just their 32 KByte header. I'm pretty sure that would fool amrecover sufficiently into using them (obviously, you'd have to reload the rest of the data before turning the restore completely loose). Greg Mohney John R.

Re: sendbackup with dumplevel 0 takes a while to startup :-{
according to the tar docs, the --listed-incremental will check on the files listed in the file if the incremental file is not empty. I suppose the listed-incremental file got filled during the sendsize proceedure?! No. It got filled by the previous sendbackup run (e.g. yesterday). And, FYI, for a level 0 (full) dump, the listed incremental file comes from /dev/null, i.e. it is used, but empty. During the sendbackup step, tar is apparently going through and checking the list, as no data is being transmitted while tar is doing this check. I'm not sure exactly how tar does this. You'd have to look at their code or ask them. I'd be surprised if it completely lost it for 30 minutes, though. Is this how its suppose to work for a level 0 dump? ( 4 hours (wall-time) sendsize, ~4hours (wall-time) incremental check, and finally the transfer of the data ( i suppose longer that 4 hours )) ... Probably true. Is this how it will work with other level dumps ( with the exception of the transfer of data step) ? Yes. Except Amanda may also request a third estimate one level higher than the previous one if it might be time to bump (you can control this with the bump* parameters). You might want to consider using an alternate size calculation tool called calcsize. It's not well supported, and does not handle exclusion lists, but does all the estimates at the same time so you might gain quite a bit of time that way. If you want to go this route, let me know and I'll find the postings from a while back about turning it back on. /gat John R. Jackson, Technical Software Specialist, [EMAIL PROTECTED]

In the FAQ off of the main www.amanda.org page: http://amanda.sourceforge.net/fom-serve/cache/293.html You might also want to search the mailing list archives for references to Onstream.

Amrestore and tar
Greetings I am having a problem with amrestore with backups made using gnutar. I hope this is not in some doc I have missed or in the list archives, I have spent a lot of time looking. Lets say the server has the following hhd config: FilesystemSize Used Avail Use% Mounted on /dev/sda8 251M 110M 127M 47% / /dev/sda1 53M 3.8M 46M 8% /boot /dev/sda6 3.1G 568M 2.4G 19% /home /dev/sda5 3.1G 1.7G 1.2G 57% /usr /dev/sda7 251M 123M 115M 52% /var So I have a entry in disklist for the following (for the host) client/root-tar client/boot user-tar client/home user-tar client/usr user-tar client/var user-tar Note: thay all use gtar (although confusing, the archives seem to indicate gnutar is a better option than dump with 2.4.x kernals) Also since amanda uses the --one-file-system option with gnutar I have one entry per partition. Now if amanda backs up more that one partition on the tape in one run, I could have /boot / /home say, on one tape, and in this order. Now to restore I do the following on the client ssh amandaserver amrestore -p /dev/nst0 host host.tar The first entry in the achive is extracted (/boot) and amrestore stops. Now, if I were to say use the following in an attempt to get the / archive: ssh amandaserver amrestore -p /dev/nst0 host / host.tar Once again /boot is extracted and amrestore stops once done. So then, without having to extract the entire archive without amrestore, how can I get the / partition from the tape as /boot is found first, matches the diskname (at least in terms of regular expressions), extracts and stops? Config is: amanda 2.4.2p2 tar 1.13.19 (client) and tar 1.13.25 (server) (BTW, will change all to 1.13.25 as I am still missing files with 1.13.19, ie on this host 823megs off 1.7gigs in usr was backed up :-( , clients with 1.13.25 seem to be fine) Regards Warren
