Can Exchange server backed up using NBU 7.6 (Master and agent)  be restored on  version 7.5 . ?

Will there be an issue with support ?

 

Thanks

If any new features in NBU 7.6 were used to write the backup, you will not be able to restore with 7.5.
Restores are supported the other way round.

What is the reason for this request?

Why would you want to use 7.5 to restore 7.6 backup?

I am setting up DR site for customer and backing up exchange (residing on VM ) using the SCR copy at DR. 

ESX 5.5 is supported only with 7.6.0.2 hence thats what I will have to install on DR NBU, however their prod NBU is at 7.5

I would ideally not want to touch their prod envt hence this question. 

My guess is in worst case scenario the restore might or might now work. However Symantec might not help troubleshoot in case of any issue with restore citing diff NBU version.

Chances are that restore will not work. From your last post, not even the backup.

It seems that the Master (on NBU 7.5) at Production site will need to backup a client at the DR site that is installed with NBU 7.6?  
This will not work and is not supported.
Client and/or media server cannot be at a higher version than the master server.
Only higher 'point patch' is supported.

Hi Marianne,

Dont think I mentioned the setup properly. 

 

Prod Site

NBU 7.5.0.4

Exchange - CCR .. ( Not being backed up)

*******************************

DR Site

NBU 7.6.0.2

Exchange - SCR . (Agent based backup)

*******************************

Customer wants to look at worst case scenario wherein Prod Site Exchange is down, DR site exchange is down along with the Netbackup. So only option will be to take the tapes from DR and import it into Prod NBU (7.5.0.4) and try to recover exchange which was backed up using 7.6

Hope this clarifies the setup and my query.

 

Thanks

Chances are very slim that restore will work and is definitely not supported by Symantec.
Restores are 'downward' compatibile.
