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.

Zerto

Zerto helps you protect your data and applications across on-premises, hybrid, and multi-cloud environments. Instead of relying on traditional periodic backups that can result in hours of data loss, you can use its continuous data protection to achieve recovery point objectives of seconds. You can easily move workloads between different platforms, such as migrating from VMware to Azure or AWS, without complex reconfiguration.

The platform simplifies your operations by managing disaster recovery and backup through a single interface. You can perform non-disruptive testing to ensure your recovery plans actually work before a real disaster strikes. It scales to meet the needs of large enterprises, protecting thousands of virtual machines while maintaining high availability for your most critical business services.
