DRS Softech Microsoft 365 Backup Tool vs GMvault

DRS Softech Microsoft 365 Backup Tool backs up Office 365 mailboxes, public and archive folders, email, contacts, calendars, tasks, and OneDrive files. It can export mailbox data to more than 15 formats, including PST, EML, MBOX, PDF, CSV, JPG, PNG, DOC, MSG, and HTML. Migration destinations include Google Workspace, Office 365, IMAP, iCloud, Zoho Mail, Yahoo, Yandex Mail, Thunderbird, and other email clients. It restores OST and PST files to Office 365 administrator or user accounts and supports restoring selected individual items. Administrators can use Impersonation Rights to access multiple mailboxes for backup or restore without separate login details. Other controls include date-range filtering, custom folder names, separate attachment saving, PST splitting, and duplicate-email removal. Backups can go to a computer, local or external drive, SAN, NAS, or supported cloud storage. The free demo backs up 50 Office 365 mailbox items per folder. Linux, macOS, and Windows are listed platforms. Organization-wide or multi-user permissions may require Microsoft 365 administrator consent, and user sign-in must be enabled.

GMvault backs up Gmail accounts to help preserve email correspondence and can restore a local email repository to Gmail. It offers full synchronization as well as incremental quick synchronization. The tool runs from the command line and is described as user-friendly. XOAuth is enabled by default as the recommended sign-in method; its token is stored in $HOME/.gmvault after first authentication. Users can alternatively sign in with a Gmail password, which is encrypted if they choose to save it. Emails are stored by default in $HOME/gmvault-db, or %HOME%/gmvault-db on Windows. Restore operations include --resume and --restart options for avoiding re-upload of emails already processed. GMvault is free and open source under GNU-AGPL-3.0, with Linux, macOS, and Windows support. The project documents binary installs for those systems and installation from source through Python setup.py, pip, or easy_install. PyPI lists version 1.9.1, published March 31, 2016.
