For email email am having the email duplication issue when am doing the backup.
Am having multiple copies of a mail file on the backup server.
Does it mean that if I use "--fuzzy --delete-after" only the most recent
mailfile will be on the backup server ??
e.g On LIVE server : my-file:2,S
On BACKUP server : my-file:2,S + my-file:2, + my-file:2,SF
"my-file:2,S" is the current file.
So on the backup only "my-file:2,S" must exist.
Will it solve the prob ??
