After requesting a backup, one or several zip files will be sent to you via email. The email address where the backup is sent can be selected during the Email Backup setup/download flow. This process could take 24-48 hours depending on the size of your inbox. If there's a lot of messages, you will receive multiple zip files. Please note: Email Backup download links are only available/valid for one (1) hour from the time they are sent.
If you haven't received this within 48 hours, please check your spam/junk folder(s.)
