How to Fix SQL Server Database in Recovery Mode?
Summary: This blog discusses the common causes behind the ‘SQL Server database stuck in recovery mode’ issue. Also, it describes how to troubleshoot and fix the issue. If the recovery process fails to bring the database online, try using an SQL recovery tool to regain access to the database – without prolonged downtime.
When restarting SQL Server or services after SQL database shutdown, server crash, or database corruption, the database automatically goes into ‘recovering’ state. The database becomes online after completion of the recovery process. However, if the database is taking too long to recover, it is important to know why the database is stuck in recovery.
What Causes SQL Server Database Stuck in Recovery Mode?
You can check SQL Server error log to know the cause behind the database stuck in RECOVERY mode issue. Common causes behind the issue includes:
- You might be restoring the database from full, differential, and log backups with the NORECOVERY option enabled, but RECOVERY is not specified during the last restore.
- As per MSDN, transaction log can fill when a database is in recovery. SQL Server stops all the running transactions until the log storage is freed, slowing down the database recovery. Several Virtual Log Files (VLFs) in a transaction log can also slow down the recovery process.
- The recovery process might stop if your database is damaged or have some sort of corruption.
Troubleshooting the ‘SQL Server Database in Recovery Mode’ Issue
Following are some simple troubleshooting tips to resolve the SQL Server database in recovery mode issue:
Tip 1 – Restore Database with RECOVERY
Note: Running ‘RESTORE with Recovery’ will make the database go through the same recovery steps again. Avoid this option if you have a large database.
Execute the following query to bring your database back online:
|RESTORE DATABASE db_name WITH RECOVERY;|
The query will rollback any uncommitted transactions and bring the database out of recovery mode.
Tip 2 – Apply Microsoft Fixes
If you’ve too many VLFs inside the transaction log, resulting in slow database recovery, applying Microsoft fixes may help.
Tip 3 – Run DBCC CHECKDB to Determine Database Corruption
Run DBCC CHECKDB on the problematic database. If it reports consistency errors, you must repair the database using the minimum level of repair option. For more information, read this: Read More

- Click OK again.
- In the Restore Database screen, enter name of the database you want to restore and click OK.
- The database will be restored.
