Hi, Any parameters available in netbackup to control the number of concurrent restores per client.
it seems it is 1 by default.
Thanks,

What do you have for "maximum jobs per client" for the master or media server? If '1' that might be the problem.

Sorry, I am not sure how it became an "Accepted solution"
Max Jobs / client is kept at 25.

I thought that you meant the second job was queued for execution. Both jobs actually starting is another situation.

Since both jobs were active and already at "begin reading" stage, it means that the restore process was handed off to bptm on the media server.
Activity Monitor will show the bptm PID next to each "begin reading" entry.
You will need to look at bptm log on the media server to see what each bptm process is doing.
Level 0 log will probably not have sufficient info.
I would personally try level 3 log (Veritas Support will ask for level 5).
One more thing:
I see the following in the Data Domain Best Practice White Paper:
... “limit I/O streams per volume,” is set within a given disk pool....
This setting on the DD will limit max amount of read and write streams.
If this max limit has been reached, then maybe bpdm log on the media server will display appropriate message/entry received from DD, but this is a wild guess.
I think that DD logs may be more appropriate if this is the case.

Can we have multiple restore jobs running for different clients in parallel which were backed up on to same tape storage?

Yes.
They must be submitted at roughly the same time though.
