Netapp Filer NAS and NDMP backup
i have a customer having a 10 TB of NAS data ( File server with lots of small files) backup via Fc to LTO5 drives.We have changed the daily backup type to differential but the backup size seem to be very close to the full backup size.
Is there a best approach to backup huge data i multiple stream via NDMP backup ? Any new feature on Netbackup 7.5 which i can use?
Currently using Netbackup 6.5.4 and intended to upgrade to 7.5 latest version .
