Feeling lazy, do I have to upgrade to 2.5.0p2?
Amanda group, I recently purchased the new Quantum LTO-3 library. I also purchased a server that unfortunately works initially with Debian's Testing installation which defaults to 2.5.0p2 of Amanda-server/client. I can communicate with the 20 amanda-clients on 2.4.4 with the amanda-server 2.5.0p2 amcheck, heck I am even able to dump/tar. I've had many successful test backups so far, but don't want to be surprised with a weird problem later on. I quickly glanced at the documentation for incompatibility issues 2.4.4 vs 2.5.0p2, but found none. Thanks!
planner: disk xxx:/, estimate of level N failed
In the last few days I've started seeing a couple of messages like the above in the NOTES section of my daily reports. The DLEs in question do get backed up, but it is a level 0 each night. Originally it was just one server, now it is two. Both are running 2.5.0p2-1 Debian etch packages, one is x86, the other is arm. A third amd64 machine is still working fine so far. The appearance of the errors may have coincided with package updates, but I'm not sure (although they have been 2.5.x for awhile). Since I've been running Amanda for years, my first thought was just to check the /tmp/amanda/*debug files, but was surprised to find that those files don't exist on any of the 2.5.0 machines, all that is in /tmp/amanda are selfcheck*exclude, sendbackup*exclude, and sendsize*exclude files. It's not critical, theses are my home machines and I have the space to handle nightly level 0s, but I had been considering an upgrade of my work machines to 2.5 from 2.4.5 and am now concerned that this might be a bug that needs fixing before I upgrade. The estimate error may be just a Debian package thing, either in the Amanda package or possibly in tar, but evidently the debug files have been missing longer than the estimate error. Any debug suggestions? Frank -- Frank Smith [EMAIL PROTECTED] Sr. Systems Administrator Voice: 512-374-4673 Hoover's Online Fax: 512-374-4501

How about extracting the raw dump file from the tape on to aphrodite. amrestore has options (I always have to look them up) to pull it off. If it is gzip'ped, expand it and check whether the file(1) cmd sees it as a dump archive and whether the old restore can recover from it. Probably a table of contents would be sufficient. Or extract a few files. Then transfer it (the archive) to bablefish and ensure it can restore from the archive. If you can only do it from bablefish, perhaps the new dump has options to make old archives. Or maybe the new restore can be compiled and added to the old OS. Finally, you should be able to do an amrecover from bablefish rather than on the server. > > >When directed to do so, did you manually load the correct tape > >and rewind it before typeing "y"? > > Yep...

Re: Ran a Tapetype for LTO-3 if anyone is interested
I am unsure why my tape is half the speed but almost 40 gigs more than the
others in the Amanda Wiki. My tapes are Imation Ultrium LTO 3 tapes. Maybe
they are a little longer?
Amtapetype was executred with the device /dev/st0, I do not think this
would make a difference, or can it? Also SCSI generic support was not
available at the time.
Now that I have everything from the barcode reader working to the tapes
labeled, I will run the tapetype again. I also have SCSI generic enabled
and plan to run tapetype with the /dev/nst0 device.
I will cut and paste the complete console message after the job is
complete if it comes out different. I will use the same tape that I used
to run the original tapetype too.
After all, I too am wondering why I got more space but half the speed. I'd
rather have the reverse.

On each client that is using tar for dumping you need
/etc/amandadates, owned by client's "amandauser/group",
rw by user&group
If your server is also a client, then you need that file.
amandahosts should be ".amandahosts" and it should not
be in /etc, but in the home directory of amandauser.
BTW in your line:
> # sudo ls /etc/ama*
Do you really need to sudo to execute ls on the /etc dir?
Particularly if you are already running as root ('# ' prompt).

