Kernel Google Workspace Backup and Restore vs Synology Active Backup for SaaS

Kernel Google Workspace Backup and Restore is Windows software for backing up and restoring data from Google Workspace. It covers Gmail, contacts, calendars, Drive, Shared Drive, Groups, Chat, Docs, and Sheets. Mailbox lists can be supplied in a CSV file, and backup jobs can span multiple domains. An incremental option skips items already migrated and captures newly added data. Google Chat backups include direct and group chats, spaces, and history; attachments are saved separately, and chat content can be exported to PDF or HTML. Google Docs and Sheets can be exported to local or network storage while preserving their content and formatting. Workspace exports include PST, MSG, EML, PDF, DOC, DOCX, MHT, and HTML. Restore choices include selected data, folders, mailboxes, Workspace accounts, and Google Groups. It can restore PST and OST data to Workspace, and the vendor says Outlook is not needed for PST restoration. The trial is limited to 10 items per folder and five Drive documents per account. Prices include $49, paid once for a single-mailbox backup license and $99 as a one-time purchase for a single-mailbox backup-and-restore license.

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.
