Restore from multi streaming backup image

Hello,

I'm making a backup whith multiple streams. The file list of my policy is:

      NEW_STREAM

      /a

      NEW_STREAM

     /b

When I make backup all is correct, 2 jobs appears, one in drive 1 and the other in drive 2, making backup in parallel.

When I try to restore I make two differents restores (one for /a and one for /b) expecting that both of them run simultaneous. But until the first one no finish the second one don`t start.

it is possible to make a multi streaming restore? How?

 

Thank you very much for your help.

    Well, I've just backed up 2 separate streams of data to two tape drives, similar to above.

    Restore 1.

    I selected the data from both streams in the BAR gui.  One jobs started, loaded a tape into two different drives and restored the data from both tapes at the same time.

     Restore 2

    I selected one straem in the BAR gui and ran the restore.  A tape was loaded into a drive and the restore started.

    I then selected the other stream in the BAR gui and ran the restore.  A second job started off immediately and loaded a tape and started to restore.

    So, using both methods, I ran two restores from two separate tapes from the backup that was muti-streamed at the same time.

    If nothing else, this shows that it should work - if you could provide the details of what the '2nd' job is waiting on, would be one way forward.

    I'm sure someone will have seen this  before, I haven't so will have to ask a couple of questions.

    For the restore that is waiting, what are the exact details you see in activity monitor, hopefully this will give a clue as to why it is waiting.

    Also, what version of NBU, what OS is this running on.

    Than you very much. You are right! I have just tested it

     

    I don´t know what I did the other tests.

     

    Thanks!
