backup Exec 11d

Hi Folks,

have just upgraded the LTO drive to LTO2 on the file server and updated the backup exec to 11d from version 10. Ever since doing this the backup speeds have dropped. Its taking over 40hours to backup 400G. My gut feeling is that the folder permissions are all over the place and this is what is slowing up the tape backup, i guess my question is could the permissions have this much effect on the tape backup speeds. I have updated all the tape drivers ect…

Thanks
