## This is an example maildir configuration file.
|
|
##
|
|
## The maildir handler slowly creates a backup of each user's
|
|
## maildir to a remote server. 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. It is up to you to
|
|
## periodically remove this directory or old maildirs in it.
|
|
## The defaults are useful in most cases, just make sure
|
|
## to configure the source and destination information

## each users maildir will contain these files:

## daily.1, daily.2, daily.3, daily.4, daily.5, weekly.1, weekly.2,
