I'm currently doing nightly full backups of /home. I'm not sure if a
full back up is the best way to do backups. I know with my

how do you guys backup Maildir? whats the best way of doing it? ...How do you backup e-mails for users when during the backup, they are deleting the e-mails from the Maildir (POPping) and at the same, and the SMTP server is also writing to it. ...
One way was along the lines of our discussion some time ago on Exim list, to deliver to either a global or per-user backup pool of messages which are only deleted after the backup system has seen them (or possibly deleted by the backup itself).
Yes, I can do that perfectly - delivering to a per-user backup Maildir somewhere, but remember that in this case, we have the overhead of dual delivery and a separate storage ;)
At one client we use the global backup system, and store the headers in an sql database, together with the exim message id and the md5sum of the file.
Not very good for restoring mailboxes/maildirs though. Sorry for the digression!
So, what happens if the client was to ask you for a backup of mail that he received last June? ;)
