It sounds like you're experiencing issues with your KC3000 SSD while trying to back up using Paragon. Here are a few steps you can try to resolve the issue:
Check for Firmware Updates, Verify Disk Health, Update Paragon Software, Run Disk Check
Try Alternative Backup Methods: Instead of selecting the entire disk, try backing up individual partitions one at a time. This can help identify if a specific partition is causing the problem. Disable Antivirus/Firewall, Check Event Viewer Logs, Reinstall Paragon Software

What, specifically, is error 0x1116f?

That kind of failure during backup is usually not caused by Paragon itself, but by either a disk read issue, partition inconsistency, or Windows-level access problem.

First, check the health of your KC3000 SSD. Use SMART tools (like Kingston SSD Manager or CrystalDiskInfo) to confirm the drive isn’t reporting errors. Even a small number of bad sectors can cause backup jobs to fail partway through.

Next, run a file system check on all partitions:

• Open Command Prompt as admin
• Run: chkdsk C: /f /r (repeat for other partitions if needed)
  This will fix logical errors and scan for bad sectors.

Also check Windows Event Viewer (Windows Logs → System) around the time of failure. Look for disk, NTFS, or controller errors — they often reveal the exact cause.

Since you’re backing up the entire disk (including system partitions), try switching the backup mode:

• Use sector-by-sector backup (if available), or
• Try backing up partitions individually instead of the whole disk

Other things to try:

• Disable antivirus temporarily (it can interrupt disk access)
• Make sure VSS (Volume Shadow Copy Service) is running properly
• Update SSD firmware and storage drivers
• Check cable/connection if it’s not a laptop (less likely for NVMe, but still worth noting)

If it consistently fails at the same point, that strongly suggests a bad sector or unreadable block on the SSD.

In short, verify disk health and file system integrity first — most “backup fails after a few minutes” issues come down to read errors on the source drive rather than the backup software itself.

That error can be frustrating, especially when it occurs while backing up the OS drive. I’d start by checking the backup destination for available space and making sure the drive is healthy and properly connected. It may also be worth checking the backup software’s logs for the exact point where the process fails. If you can share the backup software, Windows version, and the full error details, it should be easier to narrow down the cause.
