Mail Backup X vs Spanning Backup

Mail Backup X is a mail backup, archive, management, and conversion product for home users and businesses. It backs up Apple Mail, Outlook, Office 365, Thunderbird, Postbox, and online services that support IMAP or Microsoft Exchange. Backups run continuously, and archives can be restored or exported and converted into EML, PST, RGE, MBOX, and OLM formats. Search filters include sender, subject, words, date range, attachment type, and AND/OR queries. Backups can be mirrored to Google Drive, Microsoft OneDrive, Dropbox, FTP, or USB storage. The vendor says archives are encrypted and stored on destinations controlled by the user rather than its servers. If a user loses the personal encryption key, even the vendor cannot decrypt the data. Team Edition adds remote backup management, an admin dashboard, and alerts about team backup status. Personal Edition costs $59, paid once for one user, up to five mail profiles, installation on two computers, and one year of maintenance updates. A fully functional 15-day trial and 24 x 7 email technical support are offered. It supports macOS 10.13 and above and Windows 8 and above, with native NAS apps for Synology and QNAP.
