GWS Backup vs Redstor Google Workspace Backup

GWS Backup is self-hosted software for backing up Google Workspace Gmail, Drive, Shared Drives, Calendars and Contacts. It can send backups to Google Drive, local disks or NAS, Amazon S3, and Azure Blob storage. After its initial full backup, it transfers only new mail and changed files. Restores can cover a workspace, account, folder, email or file, including transfer to a different user or download. Deleted source items remain in backup for one year; operators can configure version history and vault pruning. A live monitor shows transfers, and an audit trail records actions and backup results. Security options include 2FA and separate administration and restore roles. The maker says backups stay in storage controlled by the customer and do not pass through its infrastructure. Deployment options include Windows, Linux, cPanel and Docker. GWS Backup requires Node.js 22.5 or newer and an activated licence key. Its plan is free, covering up to 10 client workspaces and unlimited accounts, with one running installation per licence key.
