[Dovecot] Questions about single intance storage

[Maria Arrea]

Hello Timo.

 If we can not safely restore from backup a user's mailbox with SiS enabled, we can not enable SiS. Any plan to include this backup recovery tool in dovecot 2.0.X or 2.1?

 Regards
 Maria

 > 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. Hm. Yes, that is problematic.. 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..
