JPEG is generally fine for archiving, and it saves a tremendous amount
of space.  You don't normally resave archived JPEGs over and over, so
the lossy compression is not a factor (provided that you save the
original archive image with minimal compression).

Alternatives are lossless formats like TIFF or PNG, but they are only
practical if you have a great deal of space for archives.  I can only
put one TIFF on a CD, for example, and with thousands of images at one
image per CD, it gets impractical.  I would if I could, though.

PSDs are sometimes even larger than TIFFs.
