Our Citrix Xendesktop DB is mirrored between servers at 2 sites. As such the recovery model is set to Full. Even though we successfully run full backups on that DB each night, the logs for the database don't get purged and are 30GB for a DB that is about 100mb or less. FWIW we're using Netbackup.
How can i purge these logs without reducing our ability to fully restore if need be?
