The Google repository looks good - however, it would be a cold day in hell if I ever put my financial records in an on-line storage area unless they were seriously encrypted. Too many hackers out there.
I use MS Money for keeping my local records, and what I do is put the Money data file on an encrypted thumb drive and carry it with me. That way I can access my records on my desktop or my laptop when on the road, and they are not present in my computers. Oh, yeah . . . I have triple redundancy backup in Thumb drives.
But, an encypted data file stored at the Google site would be useful.
