Hi,
We are facing a backup issue in one of our windows machine. backups are taken using symantec Netbackup tool. so we raised a SR with symantec and investigate the issue. we got the update from symantec team as Backup processes got hanged and vssadmin list writers also not shown any output. they concluded as this is purely windows issue you need to check with windows team.
anyone can help on this issue.
