Most backup software copies files and reports success based on file count. It never checks whether the destination actually matches the source. When you discover the difference, it's already too late.
Backup software has existed for decades, but a fundamental problem has never been solved: most tools cannot prove that a backup is intact. They copy files, increment a counter, and call it done. No one checks whether what arrived at the destination is byte-for-byte identical to the source.
This creates a dangerous illusion. Organizations believe they're protected because backups completed without errors. But "completed without errors" and "every file is verifiably intact" are two very different claims.
The consequences surface at the worst possible moment — during recovery. A file is corrupted. An audit trail doesn't exist. There's no way to prove what was backed up, when it was backed up, or whether it was ever verified.
GlacierLock was designed by a forensic examiner who spent years watching recovery failures happen because no one verified backups until it was too late. The solution isn't more features — it's a fundamentally different approach to what "backup complete" means.
Every file is hashed with both SHA-256 and MD5 at backup time, then re-hashed and compared at verification. A single flipped bit produces a completely different hash. There's no way to fake a match and no way for silent corruption to hide.
Every operation is logged to a hash-chained, append-only audit database. Each entry includes the cryptographic hash of the previous entry, creating an unbreakable chain. If any record is altered, the chain breaks and the tampering is detectable.
Before any backup runs, GlacierLock scans for 7 ransomware indicators: mass extension changes, file count spikes, modification surges, size inflation, known ransomware extensions, entropy anomalies, and ransom note files. If the environment looks compromised, the backup pauses instead of copying encrypted files.
GlacierLock is a Windows desktop application built for IT professionals, forensic examiners, and anyone who needs documented proof that their data is intact. It ships as a single executable with everything built in.
SHA-256 + MD5 computed on every file at backup and again at verification. Not a spot check. Not a sample. Every file, every run.
Natural language queries against your backup data, anomaly detection, restore planning, and contextual explanations. Runs locally via built-in Phi-4 Mini with zero internet required, or connect your own cloud AI key. Every AI feature degrades gracefully to rule-based logic — the product works fully without any AI configured.
S.M.A.R.T. monitoring with failure prediction, serial fingerprinting, and a Drive Health Passport PDF. Know the condition of your storage before a failure, not after.
Continuous lightweight backup of actively modified files on a configurable timer. Your work-in-progress is always protected without waiting for a scheduled run.
Compliance mode generates chain-of-custody PDFs, integrity reports, and Drive Health Passports. Built for environments where proving backup state matters — audits, litigation holds, forensic case work, and insurance documentation.
Your backup data never leaves your machine. Local AI runs entirely on your hardware. Cloud audit sync (Pro tier) pushes hashed metadata only. If you connect cloud AI, you bring your own API key and can inspect exactly what's sent.
Forensic examination has a precise standard for data integrity. Every file is hashed. Every action is logged. Every transfer is verified. The record is append-only and tamper-evident. You never assume a copy is intact — you prove it.
That standard doesn't exist in backup software. Tools copy files, report a count, and move on. There's no cryptographic proof, no tamper-evident log, no mechanism to demonstrate that what landed on the destination matches what left the source.
GlacierLock was built to bring that standard to backup. Every design decision — dual-hash verification, hash-chained audit log, chain-of-custody documentation, honest disclosure of limitations — comes from a discipline where data integrity is not assumed. It is documented and proven.
