This sort of manual backup is probably the most reliable...but only as reliable as one's own habits --in this case, actually doing the backup. When you consider the monthly cost of automatic off-site backup like Carbonite, why look any further?

A suggestion; A long time ago I developed a method to overcome defects in early hardware/software that would squash a document. I'd save the document on several different media, and with many versions changes as I would work on. The days of the floppy disk are gone, but now one could save a doc on the hard drive and another copy or two on removable media, say a USB stick, SD card, or CD. And if at every session, or day, or so forth the doc version were renamed to "doc-a," then to "doc-b," etc, only the latest version would be lost to an attack. I found this worked well back in the late 80s and 90s with both large docs and large printed circuit board layouts. For the latter, at that time it wasn't uncommon for the program to say "no good" and place a large, diagonal, yellow error line thru a week's worth of work. Essentially telling me the work was all for naught. No recovery was possible. With multiple savings & multiple media, I found only the last day or half day's effort was gone. Since I've just begun another lengthy text, think I'll go back to some ancient habits. Jim Ussailis