Perhaps an Amanda changer support problem?
Hello, We are using Amanda 2.5.0p2 to backup data to a PowerVault 136T with 2 LTO2 drives. We are running this on OpenBSD 3.9 and we are using CHG-CHIO as the changer. It works fine without barcode reader support. However we recently implemented barcode reader support in the OS and now we are attempting to modify the changer script to use that support so that the external tape labels are read to locate the required tape. The changer successfully reports to Amanda that it is 'searchable' but some commands are not responding to it like the tapechanger documentation indicates it will. These commands respond appropriately: amtape config update (will execute 'tpchanger -label') amtape config label "labelstr"(will execute 'tpchanger -search') The following commands DO NOT respond. The documentation indicates they should respond. amtape config taper (does not try 'tpchanger -search') amcheck config(does not try 'tpchanger -search') amlabel config "labelstr" slot # (does not try 'tpchanger -label') It seems that even though 'searchable' is set to 1, 'searchlabel' is not being set to 1 within Amanda. Can anyone suggest what we may be missing or overlookinging in our attempts? Or is this a bug in the Amanda code? Thank-you in advance for any suggestions or advice.

Is this the only disklist item you'd have? Also, how frequently will you be running backups? Basically, I found that Amanda with DVD-Rs was too much trouble for backing up my home system. Rather, I run dump manually. Make a holding area, and use dump with a tape size of just slightly less than the DVD-R size. Tell dump to generate manifests and quick file access data. Then, all you have to do is burn each dump file to a DVD-R in pre-prepared mode (check man growisofs for details on this) and burn/store the index/QFA data somewhere. Once you have that burnt, restores are easy. You just tell restore to restore from your DVD device. When it asks for tape number X, you insert DVD X and it does its thing. It works quite well and prevent having to juggle all the information that Amanda is going to keep about your filesystems. -- Ross Vandegrift [EMAIL PROTECTED] "The good Christian should beware of mathematicians, and all those who make empty prophecies.

Cygwin amanda client behind firewall
I am running 2.4.5P1 server on a Solaris host. I have a cygwin Win2003 client that sites behind a firewall. Can someone explain the IP address 0.0.0.0:PORTNUM. This seems to be causing me problems in trying to get my amanda server to talk to the Win2003 client. I have one firewall setting that that allows all IP on our subnet to get to any host and to any service on the LAN. The firewall setting works because I can run netcat from the amanda server to the 100080 UDP port of the cygwin client behind the firewall and I get the proper response. But when I run amcheck I am getting the timed out message. ./amcheck -c daily cygwinclient Amanda Backup Client Hosts Check WARNING: cygwinclient: selfcheck request timed out. Host down? Client check: 1 host checked in 30.025 seconds, 1 problem found I believe it has to do with the 0.0.0.0:PORTNUMBER that is used by amanda to communicate with the clients. I am not exactly sure what or how this works but I know on a previous cygwin client, outside of the firewall that used zonealarm, I had to trust the IP address 0.0.0.0. Is this something that I should be able to set on a the firewall? I am kind of lost at this point. Thanks Robert _ Robert P.

Yes, indeed, although I have to admit I've not done as much testing of
restores yet, as I should have done. Nor have I yet added networked backups.

I created a set of 21 vtapes. I created one tapetype, HARD-DISK based on what
I had read:
define tapetype HARD-DISK {
comment "WD 120GB drive hdb6"
lbl-templ "/usr/local/etc/amanda/Daily/3hole.ps"
# length 4100 mbytes # will burn to DVD
}
but then, amongst the documentation somewhere I came across these examples,
too:
define tapetype CD650 {
comment "CD-R 650MB sized vtape"
length 681984000 bytes
filemark 4 Kbytes
}
define tapetype CD700 {
comment "CD-R 700MB sized vtape"
length 73728 bytes
filemark 4 Kbytes
}
define tapetype DVD47 {
comment "A 4.7 Gbyte DVD-Sized vtape"
length 4000 mbytes
filemark 4 Kbytes
}
define tapetype DVD85 {
comment "A 8.5 GB DVD double layer"
length 8000 mbytes #approximately - exact value not found
filemark 4 Kbytes
}
My dumptype settings are:
define dumptype global {
comment "Global definitions"
index yes
# record no
tape_splitsize 400 Mb
# split_diskbuffer"/tmp/dumps"
fallback_splitsize 100m
maxpromoteday 1
}
define dumptype root-tar {
global
program "GNUTAR"
}
define dumptype user-tar-span {
root-tar
tape_splitsize 400Mb
comment "tape-spanning user partitions dumped with tar"
I back up three distinct areas, two of which are graphic and audio, so they
are backed up without compression. The third area is /home, and a Level 0 of
that does require spanning. The backup is broken down, and the vtapes can be
burned to DVD.
As I said, I'm pretty new to this, and no kind of expert, but if you want any
more info, please ask.

