change order of hosts to be backed up
Hi all, I'm using AMANDA 2.4.5 I've got a configuration question. I wasn't able to find a similar question with Google. I thought I'd try it on the list. I've got a disklist with a few DLE's in it. At the start of an amdump, AMANDA asks the clients for an estimate. When the server has received all the estimates, the planner starts doing it's work. What I'm interested in, is there any way to specify the exact order in the disklist for the DLE's to be backed up? For example: I have hosts mars venus and jupiter. In alphabetical order that would be: jupiter mars venus Now, what if I wasn't able to use a holding disk for parallel dumping (which means all DLE's are dumped sequentially) and I wanted host venus to be backed up first. Is there any way I can achieve this? Using a holding disk is an option offcourse, but what if I should be able to manage without a holding disk if I could only change the order the hosts are backed up. What can I do to achieve that? Thanks in advance, Dennis
Partial full backup configuration for amanda
Hi, I need some clarification on the usage of the amanda. What parameters need to be congfigured for the partial full backup i.e.,the full backup is divided into according to the dumpcycle and runspercycle. We configured dumpcycle 10 days runspercycle 10 Suppose this is the case, the full backup is divided into 10 parts. That means per day 1/10 of data is to be backed up. But, Instead of Partial full backup ,full backup is happening. Please help me out in this. What parameters need to be configured in amanda.conf file to perform partial full backup. If u provide the example with minimum configurations or amanda.conf then that will be helpful. Thanks Regards, Silpakala __ Do You Yahoo!? Tired of spam? Yahoo!

RE: Cluster backup
From: Nicola Mauri Sent: 31 May 2006 11:38 We are constantly encountering strange errors whith DLEs that refer to cluster virtual addresses. virtualA /apps/a lev 0 FAILED [data timeout] virtualB /apps/b RESULTS MISSING The disklist contains: node1 /etc full# Physical node 1 node2 /etc full# Physical node 2 virtualA /apps/afull# virtual address A virtualB /apps/bfull# virtual address B Error messages are not predictable and may change every day. They completely disappear if - in the disklist file - we replace the virtual address with the node's physical address which is running the service (and is currently mounting the shared partition we need to backup). Obviously, services and partitions might be relocated to another cluster node, so this approach won't work. I guess this happens because amanda server treats node1, virtualA and virtualB like three distinct hosts, whereas in some situations thay may refer to a single physical host, with a single amanda client instance responding. Can someone suggest how to solve this issues and how to configure Amanda to backup a cluster environment? We had similar behaviour with machines using virtual IP addresses which we eventually tracked down to inconsistent netmasks. Taking cyrus1 as an example ... [EMAIL PROTECTED] amanda]# ifconfig -a eth0 Link encap:Ethernet HWaddr 00:11:85:E7:40:75 inet addr:128.240.233.72 Bcast:128.240.255.255 Mask:255.255.0.0 eth0:1Link encap:Ethernet HWaddr 00:11:85:E7:40:75 inet addr:128.240.233.238 Bcast:128.240.233.255 Mask:255.255.255.0 (note difference in netmasks - eth0 is configured via DHCP, eth0:1 is configured statically). When Amanda server (ucsbs2 - also on 128.240.233.x) sends request to cyrus1 the reply comes back to ucsbs2 from cyrus (which is the address configured on eth0:1). I guess this is because the system sees eth0:1 as being more specific. Of course the Amanda server just drops the reply as it know that it didn't ask cyrus for anything. Making the netmasks consistent resulted in replies coming back from the main interface. Of course this doesn't help you as you want replies from the primary machine address for some DLEs and from the floating address for others. One suggestion that we had before we realised the issue was the netmask was to use chbind http://www.solucorp.qc.ca/miscprj/s_context.hc?s1=2s2=6s3=3s4=0full=0prjstate=1nodoc=0 or the interface (aka bind) option in xinetd to run multiple instances of the amanda client each responding on a different address (whether that will actually cause the responses to come from the right IP address I don't know).

Using amanda as it's meant to be used means giving up on the traditional *nix thinking about scheduling backups. You let amanda schedule fulls and incrementals, not you. Also, looking at the amanda.conf you posted, there are some fundamental errors. 'dumpcycle 0' forces amanda to do a full dump (level 0) every time you run 'amdump'. Also, tapecycle must be = dumpcycle. Stop. Read the documentation. Understand it. Run more test dumps.

Re: Partial full backup configuration for amanda
Hi, Thanks for this information. I gone through the all the threads related to the Partial Full backup configuration for amanda. Partial full backup is happening based on the DLE entries instead of memory occupied for all DLEs.That means If one DLE happens to contain 50% of all data, then one day Amanda must do all that complete DLE at once (and probably not schedule anything else for a full dump). Amanda will not divide the DLE itself. I seen sometime back amstatus is showing the keyword PARTIAL. Is it referring to Partial Full bakup. I forgot what configuration was done. Please check whether the following configuration is proper for Partial Full backup. Ex : Amanda.conf - dumpcycle 4 days runspercycle 4 disklist - sda path user-tar 50% sda0 path user-tar 20% sda1 path user-tar 10% sda2 path user-tar 20% sda is backed up 1 day, sda0 is done 2nd day, sda1 is backed up 3rd day, sda2 is backed up 4th day. After 4 days it will perform the full backup.Is it true. Is there any other configuration parameters is required to perform the partial full backup. I have little confusion whether skip-full, skip-incr or strategy parameters need to be enabled for the partial full backup.Otherwise only dumpcycle and runspercycle is enough. Thanks in advance.
