All,

 

Here is a little background for this question, we have a couple of NETAPP
filers that host a significant amount of data, I perform 3-way NDMP
backups on the filers currently, and there is no direct attached drive.
There were some files that need to be restored that were on tape, but were
not in the snapshots.

 

I had to restore one (1) folder and two (2) small files, this took 20
hours, I understand that it has to go through the images 2 times, once to
restore the folder and once to restore the files.  As thinking if I could
split up the streams the images would be split up and would reduce the
restore time.

 

If I am out in left field please let me know, suggestions would be much
appreciated.

 

Regards,
