[MM3-users] Re: [GSoC 2026] [Feature Proposal] Per-List Backup and Restore Support

Thank you Stephen, this is very helpful.

I understand that the implementation discussion is better continued on mailman-developers, and that mailman-users is more appropriate for feedback about user experience and feature demand.

Your guidance on scope and architecture is especially useful. My current understanding is:

• the backup/restore logic should live in Mailman Core
• the initial interface should be exposed through the mailman utility
• Postorius, if added, would come later as an additional UI
• the backup format should be versioned and include metadata such as timestamp and schema compatibility
• archives and site-wide web template customizations are out of scope for the first version
• subscription preferences and restore permissions need special care

I will refine the proposal in that direction and continue the implementation discussion on mailman-developers.

Thank you again.
