It may be a perfectly legitimate Windows backup tool, but the description you posted (“advanced, efficient and comprehensive”) is largely marketing language and isn’t something I can verify safely without independent documentation and hands-on testing.

If you’re considering Z-DBackup (or recommending it to others), these are the security and reliability points that matter most for a backup product:

What to verify before trusting any backup tool
  • Restore reliability: The #1 risk is discovering at disaster time that restores don’t work. Do regular test restores (files and full-system images if you use them).
  • Versioning / retention: Ensure it can keep multiple historical versions (important against ransomware and accidental changes).
  • Encryption: If backups can contain sensitive data, confirm it supports strong encryption and that you control the password/key (and have a recovery plan).
  • Ransomware resilience: Backups should not be continuously writable from the same Windows session. Prefer offline, rotated external drives or a destination with immutable/versioned backups.
  • Uses Windows VSS correctly: For “open files” and consistency (Outlook PSTs, databases, etc.), support for Volume Shadow Copy Service matters.
  • Signing and download hygiene: Download only from the vendor site, verify digital signature (if provided), and scan the installer with your AV and optionally VirusTotal before installing.
  • Backup format: Check whether the backup output is a standard format or a proprietary container. Proprietary formats can be fine, but they increase lock-in risk if the product is discontinued.
  • Privilege and service behavior: Backup tools often run with high privileges. Prefer least-privilege configuration and be cautious with any “remote management” or exposed network services.

Practical recommendation
Even if Z-DBackup works well, treat it as “untrusted until proven” like any backup tool: run a pilot, do repeated restore tests, and implement a 3-2-1 strategy (3 copies, 2 different media, 1 offsite/offline). That’s what determines whether it’s actually “comprehensive” in real-world failure scenarios.
