It is designed to be run with +## low overhead in terms of CPU and bandwidth, so it runs pretty +## slow. Hardlinking is used to save storage space. The actual +## maildir is stored within each snapshot directory. +## +## The basic algorithm is to rsync each maildir individually, +## and to use hard links for retaining historical data. +## +## We handle each maildir individually because it becomes very +## unweldy to hardlink and rsync many hundreds of thousands +## of files at once. It is much faster to take on smaller +## chunks at a time. +## +## Any maildir which is deleted from the source will be moved to +## "deleted" directory in the destination.
