Repairing a database is often trickier than a restore or a recovery; the database may be functioning normally except for an isolated problem that prevents normal transaction processing. Database repair activities may or may not require a database recovery or restore. Often a single object or schema is damaged, or the underlying infrastructure is corrupt and must be replaced or repaired.
Blue Gecko can perform various granular database repair operations depending on the nature of the problem, the version of the software, type of hardware, etc. Our DBAs have provided creative solutions for many customers; we have repaired data that was previously thought lost or permanently damaged. Though no one can guarantee a successful database repair, Blue Gecko DBAs have broad and deep experience with complex corruption and failure scenarios.
