You might need to look at full open-file server based backup options like Acronis (I've used Pallindrome and a few others over the years but not with much success. They seem to work fine with SQL Server and Oracle but not VFP databases consistently). I did find this:

http://www.handybackup.net/foxpro-backup.shtml

which claims to backup open foxpro databases but I've never used it.
