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.
