SLP issue

This issue has been solved. See solution.


Scenario :

We are replicating our backups from domain A to Domain B.(from newyork to australia)

We have data domain in our environment.

We are using SLP for this.on site b we have scripts that run 1 and 2 phase import every 5 mins

In the SLP,we have defined that first backup on site A goes to data domain on site A  and then then duplication to Site B data domain.

Yesterday,What I did I created  an SLP for only backup on site A and gives destination st unit as b-replication-stu.

backup was successfull.But was not showing in catalog on site B.

And when i run this similar backup from site A without slp and just st unit as b-replication-stu.It was successfull and showing in the catalog.

Why so?

FOR SLP:ONE copy needs to be on the surce domain?Is it a condition?

are you saying that you have configured the Data domain LSU in two different master server site A and Site B?

why you setup the phase  1 and 2  imports to run every 5 min?

what is the the status of import jobs?

Why so what?

You would probably be better using AIR for this scenario:

Agree A.I.R sounds ideal for what you are try to do. DD should now supoprt A.I.R function.

I  just wanna know whether slp can be trigerred if i have only use backup in slp.only backup( no duplication) .and the destination on this slp is storage unit of site B.Is it possible?

On site A:

SLP NAME:Replication a-b

for backup only.and st unit is st unit (disk pool) of site B.

Now when i run gets successfull.But I am unable to see my image ID in catalog on site B.

On the other side,if i dont use SLP and straight give st unit of site B in policy.It is completing successfully and is showing in catalog on site B.

Why this is the difference?

I am asking whether my slp can be used for only backup?

You could use an SLP only for backup yes.  However this is NOT recommended :

1.  It is confusing, people expect to see a 2nd copy ion the SLP config ...

2.  It is not what SLP was designed for, if you only want a backup, run a backup.

but when i am running slp only for a backup,It is completing successfully on site A.On THIS site we have a disk pool configured which is for site B.So this backup is going on disk pool on site B.(st unit is for site b)

Now what we have is that we have a import script which runs on site B which picks all the data which is sent to the disk pool in site b

but when i saw this in catalog on site B,It is not showing there.Why?

I have no idea, is the script working, can you import it manually using for example the GUI (just as a test, not as a solution)

we are using data domain (open storage)

Is NetBackup managing the script on Site B? If so, I think I may know what you're asking. But it sounds like Site B is not getting the right information via the script. And I'm sure you'll want to know the original client from which a particular backup was taken.

The catalog for the master server that takes the initial backup will contain the image information.  In your case, the Site A master server has the information relative to the backup in its catalog.  If you use an SLP to duplicate the data to disk storage at Site B, the information will remain in Site A's catalog.  When the Site B master server runs the script to import the data it should create the image information in its catalog.  If the master server is not running the script, then that would be why the catalog is not populating. 

If you want to be sure the catalog information is going to Site B you would be better off using AIR. Granted, importing the backup images should add entries into the catalog on Site B. But by using AIR it's all contained within NetBackup.

Hopefully, this helps.
