Vaulting and Storage Lifecycle Policies

Created: 08 Nov 2012 • Updated: 11 Nov 2012 | 14 comments
This issue has been solved. See solution.

Is there *any* way to use these together.  Here is my scenario:

I need to use SLPs to replicate MSDP data from our primary DC to an offsite DC.  That is working well.  However, I want to batch up writing older MSDP images from disk to tape.  Vault has always worked for this functionality *very* nicely.

So I configured a vault to start rolling images off the MSDP to tape - only to receive the "images failed: Already duplicated" message. 

Is there any way to use vault in this manner?

Thanks,

-Mike-

Should work.

In host properties > master > global attributes, what is teh 'max backup copies' set to.  If this is only = to the number of copies you have after te SLP is run, vault won't be 'allowed' to make any more.

"Max Backup Copies = 4" - and the images only appear to have a single copy (I assume that's because the SLP is doing a Replication to the DR site - a separate domain):

Hmm, just tested it - I get the same thing ...

I'll have a play about see what I can work out

Changed the vault policy aroung, but still same error.

Doesn't look like it works after all - anything I have duplicated with SLP is ignored by vault (well, rejected).  I'm a bit surprised, but then, I'd never tried it before.  

I then ran a backup to the same STU that the SLP used, but using a regular policy and vault copied that image fine.

As a work around if you get a list of the backupid, put these as a list in a file and use this with the bpduplicate command to  duplcate them 'manualy'

Yes - that's not a bad idea.  I was hoping that there was some more elegant way to accomplish this - vault does a pretty good job of "batching" the images so that the tape drives get used efficiently.  I'm not sure how well a manual "bpduplicate" is going to compare... but I think I'll try it out.

If anyone else has any ideas, please keep them coming!

Thanks.

Edit: I missed the part that you wanted to do this in the source nbu domain, not the target domain. The following is now somewhat irrelevant.

Sounds like another case of SLP not wanting to let go of its toys.

To achieve a "batching" effect (more or less), you could try tweaking LIFECYCLE_PARAMETERS at the target nbu domain. Specifically these entries:

DUPLICATION_SESSION_INTERVAL_MINUTES = Minutes_value (default 5, min 1)
Change this to some big number, so it doesn't check as often. You don't need it to anyway according to your needs.

MIN_GB_SIZE_PER_DUPLICATION_JOB = GB_value (default 7)
Change this to something huge.

MAX_GB_SIZE_PER_DUPLICATION_JOB = GB_value (default 25)
Change this to something huge again; larger than the min gb one.

MAX_MINUTES_TIL_FORCE_SMALL_DUPLICATION_JOB = Minutes_value (default 30)
Change this to very long periods, so you give the min gb param enough time to fill up (possibly reaching max gb); effectively batching more images per duplication job.

It's easy to do ...

Here is a list of images I put into a file (call the bidfile)

 

womble_1351156009
womble_1351148274
womble_1351146905
womble_1351098562
womble_1351098070
womble_1351098024
womble_1351075851
womble_1351070382

I put these backupids into a file /tmp/imagelist

 I will duplicate to a STU called womble-4mm-robot-tl4-0
The bpduplicate command creates the copy (Bidfile = list of images to duplicate)

bpduplicate -Bidfile /tmp/filelist -dp NetBackup -dstunit womble-4mm-robot-tl4-0
 

... and it is as simple as that

I know it is pretty easy to use bpduplicate - it's the management of the duplications that vault is particularly good at.  If I just get a list of images for a day and duplicate the bid file it throws the duplications to a single tape drive.  I'd rather not get mired in the management of splitting up bid files into chunks and sending the individual broken-up files to bpduplicate.

I was hoping I was missing something easy and obvious...

Just a thought - and i cannot test it at the moment - plus you will have to think about any other consequences ... but if you set the vault profile to make 2 copies what happens? Does it skip one but do the other and so give you what you want?

As i say - total theory but maybe worth a try

OK, multiple tests later ...

Configured a basic disk STU and ran SLP that backs up to sp1 and duplicates to sp2 (sp1 and 2 are both advanced disk stu).  Once completed 

I then ran vault to copy this again to 'basic_disk' and it worked ...

... ok - so not sure why things aren't working for you, but at least we have shown that vault can duplicate an SLP image (as you can see above, 3 fragments, 1 is SLP backup, 2 is SLP duplication, 3 is vault duplication ).
 
I did get a simlar error with what I have now decided was an 'invalid' test - trying to get vault to duplicate another copy of the image on the same stu as either the SLP backup or the SLP duplication (sp1 or sp2)
 
Not sure why you are getting this error, as you are going from disk to tape - I'll dig round a bit more ...
 
Perhaps I'm missing something obvious - let me know if you see it   :0)

SOLUTION

Yeah - it's really rather strange.  I wonder if it has something to do with the AIR I have configured... although I don't know why it would.

mph999's picture

Ahh, one MAJOR thing I forgot to mention ...

I could only play about with ad disk pools / basic_disk etc ... as I have no AIR setup.

This is the closest I could get.

The only conclustion I can reach at the moment, is that this is a limitation in the NBU - but I can't find anyone else reporting the same thing.

I've asked Marianne to have a look, she may very possibly know something I don't ....

Sorry guys - was a misconfig in the vault duplication settings.  I got that sorted out and now I'm vaulting data successfully.

A related question, though - my 1st vault created 4 duplication jobs:

#1 - 14TB - media server 1

#2 - 4.5TB - media server 2

#3 - 2.4TB - media server 3

#4 - 2.0TB - media server 2

Each of these media servers has 3xLTO5 drives attached.  How do I get Vault to break up these jobs into somewhat smaller ones to stream to *all* my tape drives on each media server?  I'd get through things more quickly with more numerous, smaller jobs.

Thanks!
