Re: help pls: Additional information
Hi all,
after some problems .. finally I managed to install and make run Amanda
using the rpms given with RedHat7.0
As you saw reading teh posts in this mailing list I had several
problems. Most of them were caused by my poor experience with backup
tools, but a couple of them were caused by the RedHat distribution. What
follows is a short review of the problems that I found ... I hope that
it can be helpful to some reader of this mailing list.
I installed the following 3 rpm files :
amanda-2.4.1p1-18.i386.rpm
amanda-client-2.4.1p1-18.i386.rpm
amanda-server-2.4.1p1-18.i386.rpm
using the command "rpm -i amanda"
The problems were :
1) the rpm files don't create a file amandad in /etc/xinetd.d, so you
have to create one :
#xinetd.d file = amandad#
# default: off
#
# description: Part of the Amanda server package
service amanda
{
socket_type = dgram
protocol= udp
wait= yes
user= operator
group = disk
server = /usr/lib/amanda/amandad
disable = no
}
after this you have to create an entry in hosts.allows as well ... I
added the following line on the server PC:
ALL: localhost 127.0.0.1 128.197.61.90
2) All the files are installed using the user "operator" ... the problem
is that his home directory is /root ... I strongly advice to create a
separate home directory for the user "operator", change the /etc/passwd
accordingly and move the file /root/.amandahosts to the newly created
directory, changing the permissions accrodingly.
3) Some of the files and directories needed by amanda are not created
upon installation of the rpm files and have to be created (you can
easily trace which file/directory is missing reading the output of
amcheck!!).
4) I used the following amandaidx amidxtape files :
#xinetd.d file = amandaidx#
# default: off
#
# description: Part of the Amanda server package
service amandaidx
{
socket_type = stream
protocol= tcp
wait= yes
user= operator
group = disk
server = /usr/lib/amanda/amindexd
disable = no
}
#xinetd.d file = amidxtape#
# default: off
#
# description: Part of the amanda server package
#
service amidxtape
{
socket_type = stream
protocol= tcp
wait= no
user= operator
group = disk
server = /usr/lib/amanda/amidxtaped
disable = no
}
I hope that this will help!!!

Amanda cannot cause hardware errors. It's a simple user level program. It can, however, exercise your system in ways that hadn't been tested before (e.g. streaming data to your tape) and in the process shake out a hardware problem. John R.

Re: nfs mounts
>I have amanada client with nfs mounts, does amanda backup >nfs mounts also. If it does is there a way to exlude it based on >file system type. You're asking the wrong question. Amanda does not back up anything. It runs some other program that does the backups. So it would depend on what program you told Amanda to use. However, all system dump programs (e.g. ufsdump, dump, vxdump) only do a single file system and would not cross into another file system, NFS mounted or not. If you use GNU tar, Amanda passes it the option to do the same thing, i.e. not cross into a file system other than the one it starts out in. So unless you use GNU tar and explicitly tell it to back up one of those NFS mount points, I'd say they will be ignored. >Shakaib Sayyid John R.

After you send inetd a HUP (and wait a minute), is there anything of interest in /var/adm/messages? Do you actually have a user "amanda" (or whatever) defined? Is it local (/etc/passwd) or are you one of those silly NIS people? :-) If none of this helps, the next thing I'd try is starting a truss on inetd itself and making a connection that does not work, then look at that output. >- John John R.

Separate "estimator programs" from "backup programs". As it is now, if I
decide to use tar for my backups, it will also be used for the
estimation phase (which is where my problem is: estimation of
incrementals). But tar may not be estimating correctly in my case,
although it may be perfect in backing up.
So the idea is to give us the chance to write our own "estimator
function": a script that gets a filename, a date and/or a backup level
(and perhaps also other parameters) as input and gives a boolean as
output ("yes, it should be backed up" or "no, it shouldn't"). This
script will have a "default" code in it: if tar is used, then tar is
invoked to determine if the file should be backed up, if dump is used,
then dump is invoked for the estimation, otherwise...a custom code
should go here. If the user decides to put custom code in there, he
should comment the default coding. He can then check the file's inodes,
ctimes, the phase of the moon or whatever else he deems aproppriate to
decide whether it should be backed up or not, in the given incremental
level and/or date.
The way it is now, I have to change tar itself, writing a wrapper around
it, taking into account who started it, whether it was for estimation,
backup, or restore etc. This makes the task more formiddable than it
already is (for unskilled programmers like me).
By the way: Why shouldn't I be able to use dump for the estimations and
tar for the backups (and vice-versa)? This solution (assuming it is one,
i.e. assuming that dump estimates correctly where tar does not), is less
general than the above, but should take you only another parameter in
amanda.conf and some case checking to implement with the existing code.

I first tried it as follows: I told AMANDA to backup the SAMBA shares that a SAMBA server made available on the backup server. The SAMBA server got those shares from as mounted vfat partitions. This is where SAMBA came into play. It did not work - incrementals were almost as big as full backups. Then I said myself "why have this SAMBA stuff at all? Just mount the vfat partitions and tell AMANDA to use tar and backup the mount point directory". This did not work either for the same reason.

