This article will outline how to repair a UniFi Video database for both Linux and Windows platforms.
NOTES & REQUIREMENTS:
UniFi Video will attempt an automatic database repair if it suspects any database corruption, caused by an incorrect shutdown for example. A user should only need to do this manually if that startup repair did not work, or if database corruption is definitely present but the auto repair didn't trigger.
