You first have to label a tape, and that label has to be unique too, even for a new tape (new means, labeled, but not yet used to backup). It's not a good scheme to label your tapes Monday-Friday, as you have already noticed. But if your really, really want to do want you intend to do (skip the monday tape), then you can lower your tapeycle by one (but keep the real amount of tapes). The tapecycle is the number of tapes that are active. If you have a tapecycle of 4 tapes, and you have 5 tapes, than you can feed amanda any tape of the last two tapes. Amanda will ask for the oldest one, but accepts the last-but-one too, but not one of the 4 most recently used tapes. Thanks for the feedback guys.

That would probably be correct. You gave amanda a value for the dumpcycle, normally considered as number of days. You also gave her a 'runspercycle' I assume. If 'dumpcycle' is 7, and 'runspercycle' is 5, then amanda knows she has to schedule so that in 7 days, but only 5 runs, she must do a full on each and every entry in the disklist within that 7 elapsed days, with only 5 runs to do it in. If you have a changer robot, so that amanda can use more than one tape, it might be helpfull when you have a makeup tuesday, to let her use a second tape by setting runtapes to 2 just for that tuesday run. If you have holding disk space enough to hold the backup, read those portions of the docs carefully, then it could have run on monday normally, and you could have flushed it first thing tuesday (to the mondays tape it was looking for) and all would be well again. OTOH, if you have the changer, why not just go ahead and leave the crontab entry alone let her do a monday backup even if it was a holiday? The acronym for amanda is Advanced Maryland Automatic Network Disk Archiver. Note the Automatic. If left to settle into a routine without any interference from us, amanda will, after a couple of dumpcycles to get things figured out, be as happy as can be. She doesn't take holidays off, doesn't ask for a raise or longer coffee breaks, what more could one ask? :-) -- Cheers, Gene There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

Annoying
Hi all, I am a cpio man, and am used to getting a backup to do what I want it to (IE flexible, without to many complications). This is why Amanda is irritating me at the moment. Earlier I had the problem where I was being ask for Monday's tape (Which was a public holiday and so didn't run). After seeking your advise, I realized that Amanda needed to run with Labels. I got a hold of Monday's tape which is held offsite in the attempt to keep Amanda happy with the idea of also running Tuesday backup afterwards. However when trying to backup (# amdump CLG), I am receiving the error: *** A TAPE ERROR OCCURRED: [tape_rdlabel: tape open: /dev/nsa1: Device not configured]. Some dumps may have been left in the holding disk. Run amflush to flush them to tape. The next tape Amanda expects to use is: MONDAY. I then tried to flush to tape (# amflush CLG) and get the error:*** A TAPE ERROR OCCURRED: [tape_rdlabel: tape open: /dev/nsa1: Device not configured]. Some dumps may have been left in the holding disk. Run amflush again to flush them to tape. The next tape Amanda expects to use is: MONDAY.

I found some references to such wrappers, but I've failed to find a good example of one, and what needs to be done on which machine (client/server). OK, you asked for it :-). Some notes on the following over-engineered, under-tested, script: * It has **NOT** been run in a full Amanda setup, other than what little I did to make sure syntax was right and the general flow worked. * The script uses **EXAMPLE** execution point functions (see the code). You **WILL** have to change it to do what you want (and remove what you don't). * There are definitions of the Amanda debug directory (e.g. /tmp/amanda) and path to GNU tar (on the client) in the first few lines that may need to be tweaked for your environment. * It is written in ksh (although now that I think about it, I probably could have used Perl). Hopefully the examples and your own shell coding experience will be sufficient to fit in what you need, but if you want some help, ask me offline. The idea is to install this on the client and build Amanda there using --with-gnutar=path-to-script. Then set up the disks you want to use this wrapper with GNU tar as the dump program in disklist and add execution point functions (see the code) to the script to do what you need. Note that the script doesn't have to actually use GNU tar -- that's just the trick to get Amanda to call it with a set of arguments that are easy to decipher. You can use a run_* function to use whatever dump program you want, as long as it generates an estimate to stdout that Amanda can parse and sends the actual dump image to stdout. Note also that compression is a separate step Amanda will tack on to the stdout of this script (or not). If you want to do your own compression, add it to the script and tell Amanda compress none. Then test it at least once :-). If you set the DEBUG environment variable to print (or echo -- same difference), the script will run but not execute anything (although you'll have to set up your own functions to follow the examples in the code). Here is a sample test line I used (using ksh as a login shell): DEBUG=print gtar-wrapper.ksh \ --directory /home/HomeAC \ --file - \ . Amanda will pass whatever you set in disklist as the --directory argument. To test estimates, change - to /dev/null for the --file argument. Amanda passes a mess of other parameters, but only --directory and --file are of interest to the script. If you do any significant argument processing, make sure you don't loose anything (see function do_home in the script). I think. :-) John R.

