seems very helpful ( http://www.openfusion.net/net/fun_with_brackup)
But i have a  few  queries  with the config file :
[TARGET:backups]
type = Filesystem
path = /backup

[SOURCE:imapsource]
path = /var/spool/imap
chunk_size = 5m           # what does this mean ????
gpg_recipient = 5E1B3EC5     # what does this mean ????

[SOURCE:bradhome]
chunk_size = 64MB
path = /raid/bradfitz/
ignore = ^\.thumbnails/
ignore = ^\.kde/share/thumbnails/
ignore = ^\.ee/minis/
ignore = ^build/
ignore = ^(gqview|nautilus)/thumbnails/


and suppose i want to backup it up to another server with scp / ssh     how
is this attatined .
secondly in whant format is the backup maintained .
