Bert,
The size of the entire AC file that I double backup daily is 208 MB, but this is the entire AC. I think that the actual database is 36.5 MB.
The backup on either the external drive or the thumbdrive just takes 30 to 60 seconds.
I have downloaded the backups to various computers with good results.
Your thoughts?
Jim
