You do not need to purchase a licence for every team member. A single licence is sufficient to back up your team’s data.
However, for security and privacy reasons, we can only back up data from users who have authorised ProBackup. Private projects or boards belonging to other team members will not be included in the backup unless authorised.
To ensure all data is backed up, you can either:
Invite other team members via https://app.probackup.io/settings/users
Ask your team members to add the admin account to each project or board
Tip: Consider creating a dedicated account for managing backups (e.g. [email protected]) and ask your team to always invite this user to their projects and boards.