Dealing more gracefully with tape overruns
We run AMANDA for many years with the same taper and the time comes with more and more users until one tape per day is sometimes not enough. :-/ We don't have any changer and often one tape is enough. So I would like a mode where AMANDA would decide it is not possible to have everything on one tape *but* would not stop dumping and would go on on the holding disk. Then the autoflush mode would flush everything the day after or a manual flush could be done on a separate tape. The problem is that when AMANDA notices that there is not enough space on tape, it stops with messages such as: minou.info.enstb.org /var lev 0 FAILED [dumps too big, 180301 KB, but no incremental estimate] minou.info.enstb.org /home lev 0 FAILED [dumps too big, 3309778 KB, but no incremental estimate] pei.info.enstb.org /mnt/bonbonne/subversion_backups lev 0 FAILED [dumps too big, 1414910 KB, but cannot incremental dump new disk] minou.info.enstb.org /export/bouteille lev 2 FAILED [dumps way too big, 4632849 KB, must skip incremental dumps] I'd like to have incremental and even level 0 dumps on the holding disk, where I have a lot of space. I've played recently with maxdumpsize -1 # Maximum number of bytes the planner will schedule # for a run (default: runtapes * tape_length). but it doesn't help since it says it can decide to dump more than a tape but it fails later with the same messages than above. So, is there an obvious way to deal with the not-so-frequent overrun we encounter? If not, what about adding a new strategy with a mode such as: dump-on-holding-disk-if-degraded-mode yes Should not be to difficult to implement. I will try also to play with the reserve keyword next night with, for example, reserve 50 % for full backups. reserve number Default: 100. The part of holding-disk space that should be reserved for incremental backups if no tape is available, expressed as a percentage of the available holding-disk space (0-100). By default, when there is no tape to write to, degraded mode (incremental) backups will be performed to the holding disk. If full backups should also be allowed in this case, the amount of holding disk space reserved for incrementals should be lowered. But if it works, why this static allocation between incremental and full backups? Another approach: what about also a mode with runtapes > 1 without any changer, assuming that the user will use amflush later?

Not direct to DVD, but perhaps a with 2 step process. I believe at least one poster to the list, ?Anne Wilson?, may be using such a setup. Perhaps she/they will comment. Amanda has the ability to use a hard disk as a "virtual tape" using the "File:Driver". The vtapes (as opposed to ptapes :) are headed by a single directory. A collection of these can be thought of as "slots" in a changer and rotated through automatically using a changer script just like a a physical changer. You must specify a size for your vtapes, thus if you specify something slightly less than your recordable size, you can then transfer an entire vtape to a corresponding dvd. As you seem to be talking about backing up a single directory tree (/home), I would suggest that you read more about amanda's unique scheduling of dumps and dump levels. Combined with amanda's refusal to append dumps to an active tape will be different than your NetBackup experience. It may influence your choice of backup solutions. -- Jon H.

