##
## 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.
##
## Note: This handler assumes that the remote shell is set to bash
##
## The defaults are useful in most cases, just make sure
## to configure the source and destination information
when = everyday at 21:00
## each users maildir will contain these files:
## daily.1, daily.2, daily.3, daily.4, daily.5, weekly.1, weekly.2,
## weekly.3, monthly.1
## if keepdaily is 5, keepweekly is 3, and keepmonthly is 1
keepdaily = 5
keepweekly = 3
keepmonthly = 1
# directory which contains all the maildirs
# this directory is expected to have subdirectories lettered a-z and
# in each letter subdirectory are the users Maildirs which start with
# those letters
srcdir = /maildir/riseup.net
# put the backups under this directory
destdir = /crypta/maildir/riseup.net
desthost = kakapo-pn
# For the backup rotation to work, destuser must be able to run
# arbitrary bash commands on the desthost.
destuser = backer
# remove any maildirs from backup which might have been deleted
remove = yes
# use a ssh-mux to reuse connections, see the following article
# http://www.debian-administration.org/articles/290 for an example
