better way to backup 50 Gig db?

[Mitchell Maltenfort]

I'm using MySQL to manage data on my computer .

The total data is 50 Gig in MyISAM folders.

As I type, I already have the folder with the myd, frm, etc being
copied offsite.  As I understand it, if this computer dies tomorrow, I
can reinstall MySQL on a new computer, drag over the archive, stick
the folder under "data" and I'm back in business.

Or am I dreaming?

I'd rather be corrected now than find out the hard way.

Any advice?+
