hard quota limit for the directory tree has been exceeded, NDMP cannot create a temporary
file and the restore operation fails.
• NDMP does not support the case-insensitivity property in a file system or a directory within a
file system and will not back up a file system with this property enabled. As a result, after
restoring a file system, the case-insensitivity property is not restored to directories on the file
system. This is the expected behavior. If case-insensitivity is required after a restore, you must
explicitly set the property on the parent folder of the restore location.
Configuring NDMP parameters on the cluster

the NDMP Servers in the cluster. To configure the parameters on the GUI, select Cluster Configuration
from the Navigator, and then select NDMP Backup. The NDMP Configuration Summary shows the
default values for the parameters. Click Modify to configure the parameters for your cluster on the
Configure NDMP dialog box.
