Thanks for the tips guys. I've thought about other possibilities, however, our project teams have been at times as big as 8 architects all sharing and referencing the same files. It is a necessity to work from the server today. As for the backup, it is only run during non-work hours when files have been closed. Even then, the backup server does not have rights to restore or update back to the working directories on it's own. This new issue has only come up recently with the update to 12.5, never in the past have I had network file corruption issues like this.
