Starting a new tape - per partition
Hi, I have a 120 gig server that I need to back up. I want to do /boot ; / ; and /var on one tape, and /home on a second. I have chg-zd-mtx as my autoloader driver. Here's the question. If I configured my disklist file like this: bigserver/boot always-full bigserver / always-full bigserver /var always-full bigserver /home always-full When Amanda is done with /boot, /, and /var say there is only 10gig left on tape 1. Will amanda automatically 'see' the lack of space and autoload a new tape before starting on /home? Or should I create another config directory like this: /etc/amanda/bgserver-Daily-roots /etc/amanda/bgserver=Daily-home If this is the right idea, I also need to know if I just copy ALL of the files (except disklists of course) from one directory to the other so that they match? Here's a list of files that would be listed in one of the above pseudo-directories. Which ones need to be copied accross to the other config directory? Assume I have been only running backups on bgserver-Daily-roots. These files are now already existing in that directory. amanda.conf mtx-changer-access mtx-changer-clean mtx-changer.conf mtx-changer-barcodes mtx-changer-slot tapelist tapelist.amlabel tapelist.yesterday disklist Now say I add a 80 gig home directory to the server. How should I configure Amanda to start a new tape when it gets to this new remote partition? Thanks a million! Scott Phelps
About Linus's condemnation of Dump
I just stumbled over an email from Linus stating the following:
snip snip
Note that dump simply won't work reliably at all even in 2.4.x: the buffer
cache and the page cache (where all the actual data is) are not
coherent. This is only going to get even worse in 2.5.x, when the
directories are moved into the page cache as well.
So anybody who depends on dump getting backups right is already playing
russian rulette with their backups. It's not at all guaranteed to get the
right results - you may end up having stale data in the buffer cache that
ends up being backed up.
Dump was a stupid program in the first place. Leave it behind.
end snip
Read whole thing here:
http://www.cs.helsinki.fi/linux/linux-kernel/2001-16/1175.html
Anyhoo, I find myself currently using the Reiser filesystem, and I am now
considering backing up critical config files and directories on my servers
with tar and rebuilding them from scratch using XFS since that filesystem has
a working version of dump ('xfsdump').
Any comments, advice? (Does Amanda even work with xfsdump/xfsrestore?
Thanks,

Re: amcheck: Permission Denied
I fixed it. I needed execute permissions on the devices. Thanks.
New prob: Disk Offline? error
OK, I am running my first dump. amcheck returns 0 errors now, but heres a new problem I need help with. Can anybody tell me why I am getting these errors? The only clue I have is that /boot was not mounted.

Does amanda need a shell?
Hi, I am a new subscriber and a new user of Amanda. I'm just getting it set up and, I was reading through my new copy of Curtis Preston's book when I came to the point where I need to issue the command: # su amanda -c amlabel DailySet-01 VOL1 slot 1 The problem is that nothing happens because (correct me if I'm wrong) su -c will not work without that user having a shell account. I have all of my config files set up, and i am really anxious to start using it. Could somebody shed some light on how to use Amanda's commands? Thanks, Scott

This gives Amanda permission to do its stuff. There's good information here... http://people.web.psi.ch/bearpark/mirror/frankenlinux.com/guides/amandaintr o.html ...that discusses the Amanda user, and specific permissions that the Amanda user needs to have in order to operate effectively, as well as a good deal of additional advice. You can also check the docs directory of the source for more information. Thank you so much! That site is awesome and I fixed my problem. -- Scott
