DRS Softech Microsoft 365 Backup Tool vs Synology Active Backup for SaaS

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.

Synology Active Backup for SaaS backs up Microsoft 365 and Google Workspace data to Synology NAS servers for recovery after data loss or service downtime. Microsoft 365 coverage includes OneDrive for Business, SharePoint Online, Exchange Online, and Teams. Google Workspace coverage includes Drive, Gmail, Contacts, and Calendar, including shared drives, labels, and attachments. Microsoft 365 backups can run continuously, manually, or on a schedule; continuous intervals adjust from one to ten minutes based on detected API request rates. Both services support file versioning, and Google Workspace versions can be retained for a chosen period or kept in full. The Microsoft 365 Recovery Portal lets administrators and employees restore or export backed-up data, with self-service access dependent on configuration. The product is a free add-on for a compatible Synology NAS, with unlimited accounts subject to NAS storage capacity. Active Backup for Microsoft 365 requires DSM 6.1-15217 or later. Deduplication requires an x64 NAS using Btrfs, and neither service supports secondary backups. Google Workspace setup requires configuring the Drive SDK API and creating a service key.