Re: Avg Dump Rate and Compression
There are a few more things to try. First, there may be an mt command to set the default compression for the drive--that will at least help make sure if you use some new tapes, they will get started with the correct compression. The tricky part is that some drives, such as 8mm, use the density to set the compression and ignore the compression command. You can usually get some ideas by looking at the output of mt status. Under Linux, the commands you want would be something like mt defcompress off and mt defdensity then the drive will (hopefully) use those settings by default when you load a new tape, and for some drives, may actually override what's on the tape that you load. I have sometimes put these commands into one of the system startup scripts, such as /etc/rc.d/rc.local on Linux. Second, some drives have dip switches that you can set to hard-disable compression. For example, I had a Sony DDS4 autoloader that had dip switches to do that. At least, the dip switches make it non-ambiguous what is going on. Third, some drives may have (usually Windows-based) firmware utilities that will let you set the settings of the drive, sort of like software dip switches. You would just need some Windows computer with a SCSI card in it, it wouldn't even have to be a good SCSI card just to send the commands to the drive as long as you have the right type of cable. The bad part is you have to disconnect the drive, possibly move it, and hook it up to the WIndows box. Worst case, maybe you could get some sort of SCSI adapter for a laptop with WIndows, such as PCMCIA, USB, Firewire, or even Paralllel to SCSI adapter. Fourth, some tape drives like AIT or AME (Mammoth) supposedly try to set the compression dynamically based on the data and don't care whatever you do to try to stop it--you would have to go to the manufacturer and look up the specs for the drive to find out if it does that. Lastly, when I have run into this problem, I usually have done this, but wonder if it could have caused problems: # load the tape mt compress off amrmtape config label amlabel config label If you're going to be doing this to a bunch of tapes in an autoloader, it probably would be easier to script the dd command that Gene described, because you just dump the header to a temp file and the script doesn't have to try to parse what's in the temp file to figure out what the tape should be called. Good luck! Gene Heskett wrote: The only way I know of to fix such a tape is: rewind it read out the label to a scratch file using dd rewind it again turn the compression off with mt -f device whatever turns it off dd that scratch file back to the tape using the non-rewinding device dd at least enough data from /dev/zero to force the drive to flush its buffers. This will force the drive to turn the header compression flag off and that tape will not be compressed again unless you turn compression back on. --jonathan

TL891 plus fibre channel question
I am currently trying to configure amanda for our department. The tape library we have is a Compaq TL891 with two tape drives and 26 storage slots. I have it connected via a Compaq fibre channel tape controller(FCTC) to a fedora linux box. I can view the status of the tape library with an mtx -f /dev/sg0 status. Contents of my /proc/scsi/scsi show that fedora sees both the tape changer and both drives. The drives appear to be accessible via /dev/st0, /dev/st1, /dev/nst0, and /dev/nst1 My question is this: I've reviewed the TAPE.CHANGERS documentation that is included with the amanda binaries. However it is not clear which changer configuration is best suited to this hardware. All I know is mtx commands that actually try to interact with the hardware confuse the FCTC to the point of needing to be rebooted. Mtx staus commands are ok, but I tried configuring the chg-zd-mtx changer portion of amanda and that kills it pretty quickly. If anyone has experience configuring amanda for this hardware, I'd appreciate any direction you could provide. Thank you.
