On running a backup of SIMS using the SIMS plugin on ESE, you may encounter an error similar to the following: "Warning: The database check for CAPITA database 'master' completed with warnings: Could not execute DBCC CHECK for database 'master': The database could not be exclusively locked to perform the operation."
The database that is impacted may vary between master, SIMS, FMS, etc. Sometimes multiple databases are affected.
This is not an indication of backup failure, only a warning that Redstor's system cannot check for database corruption as part of the backup.
To address this, first check if it is possible to manually run the DBCC check within SQL. If this is also not possible, it indicates that the error is simply Redstor's system warning users about an issue with either SQL itself or third-party software.
