Frequently asked questions
Can you recover the data if I have no usable backup?
Often, yes. When no recent backups are available we use advanced techniques to extract and restore as much data as possible. We have recovered databases where the only backup was out of date, and where the backups themselves were corrupt. The sooner we start, the greater the likelihood of recovering all of your data.
Will I lose data during the repair?
Our focus is on little to no data loss. Where possible we restore individual pages from backups and rebuild damaged indexes rather than discarding anything. The one thing to avoid is REPAIR_ALLOW_DATA_LOSS, which sacrifices data to make the database structurally consistent.
How long does a corruption repair take?
Generally your database will be up and running within 24 to 48 hours. We treat corruption as an emergency and drop everything until it is back up. Delaying the repair can eliminate recovery options if the damage gets worse, so the quicker we start the better.
Do you need remote access to my server, and how is it secured?
We will discuss access on the free 30-minute consult and agree on an approach that fits your security requirements.
Which SQL Server versions do you support?
All of them. We repair any SQL Server version and edition, including Express, Standard and Enterprise. That covers SQL Server 2005 and newer, and in some cases we even service SQL Server 2000.
What does the repair cost?
The 30-minute consult is free. Once we understand your situation we set clear expectations and pricing before the repair starts.
Should I run DBCC CHECKDB with REPAIR_ALLOW_DATA_LOSS?
No, not before talking to us. It is the most aggressive repair option: it removes corrupted pages or objects to restore structural integrity, so data loss is not only possible but likely. Some repair suggestions found on the internet can cost you data. Back up the database as it is, save the CHECKDB output, and read DBCC CHECKDB with REPAIR_ALLOW_DATA_LOSS for the details.
Can I keep using the database while it is corrupt?
Corruption does not get better on its own, and ignoring it will not help. Do not restart the instance: a restart can leave the database stuck in Recovery Pending or marked Suspect, which stops anyone using it. Take a backup of the database as it is and call us, because delaying the repair can eliminate recovery options.
Watch: what to do when CHECKDB finds corruption
Steve Stedman and Derrick Bovenkamp talk through what causes SQL Server corruption, usually I/O problems such as iSCSI firmware or antivirus misconfiguration, the symptoms to watch for, why daily CHECKDB and tested backups matter, and when to call for help (57 minutes).
