Applies to

  • Snapcenter 4.3.X and higher
  • Snapcenter Plug-in for SQL Server [SCSQL] 4.3.X and higher

Issue

SnapCenter reports backup as successful up to version 4.4, even though SCSQL is unable to quiesce the SQL database and the snapshot operation creation is skipped, not backing up any databases and with no snapshots created on the storage.

SnapCenter 4.5 and higher fail the backup.

Underlying errors seen are:

  • SmSQL_<JOB_ID>.log
