change order of hosts to be backed up

2006-05-31 Thread Dennis Ortsen

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

2006-05-31 Thread silpa kala
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

Not exactly 1/10 of the data, but some number for disklist
entries with total amount as close to 1/10 of the data
as possible.
If you got only 1 entry in your disklist, then there is
nothing to divide or spread.

Also the first time, Amanda tries to dump as much as
will fit on a tape.  It's only during the next runs, that
Amanda can schedule incrementals (lvl  0) instead of
a full dumps.  You will have to wait at least 1 cycle
before you notice the spread of level 0 over the cycle.


 
Please help me out in this. What parameters need to be

I still believe your notion of partial full is different
than that of Amanda.




If u provide the example with minimum configurations
or amanda.conf then that will be helpful.

There is dumporder, which can order dumps by of size, time, or 
bandwith, but not alfabetically.


And there is the dumptype option starttime where you can
delay the starttime of some DLE's/hosts.

It would help if you specified why you would like a specific order.

Are you trying to accomplish something like:

RE: Cluster backup

2006-05-31 Thread Paul Haldane
 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.  Then 
come on back with any questions you still have.

If I had to guess, I'd say that you had for example Server1 which has an IP
and also the VirtualA IP. 

In you disklist you have DLEs for both Server1 and VirtualA.

Amanda contacts Server1 to start an estimate/dump.
Amanda tries to contact VirtualA to do the same, but amandad is already
  running on that machine.

Sound like a possibility?

Sounds very reasonable.

I have been thinking about handling more than one amandad by
adding more than one amandad listening, each bound to only
one IP-number.

Asssuming you have two interfaces, or an alias to one interface:

   eth0  IP 192.168.0.1/24
   eth0:1IP 192.168.0.2/24

You can add some parameters in the xinetd.conf file for the amandad service:

   service amandad
   {
  id = amandad1 # give this entry a unique name
  bind = 192.168.0.1# bind to this IP-number
  ...rest of the params...
   }
   service amandad
  id = amandad2
  bind = 192.168.0.2# bind to the other IP-number
  ...
   }

I did not yet have time to test this out...
Any feedback welcome.

The above means that Amanda did not start up another dumper because
the holdingdisk had all space reserved by other dumpers.

When a dumper needs more diskspace on the holdingdisk than it reserved
in the beginning, it asks driver with a command RQ-MORE-DISK? Do you
see that string in the logfile?



Then the filesystem dump fails over an hour later:

driver: result time 17127.984 from dumper0: FAILED 01-00054 [data timeout]


I would have a look in the sendbackup.*.debug file on the client and
see if some warning/error message is in there, and verify that the
client was still running at that time.

Could this also be just another symptom of the problem described here:

http://wiki.zmanda.com/index.php/Amdump:_mesg_read:_Connection_reset_by_peer


Why does the data timeout occur over an hour after disk space becomes 
available?  The dtimeout parameter in amanda.conf is set to 1800.


I think it is because the datatimeout is not triggered by the diskspace
but by something else.

Re: Partial full backup configuration for amanda

2006-05-31 Thread silpa kala
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.

Regards,
silpakala








I seen the amstatus is showing

  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. 
 
 Not exactly 1/10 of the data, but some number for
 disklist
 entries with total amount as close to 1/10 of the
 data
 as possible.
 If you got only 1 entry in your disklist, then there
 is
 nothing to divide or spread.
 
 Also the first time, Amanda tries to dump as much as
 will fit on a tape.  It's only during the next runs,
 that
 Amanda can schedule incrementals (lvl  0) instead
 of
 a full dumps.  You will have to wait at least 1
 cycle
 before you notice the spread of level 0 over the
 cycle.
 
 
   
  Please help me out in this. What parameters need
 to be
  configured in amanda.conf file to perform partial
  full backup.
 
 I still believe your notion of partial full is
 different
 than that of Amanda.
 
 
  
  If u provide the example with minimum
 configurations
  or amanda.conf then that will be helpful.
 
 Example configurations are on the wiki:
 A minimal one:

 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.
 

NO, it is NOT proper for a Partial Full Backup

This is because, as others have already said,

  amanda does not do partial full backups


Each DLE receives either a full or an incremental backup.
