I attempted to search for this issue, but kept getting timeout error messages, so I don't know this issue has already been discussed.

When I tried to restore a backup of the database I created, I received the following error:
DBISAM Engine Error #8965 Index page buffers corrupt in the table 'Thumbnails'

I ran the database repair utility and I hope that this fixes the problem. It's interesting that a newly created backup failed. I created the database on my laptop. Backed it up and transferred it to my desktop. I was able to do an inital restore to get the data in and then the backup no longer works after that.
