Issue:

File Server fails to create snapshot though it is enabled on NDMP software:

As seen on the file server (Data mover) log:

NDMP: 4: Session 142 (thread ndmp142) NdmpdData::startBackup, SnapSure creation for backup failed

 

Cause:

Snapsure not enabled on file server.

As seen on the parameters of the file server(Data mover):

param config cs_external_ip=<>
param cifs djAddAdminToLg=1
param quota policy=filesize
param ip reflect=0
param nfsv4 domain=<>
param cifs srvpwd.updtMinutes=720

(Snapsure is missing)

 

Change:

Backup from Snapshot was enabled on the NDMP software but not on the File server (Data Mover).

 

Resolution:

Enable Snapsure on the Data mover using the server_param command (This will not require a reboot).

server_param server_2 -facility NDMP -modify snapsure -value 1