Re: Hints on using amverify
amverify will read the tape, gunzip if gzipped, and use the list option of restore/dump (which does not compare to disk contents). (Really one can't compare to disk contents because they might have changed, although a procedure of checking all and noting matches/mismatches with ctime/mtime would be useful.) In assessing how useful this is, it's helpful to think about the kinds of errors that can happen: * failure to read bits for the tape (media error, signaled on read) * silently getting the wrong bits from the tape (i.e., not the ones that were written, but with no error indication) * dump not dumping some files that it should * dump producing the wrong bits on the client * gzip producing the wrong bits * changes in the bits from the client to the holding disk * changes from the holding disk to the tape * misconfigurations that fail to dump filesystems that should be backed up (amverify-like programs can't detect this of course). I have seen the first two failures actually happen, and the last is of course common. The others seem not to happen much. A key point is the use of gzip, which has a CRC. So if you read a file and the CRC is ok, then it is likely that the output of gzip (in my case, on clients) was correctly transferred across the net, to the holding disk, to the tape, and then back off the tape. Without gzip, you'll get error indications if the metadata is unreadable, but the data isn't checked. So silent corruption may not be detected. I run amverify once a week (and amdump 5 times). This is a tradeoff between tape wear and quality control - if it works essentially every time once a week, I'm pretty sure that things are generally ok. Probably it should run with p=0.2 every night, to avoid checking the same tapes. -- Greg Troxel <[EMAIL PROTECTED]> pgpxkgzcd098q.pgp Description: PGP signature

Re: Problems with new Amanda release (2.5.0p2): amcheck not reporting tape errors via e-mail
Hi, This problem was fixed after the 2.5.0p2 release, use CVS or the latest 2.5.0p2 snapshot from http://www.iro.umontreal.ca/~martinea/amanda/ Jean-Louis Jon LaBadie wrote: On Tue, Jul 11, 2006 at 07:03:01PM -0500, [EMAIL PROTECTED] wrote: I recently upgraded the first of our Amanda installations to 2.5.0p2 ] and found an unwelcome surprise: amcheck no longer reports tape problems via e-mail from an amcheck run out of the Amanda user's crontab file. A similar (same?) bug was reported by J Tibbet in May and again on June 30. Supposedly it was corrected, so a newer snapshot may be in order. If not, Paul B, on July 3 posted a couple of lines of patch you could apply to amcheck.c.

backing up to DVD-Rs
Hi, I'm sure this question has been asked many times before, but I couldn't see it in the Faq-O-Matic. Bascially I have a 30GB directory (/home) and 50 4.7GB DVD-Rs. Is there any support in Amanda for backing up to DVD-Rs? Actually, the only thing I'm looking for is the capability to divide the 30GB into 4.7GB chunks, or slightly smaller to fit on a 4.7GB ext2 loopback file which can be burned to DVD. I tried using 'tar --multi-volume', which sort of does what I want, but it's interactive, not compressed, and difficult to manage indexes. Thanks, Laurence PS: The silly thing is, (and not "ironic" before anyone thinks it is, because it is not), I maintain a Veritas NetBackup Enterprise solution at work, but I have absolutely _zero_ chance of taking my HD's in and backing up there...

Wow. You got 440 Gbyte on a 400 Gbyte tape???
But your speed is about half what others got...
Compare this to:

I'm curious about the cause these significant differences!

You may or may not be familiar with traditional unix backup facilites, dump and restore and some filesystem specific variants, like ufsdump/ufsrestore, xfsdump/xfsrestore, etc. When asked to, and if run by root, they record the date and time and level of the dumps in a file /etc/dumpdates. This file then can be used by dump in the future to decide what needs backing up at various dump levels. Tar does not have this built-in, so amanda mimics it in /etc/amandates. -- Jon H.

Communication between the chunker and amandad
Hi, Please help me out in this problem. I seen the socket connection between the chunker and amandad. What is purpose of the socket? Actually I understood that backup data send by the amandad(client) and received by the dumper(server)through the data port. Is it true? How the dumper will send the backup data to the chunker? I understood that chunker is introduced in 2.5 version for new features splitsize. Suppose if i didn't configure for this parameters, eventhough chunker is playing as an important role. Why the dumper funda is moved to chunker. Taper is creating the Shared Memory. Why it is necessary? Please clarify me these doubts. Thanks & Regards, Silpakala __ Do You Yahoo!? Tired of spam? Yahoo!
