Hi - Been looking into this a bit more. It's maybe a bit tricky. The
files are technically 'created' each day. They "mysqlhotcopy" program
copies every single table file to a temporary area, which I back up.
However, the copy retains the date stamp of the original table, most
of which rarely change so these dates are often at least several weeks
in the past.

So, is there more to a date stamp than meets the eye? That is,
technically, the file:

\backup\toarchive\mysql\databasename\table.MYI

gets created daily in my hdup prerun script, then deleted in the
postrun script. But it should be identical in every respect, and the
date stamp certainly looks identical to the untrained eye. Is there
some other bit of information that's causing HDUP to realize it hasn't
just been sitting there for a day or week? If so, how else could I
avoid having these files re-backed up every day. It's making my daily
files about 70 megabytes bigger than needed.
