Mail Backup Library

Cloud Backup Components

Cloud Backup offers a convenient and dependable method for backing up Gmail and Office365 emails. Emails are archived in the widely recognized .eml format, compatible with popular email clients like Outlook, Thunderbird, Apple Mail, and others. Messages and associated information are saved to disk by default, with the option to intercept events if a different storage location (e.g., database, S3) is preferred. The flexible components allow selectively skipping messages, managing the maximum number of concurrent connections, filtering messages, and more.