Now I want you to understand that I have a problem (the above one) and I cannot find a solution with AMANDA. When I read the "AMANDA chapter" on backupcentral.com, stating that "Recent versions can also use SAMBA to back up Microsoft Windows (95/98/NT/2000)-based hosts", I thought "Fine! That's the _ultimate_ solution!". It turned out that the above statement may be technically correct, but somewhat misleading to the unaware: when you use SAMBA for the vfat partitions of your dual boot system, it does not work. It seems that either you have to run Windows on those partitions the same time that you run Linux and AMANDA to back them up (which is impossible on a dual boot system...eh, OK, maybe VMware could solve this "detail") or run the SMB shares that you want to backup on ext2, not vfat, filesystems (also impossible for a dual boot system, as long as Windows does not run on ext2 ;-)). It does not work even if you abandon SAMBA and just try to backup a vfat directory. The problem is estimating the incrementals and has more to do with tar, vfat, the kernel, or whatever, than AMANDA itself but I insist on refining the above statement by pointing out this - admittedly very special - case, where it is just not true. Believe me, I will be very happy to find out that this refinement is not necessary and that I was wrong after all ;-) -- Regards Chris Karakas Don´t waste your cpu time - crack rc5: http://www.distributed.net

My amamda server is an Intel box which dual-boots NT and Linux Red hat 6.2. /dev/hda1 is the NT C: boot partition /dev/hda5 is the NT D: extended partition However, I have the mounted RO on the linux side because I often use them with VMWare from Linux, effectively multi-booting my box. ;) Mounted RO, Gnu tar sees them as /mnt/doscb and /mnt/dosdb. I could have accessed them via samba instead, since my VMWare appears to my Linux personality as a completely separate system with its own Hostname and IP Address. I played with this and it does work, but I don't use it because I rarely leave VMWare running for long periods of time. (It consumes half my ram and degrades my native Linux JBuilder application, which also consumes half my ram. Running them both causes my machine to start swapping heavily, and since I spend most of my time doing Java development, I launch VMWare only when I need to do excel stuff.) You could try a VMWare-hosted smbtar backup. -- Joi Ellis [EMAIL PROTECTED], http://www.visi.com/~gyles19/
Woody problems
Hello, We have an office full of machines mostly running Storm Linux (Debian Potato based). Our Amanda server is running Amanda version 2.4.1p1. Several people in the office have upgraded their machines to Debian Woody and Amanda no longer backs them up. An example of the error message in the daily mail report is as follows: /-- nheron /home/nheron lev 0 FAILED [/sbin/dump returned 1] sendbackup: start [nheron:/home/nheron level 0] sendbackup: info BACKUP=/sbin/dump sendbackup: info RECOVER_CMD=/bin/gzip -dc |/sbin/restore -f... - sendbackup: info COMPRESS_SUFFIX=.gz sendbackup: info end ? You can't update the dumpdates file when dumping a subdirectory sendbackup: error [/sbin/dump returned 1] \ The clients are running amanda-client version 2.4.1p1-12 and dump version 0.4b20-1. I notice the dump version is different between Woody and Potato (0.4b16-1) but even downgrading to the Potato version didn't help. There are lots of strange things that happen when upgrading to Woody but everything seems to be running fine now. There is probably something that should be running that is not, however, and I don't have much experience running Amanda and don't know where else to look to solve the problem.

>... Several people in the office have upgraded their machines to >Debian Woody and Amanda no longer backs them up. An example of the error >message in the daily mail report is as follows: >... >? You can't update the dumpdates file when dumping a subdirectory As has been discussed in this mailing list in the past few days, some new versions of Linux dump do not allow subdirectories of mount points to be backed up. The latest adds the feature back, but only partially and not enough for general Amanda use. According to Bernhard Erdmann just yesterday: Linux' dump 0.4b20 still allows dumping of subdirectories. However, it does not allow the "u" flag (update) with subdirs of partitions anymore, because it would break /etc/dumpdates' syntax. Read dump's ChangeLog carefully. Amanda calls dump with "u" if you set "record yes" in amanda.conf. Probably you do not want to do full dumps every day, so you might switch to tar for subdirectories. Why are you trying to do that in the first place? Dump is usually just used for entire file systems. If you want to do subdirectories, you usually switch to GNU tar. >Owain John R.

I'm using samba-backups with an exclude-statement (specified in the disklist-file). As far as I read from the files in /tmp/amanda the exlusion is only used when backuping, not when estimating. Bug or feature? (BTW: amanda-2.4.2) Regards, Lipo -- Roland E. Lipovits Vienna, Austria

What do you mean? It works for me. Or are you talking about backing
up vfat partitions while running GNU/Linux, in which case Samba isn't
used at all; all you need is GNU tar?
Which has just given me yet another idea for you to try: set up your
GNU/Linux box as a Samba server, and run your backups pretending the
GNU/Linux box is actually running MS-Windows, i.e., arrange for it to
be backed up through Samba. This will use Samba's mechanism of
creating incrementals, which are quite different from those of GNU
tar, and might get you around the problems you're facing with vfat,
GNU tar, the Linux kernel or whatever :-)

So will I :-)

That's exactly what the `sendsize' program is. You'll even find hooks
for a `calcsize' program in there. Of course, you can modify it so as
to call whatever other program you want, but using the wrapper script
suggested by JJ is far easier, at least before the DUMPER API is
implemented.
Note that you don't have to replace GNU tar with the script: just
configure Amanda so that it uses your replacement script as if it were
GNU tar and you're done.

I recall having introduced a bug in 2.4.2-beta1 while introducing the
ability to verify labels (which also tests whether you're using a
non-rewinding device). The bug has been corrected in 2.4.2 final.

Re: Error on Screen
Hi, i assume you are ussing Linux, correct? What kernel-version ? For me that looks like a problem in the kernel-driver for your scsi-controler, because the so-called SCB's are datastructures used to transmit the scsi-commands from the kernel to the controler. And the messages say some strange things, especialy the negative values in the second line should never never occure I would ask one of the scsi-kernel-gurus for your controler for the reason of this error.
