BackupMGR is a self-hosted server backup platform for system administrators, managed service providers, and hosting teams. A Go agent polls outbound to a web control panel, while agentless connections support hosts reached over SFTP, rsync, or FTP. Backup jobs can protect files, MySQL and PostgreSQL databases, combined file-and-database sets, or full disk images. The platform creates encrypted, deduplicated snapshots in S3-compatible storage and keeps repositories isolated by host. Administrators can schedule incremental backups, apply daily, weekly, and monthly retention, review point-in-time snapshots, restore selected files to another folder, and monitor job status through logs, alerts, and health checks. A REST API supports host and job management, backup runs, and snapshot browsing. Customers install the control panel on their own Linux server and choose their storage destination.
