Controlling vault - number of duplication jobs created?

Created: 12 Nov 2012 • Updated: 13 Nov 2012 | 5 comments
This issue has been solved. See solution.

I've recently configured vaults to roll data off of my MSDPs.  I have 3 appliances each with a MSDP and 3 physical tape drives attached via fibrechannel.  My first vault that I ran only launched 4 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.  So my vault only made use of 4 of the 9 attached drives.  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.

Is this type of control even possible?

Thanks in advance!

hi,

 

What are the Retenction Period of the images, netbackup vatult batch up the jobs based on the Retenction periods..

Please check the below T/N

http://www.symantec.com/business/support/index?pag...

to comeout of the sitaution and to make use of all Drives you need to create a  Multiple vault profiles 

for example:-

you have 100 Images having the Retenction Level 1 and using the media server as Media1 
(it general way it will create only one dupliate job as all images retenction is same)

so create a 3 vault profiles..and devide all 100 images based on Client name or policy name. 

these 3 profies will start 3 jobs and start using all avaliable 3 tape drives..

reffer the below tech Note:-

There has to be a way to configure this, no?

So I tested - created 3 vault jobs (1 for each media server).  The 1st vault (media server 1) I kicked off and it generated a *single* duplication job - 1708 images, 13.2TB.

Any other ideas?

Vault batching process is generally a built-in algorithm that we can't see, but as I understand they are batched in a way that minimizes the number of mount/unmount tapes. This is to say, using criteria such as media server and tapeID.

There is no known config files to adjust how you can batch it your way, but here is one technote that can be used to maximize your tape drive usage. Never have I tried it before.. you might want to test and let us know the result  :P

Ha!  They *did* create a way to control this part of vault.  I touched that file and now I am using *all* 9 drives.  Easy as that...

Thanks everyone for your assistance/ideas!

hi Elanmbx,

creating Vault profiles based on media servers does not help us in this case..

hear is what we have:-

1) 3 Media servers each with 3 tape drives (Total 9 Drives) 

2) Multiple clients with Multiple policies

( i assume 90 Clients with 30 Policies, each media server is having 10 policies and 30 clients for example)

creating 3 vault profiles is enough but image selection crieatria is based on Client or Policy.

senario 1:-

Profile 1 should inculde 1-10 Client from media serves 1, another 1-10 clients from second media sever and more 1-10 clients from last media server)

   > when you trigger this Vault job, it will create 3 jobs and occupies First drive form each media server.

Profile 2:- should include the 11-20 clients from media serves 1, another 11-20 clients from second media sever and more 11-20 clients from last media server

 > when you trigger this Vault job, it will create 3 jobs and occupies second drive form each media server.

Profile 3:-should include the 21-30 clients from media serves 1, another 21-30 clients from second media sever and more 11-20 clients from last media server

 > when you trigger this Vault job, it will create 3 jobs and occupies third drive form each media server.

 

you can start all 3 Profiles at same time, and they will occupy alll 9 Drives.

disadvantage:- when even we end the New client , we need to update the Vault profile also with the new Client name.

 

Senairo 2:-

in this we are divideing  the profiles based on Policies

Profile 1 should inculde 1-3 Policies from media serves 1, another 1-3 Policies from second media sever and more 1-3 Policies from last media server)

 

   > when you trigger this Vault job, it will create 3 jobs and occupies First drive form each media server.

Profile 2:- should include the 4-6 Policies from media serves 1, another 4-6 Policies from second media sever and more 4-6 Policies from last media server

 > when you trigger this Vault job, it will create 3 jobs and occupies second drive form each media server.

Profile 3:-should include the 7-10 Policies from media serves 1, another 7-10 Policies from second media sever and more 7-10 Policies from last media server

 > when you trigger this Vault job, it will create 3 jobs and occupies third drive form each media server.

Disadvantage :- when even we add the New policy we need to update the Vault profile with the new policy name.

 

even though both have minimum disadvantages,  i am sure they will help to occupy all avalaible drives. but its just increase one more step in new clients adding.. i.e adding to Vault profile..but that is not a big deal i belive..

 

let me know how it works for you ..
