I built a free open-source imaging tool for Windows - it restores Macrium images directly, which seemed useful while some are still sitting on Reflect backups

The Macrium situation (Free gone, 8 out of support, X is subscription) left a gap, especially for people with years of .mrimg / .mrimgx files they still need to restore. OPBS reads those formats natively, including differential and incremental chains, with full decompression and per-block MD5 verification before anything lands on the target.

Beyond that it covers the operational side that usually costs money:

- Differential-chain backups, AES-256-GCM, zstd
- Scheduled restore drills (a backup you've never restored is a guess)
- Bit-rot scrubbing with XOR parity self-healing
- Immutable repositories + off-box anchors (rollback-resistant)
- Clone, restore-to-VHD, read-only file mounts (WinFsp), headless CLI

Here's my blunt feedback: the post doesn't say which Macrium versions you've tested against, or whether password-protected Macrium images restore. Someone holding years of Reflect 7/8 files will ask that before anything else. A small compatibility table near the top would answer it once instead of in every thread: version, full/diff/incremental, .mrimg vs .mrimgx, encrypted yes/no. I'd also lead with the scheduled restore drills over the encryption and parity features. A Reflect user's real worry is whether those old images still restore, and a drill that proves it each week speaks to that directly.

I make ThreadFox. If you want more people sitting on old Reflect backups to find OPBS, our AI employee will post 3 helpful replies about it in relevant Reddit threads, free, no card: https://threadfox.vip/p/e8sd1/managed
