This issue occurs if the Volume backup contains large number of Include\Excludes. All the Excludes are sent to NETAPP Filer as string value in variable "MULTI_SUBTREE_NAMES". If the string length goes beyond 1024 bytes than NETAPP Filer is unable to process this selection and hence the job fails. 

Run a SGMON debug and NETAPP Filer NDMPD debug to confirm if the string value of "MULTI_SUBTREE_NAMES" is getting truncated.

Workaround

Reduce the number of exclude path so that the string value for the variable "MULTI_SUBTREE_NAMES" does not go beyond 1024 bytes.

Please contact NETAPP support for details regarding this limit of 1024 bytes for the "MULTI_SUBTREE_NAMES" variable.
