It wastes disk seeks since it now has to read mail from 2 (or more) places in filesystem, so probably not a good idea. So in any case SiS most likely increases your disk IOPS usage. > 4º Can I "undo" SiS if I have problems? dsync will help the other way around too. > 5º We use bacula to save indexes & mdboxes, and we recover mailboxes using > doveadm import when a user "makes a fatal mistake" wiping all her Inbox.

Even if you knew what SIS files were used, there's no simple way to restore those with proper refcounts. I think what really should be done is writing a tool that can create/restore backups, possibly de-SISing the attachments..
[Dovecot] Questions about single intance storage
Hello We are using dovecot 2.0.16 with mdbox+zlib. We are now testing SiS (Single Instance Storage) and I have 5 questions: 1º Is possible to "dedup" existing mdboxes? 2º Are attachments compressed with zlib if mdboxes already use zlib? 3º I have plenty CPU to spare, should I use a low value of mail_attachment_min_size , like 16KB ? 4º Can I "undo" SiS if I have problems? 5º We use bacula to save indexes & mdboxes, and we recover mailboxes using doveadm import when a user "makes a fatal mistake" wiping all her Inbox. If we enable SiS I am not really sure how can we safely restore a user's INBOX if that user has SiS attachments. Thank you for your (great) support. Maria
Re: [Dovecot] MS Exchange IMAP Proxy
It's working! I'll post a writeup on the wiki on monday. The last problem was it seems to need a writable home directory for mail_home even though all the mail is pass-through.This was included in Timo's original config, although I had accidentally removed it. In any case many thanks to Timo and everybody else who helped! Terry
