I have a netapp filer & ndmp backups are configured for Voumes & qtrees on the filer . We run a monthly backup & weekly backup for same volumes . There are 20 volumes , however backup is not running for 1 volume in last few days though the backup (ndmp) used to run fine before . We are using Networker as our backup software but no issues were found from Backup/host side .
The strange fact is that backup for 19 volumes is running fine but not running for 1 volume at all .
Secondly root acess is used to access the volumes via Backup software to login into Netapp .
Thanks for the responses . We were able to solve the issue . The issue was that the Networker library as having the issues . First we reconfigured the library again . Then we tried to see byte count of tape writing via cl.i in Networker(nsrwatch) . C.LI was updating the byte count so we were now sure that data is writing .
Secondly , the size of the data to be backed up was very high & G.U.I of Networker wasn't updating . Hence the issue was fixed .
