Sorry, it's not available for download atm. But I hear it wasn't that hard to customize the Knoppix CD. It's based on Debian, so the Debian package management tools should work for adding stuff to it and removeing unneeded things. Perhaps amanda client was even already included in the latest version of the original Knoppix distribution, not sure...

One of my colleagues has built a bootable rescue CD based on the Knoppix Gnu/Linux distribution (see www.knoppix.net if you don't know Knoppix). His CD includes an amanda client besides our usual tools and goodies. I have just recently used this CD to clone two of our machines, testing the disaster recovery in case of a complate hard disk failure. Steps are: - booting from the rescue CD - setting up networking and starting sshd to be able to work comfortably from my workstation ;-) - partitioning the hard disk, setting up swap, creating file systems - mounting the root partition somewhere like /mnt/target - recovering the root partition using amrecover via the network - mounting the remaining partitions into the recovered root partition's mount points - recovering the remaining partitions - setting up tmp on the target partition (since /tmp is normally excluded from our backups), giving it the correct permissions - chrooting into /mnt/target and making the system bootable (quite easy with grub) - rebooting and testing the system. Works great if the new machine is identical to the old one. In my case, I ran into a (small) problem because the clone machines were only Pentium I while the original machine's kernel was built for Pentium II and higher. However, since Knoppix (and thus my colleagues's rescue CD) are based on Debian, "apt-get install"-ing an appropriate kernel wasn't very hard :-) The most tedious part of this procedure was changing the tapes (only a single DLT drive here). I should really take a look at the file: driver some time...

How did you solve it? I have seen the same error message a few times (on Debian 3.0, too, but I don't think that matters). AFAIK (someone please correct me if I'm wrong!) this "error" is the result of dumping an active (mounted) filesystem on which files are being changed during the dump run. fsck checks I have run afterwards (on the umounted fs) have shown no errors. The incident still is very annoying since "the ENTIRE dump is aborted" leaving me without a backup for this DLE. My solution was to switch from dump to gnutar. I still get messages files that have changed during the read operation etc. but these do not cause the whole DLE to fail.

IMO you are experiencing perfectly normal behaviour: - amcheck -m doesn't find any errors, thus is keeping quiet. You will only get mail from amcheck -m if it has encountered some errors: "Nothing is printed, but mail is sent if any errors are detected." (amcheck manpage) - amdump runs the backup and sends out its usual report about the run. Kind regards, Martin.

Yes, occurs here sometimes as well: planner announces a level 2 backup for a disk list entry, but a level 0 (full) dump is done instead. If I understand amanda correctly, planner WOULD bump this disk list entry's level to 2 (instead of staying at level 1, since the bump threshold has been reached), but the DLE is due for a full (level 0) dump, so this is what really gets done. (Anybody please correct me if I'm wrong.) A little confusing perhaps, but otherwise normal behaviour. Greetings, Martin.

What is the > non-compressed tape device called? I have no in-depth experience with FreeBSD, but I have not heard of a distinction on compression in the device file. Perhaps this is mixed up with the distinction of the rewinding/non-rewinding device? We have a FreeBSD 4.1-RELEASE machine here (that will soon be replaced) which is using hardware compression (we'll change that, of course) on a DLT drive by calling the following wrapper script from cron: #!/bin/sh /usr/bin/mt comp on $HOME/sbin/amdump ToplinkDaily /usr/bin/mt rewoffl tapedev used is the normal non-rewinding scsi tape: tapedev "/dev/nrsa0" Hope this helps, Martin.

And if something else needs bandwidth at the same time, the total bandwidth will be divided up between them. IMO the netusage parameter is most useful if you want to _guarantee_ a certain free bandwidth for other traffic on the net (time-critical applications like Voice-over-IP come to mind) by forcing amanda to _always_ stay below the netusage limit. However (if I understand the docs correctly), amanda will honor this limit no matter if there _is_ any other traffic, so most of the time you might end up leaving bandwidth unused. Greetings, Martin

According to the amanda manpage, the default value for netusage is 300 Kbps, which IMO is far too low for today's LAN technologies.

I certainly wouldn't AFAIR the machine had been quite busy otherwise at the time of that tapetype run. The backup last night (my first on this setup without hardware compression) achieved an average tape write rate of 344.6 KByte/s which is ok IMO.

However, I had once tried a "compress-best" on the server's own paritions and it took about 5 times longer than the usual. Now I'm back to compress-fast and happy with it. Greetings, Martin.

Hardware compression is now switched off (both with the drive's internal dip switch and the mt utility option), and I have rerun tapetype after making sure the tape's internal information on this was cleared (following Gene's instructions - thanks!).

How was that influenced by the estimate of 4GByte I gave with the -e option? I had left out this option the last time I ran tapetype. - The filemark seems to be unusually high. Can this be correct? Does this mean I'm wasting over 4 MBytes between two files on tape? Is this something that can be changed or is it a property of the drive? - The speed is not that high, but might well be correct.

Using an absolute path for the exclude-list file in the dumptype definition as I did, would then lead to the exclusion af ANY directory named "mac" on ANY filesystem that uses this dumptype?

The solution seems to use a _relative_ definition of the exclude-list file as well: [amanda.conf] exclude-list ".amanda-exclude.gtar" and [/disk-c1/martin/.amanda-exclude.gtar] ./mac I'll try this and see if it works.

[amanda 2.4.2p2] tar exclude list not working
Hello fellow amanda users, I have been using amanda for some time, successfully backing up whole filsystems with dump. Now I'm trying to back up only parts of one (large) filesystem using gnutar and the exclude-list feature. The relevant config snippets are as follows (machine lissy is server and client in one, config name is "lissyDaily1"): [/etc/amanda/lissyDaily1/disklist] lissy /disk-c1/martin comp-user-tar [/etc/amanda/lissyDaily1/amanda.conf] ... define dumptype comp-user-tar { program "GNUTAR" comment "partitions dumped with tar" options compress-fast, index exclude list "/etc/amanda/exclude.gtar" priority medium } [/etc/amanda/exclude.gtar] /disk-c1/martin/mac The results are not as I had expected. amanda seems to ignore the exclude list and tries to backup the whole filesystem below "/disk-c1/martin". Since this includes the rather large subdirectory "/disk-c1/martin/mac", the backup doesn't fit on the tape and fails: [lissyDaily1 AMANDA MAIL REPORT FOR September 21, 2002] FAILURE AND STRANGE DUMP SUMMARY: lissy /disk-c1/martin lev 1 FAILED [dump larger than tape, skipping incremental] The /var/log/amanda/lissyDaily1/amdump.1 log file show the estimated backup size as: got result for host lissy disk /disk-c1/martin: 0 -> 23243790K, 1 -> 23093150K, -1 -> -1K which is (give or take a few KB) the size of the whole /disk-c1/martin hierarchy INCLUDING the /disk-c1/martin/mac subdirectory: $ du -sk /disk-c1/martin /disk-c1/martin/mac 23298740/disk-c1/martin 23133416/disk-c1/martin/mac $ So, /disk-c1/martin EXCLUDING /disk-c1/martin/mac should be only 165324KB or about 160MBytes which would fit perfectly on the tape.
