Hi,
Yesterday I repalced by LTO5 tape drives with LTO6 drives to take advatage of the higher storage capacity and evet since I have done that I am getting very slow speeds while backing up my NDMP data on my Netapp filer.
Earlier I use to get decent speeds of 120 Mb/Sec and now its like a max of 80 Mb/Sec if I am lucky and my backups keep failing with the same error message always which is..
===============

NDMP backup failure(99)
================
It is almost happening to every backup I run.. sometimes it fails after 10 hours and sometimes after 4 hours.. its pretty random..
Any Help?
Thanks
