Comet Backup

Comet Backup gives you total control over your data protection strategy with a fast, secure, and highly customizable backup solution. You can protect everything from individual files and folders to entire disk images, Microsoft 365 environments, and databases like SQL or MongoDB. The software uses client-side deduplication, meaning your data is compressed and encrypted before it even leaves your device, saving you significant bandwidth and storage costs.

Designed specifically for IT professionals and service providers, the platform allows you to choose your own storage destination, whether it's local hardware or cloud providers like AWS, Azure, or Wasabi. You can manage all your backup jobs through a centralized web interface, white-label the software with your own branding, and scale your operations without worrying about per-device licensing fees.
