I have been following backup solutions for many years and this seems to do what I need. I currently use Cobian on W10. I am considering changing my Windows email from LiveMail (which has not been supported for a long time but can still be downloaded if you search hard enough) to Thunderbird but, unlike Livemail, which backs up each email message into a separate file, Thunderbird seems to place all of its emails into a single mailstore file.
As I schedule a backup daily to NAS storage backing up a single mailstore file daily will take up a lot of space I currently take a full backup every 28 days and keep three full backups and the incremental changes between.
Now for my question - Does Duplicati cope with this situation well? Are there any Thunderbird users who are using Duplicati?
I am also concerned about the fact that Duplicati is still in beta although it has been in development for several years. If there had been a stable version I would probably have changed to it long time ago.
I am in the process of changing computers so it would be an ideal time to change my backup strategy.
