sql backup detected corruption in database log

Unfortunately I am not a SQL Admin.  I have moderate SQL experience at best.

I have  four or five database in SQL 2005 that were the primary members of a mirror. The physical server (the one I am currently working on) was virtualized (P2V) then started as a virtual machine. Downtime was minimal. Maybe an hour or so I believe.

Although I didn't check immediately after boot up, I have since noticed the mirror status is suspended.  Attempts to resume fail.  It appears my best bet is to backup the database, restore on the target, then recreate the mirror.  The problem is, attempts to run a Full backup of the database returns the following error on all the database I've tried to backup.  After about 20% is says: SystemData.SqlClient.SqlError: BACKUP detected corruption in the database log.  Check the errorlog for more information. (Microsoft.SqlServer.Smo)

I've tried setting the recovery type to Simple, but that fails telling me the database is part of a mirror and to be honest I'm not sure setting to Simple is the best option. 

As it stands, the mirror is broken and I can not perform a full backup. 

Any suggestions on how to proceed are greatly appreciated.

Thank you.
