Your Synology Backups Are Held Hostage. Here’s the Escape Plan.
Synology’s Hyper Backup creates .hbk files in a proprietary, undocumented format β meaning your backups are locked inside a system you don’t control. hbkit is a community-built tool that reverse-engineers the format, offering a critical escape hatch when Synology hardware or software fails. If your backup strategy relies on a closed format, you don’t have a backup. You have a hostage.
