Troubleshoot Microsoft Azure Backup Server database operation failures by checking SQL Server, DPMDB health, connectivity, storage and logs.
01

Capture the exact error

Record the MABS error ID, SQL error, timestamp and affected operation. Avoid repeatedly retrying a failing operation without checking the cause.

02

Check SQL Server health

Verify SQL Server service state, database status, disk space, SQL error logs and recent maintenance activity.

03

Check DPMDB state

Confirm the DPM database is online and accessible. Review SQL Server logs for corruption, recovery or I/O errors.

04

Check connectivity

Validate that the MABS server can reach the SQL instance and that the expected SQL service and instance configuration are available.

05

Check storage

Database and transaction log volumes require sufficient free space and healthy storage. Investigate latency or disk errors before expanding capacity.

06

Recovery validation

After correcting the SQL or storage issue, test a safe MABS operation and confirm protection groups and jobs can access the database.
