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..

It is almost happening to every backup I run.. sometimes it fails after 10 hours and sometimes after 4 hours.. its pretty random..

I had looked at the above Tech docs while one of them says double the path of the volume which mighy be wrong which in my case isnt the issue and the second one points to the incremental backup issue when no files have been changed.
I dont run incremental backup on my netapp filers only full..

Refer to the NAS event log/syslog and look for related error messages. I don't think Netbackup is the one to blame here.
