    Hi,

    I have recently configured our celerra for NDMP backups (9_SP8a)

    There will be 3 Sublients for each of the 3 volumes. I have set it to 4 readers, but as i understand it multiple readers may not supported.....

    The Storage Policy has multiple device streams, 2 enabled and the TL has 2 tape drives

     

    But if i run a sinlge subclient, it only uses one of the tape drives???

    Is there soemthing i'm missing?

     

    Will a subclient only write to a single drive?

     

    Thanks

    Mike

    Do you have backup from snapshot checked?

    My NS480 only has 4 available readers.  one stream (file system) can only write to 1 drive at a time. 

    If you put the 3 file systems in the same subclient you should be able to get 3 readers going at the same time to 3 seperate drives.
