Backup of numerous small sized files using NDMP
Environment details: We have a master server and 5 media servers. OS is Windows 2008 R2 and NB 188.8.131.52 version is installed on these servers.
The output of tpautoconf for an NDMP client is as shown:
Connecting to host "edc-fs2" as user "edc-fs2"...

Host supports 3-way backup/restore
We have 8 drives dedicated for the NDMP backups. We also have 8 streams running in parallel.
Scenario:We have an NDMP share which has numerous small sized files and folders to be backed up due to which the backups are not completing in time and is over running during the business hours.
Question: Is there any way within the NDMP which can be implemented so that the backup window for the share hosting numerous small sized files can be reduced?
