!Okay, so "find -?time 3 -print" should find all files ?'d within the
!last three days, right? Nope. To wit:

[ listing omitted ... explanation below ]

!==================================================
!As you can see, -mtime 1 included only those files modified in the day
!preceeding, and -mtime 2 included only those files modified in the day
!preceeding the day preceeding, _not_ files modified within the last two
!days. This obviously makes it difficult to use
!
!% find . -mtime (epoch_days) | afio ...
!
!to back up the filesystem incrementally.

For that you use:

% find . -mtime +(epoch_days) | afio ...

(the + means that it will look at anything older than epoch_days; a -
 would indicate that it would be looking at things younger than epoch_days).
