Since emails in a Maildir system are separate files, the backup task
will miss any emails delivered after tar begins.
The first thing that my backup job does is to touch(1) a lock file.
The last thing it does is remove the lock file.
I don't directly run fetchmail from a cron job, but wrap it in a
script. The first thing it does is check to see whether the lock
file exists, and nicely exits if it does. Otherwise, it runs fetchmail.

This is the beauty of Maildir. You never have to worry about locks.
