Why not doing an rsync of the folders ? Will it damage the index file ?

OK , so I can see that there is this doveadm backup.. I don't use any MailDir on each account.. but all the emails are stored into the folder /var/www/mail? ( user 1 , user2, etc... ) in that case, a very basic backup would be? : *doveadm backup /var/www/mail? /var/backup/folder*? ? ( I prefer to ask before trying, because If break something.. here, they will kill me? :-( ) On 2/11/22 17:55, Stephane Magnier wrote:> Why not doing an rsync of the folders ?

I've had some success with restic to create incremental backups of mail directories on external storage. Very space efficient, and restic will handle all the de-duplication, pruning etc. You could write a filter to exclude the dovecot index files, or just restore to a different directory before copying the mails you want back to their destination.
