Changing the socket buffer size for large restores
When you attempt to restore a large number of files or a large amount of data, the restore may run very slow. If you encounter this sort of behavior, you should change the socket buffer size on the NetBackup media server and the NetBackup destination client. The following procedures explain how to set this socket buffer size.
For more information about changing the socket buffer size, see the NetBackup OpsCenter Performance Tuning Guide.
