Or you could just use doveadm -o plugin/zlib_save= to override the setting.
Re: [Dovecot] dsync backup; compressed to uncompressed
Ok, I think I found an answer. I don't know if it's the right one... I duplicated my dovecot.conf to backup.conf. I then removed this part from plugin {} zlib_save = gz zlib_save_level = 9 I then add "-c backup.conf" to my dsync command. This appears to allow dsync to read the compressed mdbox accounts, but when it writes the backup in maildir format, everything is uncompressed. -Original Message- From: dovecot-boun...@dovecot.org [mailto:dovecot-boun...@dovecot.org] On Behalf Of Michael Smith (DF) Sent: Wednesday, January 29, 2014 12:04 PM To: 'dovecot@dovecot.org' Subject: [Dovecot] dsync backup; compressed to uncompressed I need to backup some of the mailboxes on our system.
