NDMP Backup failing

Your error is the following:

0,51216,134,134,31,1427980889898,122724,139941325879040,0:,56:ndmp_data_connect failed, status = 23 (NDMP_CONNECT_ERR),28:NdmpDataSideNas::DataConnect,1

Which is the same as the one I solved over at:  https://www-secure.symantec.com/connect/forums/ndmp-backup-error-ndmpdataconnectv3-failed#comment-10915881

Here is a partial quote of the relevant information, adjust for your usage.

"

Port 2859 is within the default range for SERVER_PORT_WINDOW, which is 1025-5000, this range is used as random to open a server for other devices to connect to without keeping it at a constant port that can be attacked.

Per the info "ndmp_data_connect failed, status = 23 (NDMP_CONNECT_ERR)"

Your filer attempted to connect to 157.253.77.49 port 2859 and failed.

Please ensure that both software and hardware firewalls allow this filer to connect to that address on the TCP bidirectional port range 1025-5000"

Per our firewall documentation: http://www.symantec.com/docs/TECH136090

"The SERVER_PORT_WINDOW is used inbound from the filer to the media server for remote NDMP and can also be used for efficient catalog file (TIR data) movement with local and 3-way NDMP. "
