My total back-up files are 557MB.

It took many hours to FTP the files down to my local computer via a fast cable connection.

Does 557MB seem very large?

My forum has 6,800 members and 50 forums.

I'd estimate mabye 1.5m posts.

Also, my members are very active PM'ers.

Just curious how large others' back-up files have been.
