Settings for Backing Up Maildirs

	So, I'm backing up a bunch of maildirs. These are huge
directories full of files that never change, though new files are
added. There are a few files that change (the IMAP server's index
files), but they're not quite as big as everything else.

	These are the settings I'm using now, do these make sense for
backing up a lot of files that never change?

merge_files_under = 8kB
max_composite_chunk_size = 64MB
chunk_size = 256MB
