▋

The problem

You have four tools. None of them talk to each other.

rsync for sync. rclone for cloud. restic for backup. Some shell script you wrote at 2am to deduplicate. You still don't know if your backup actually works. Neither does anyone else's tool.

Pain #1

"Is this drive safe to reformat?"

You've been asking this for 6 months. You'll copy everything again just in case — again.

Pain #2

"Does my backup actually work?"

Last backup: 2 hours ago. But has anyone tried to restore it? No. No tool does this automatically.

Pain #3

"My photos are trapped in Google."

10 years of memories. First-class import doesn't exist in any competitor. You're stuck.

What Replicator does

migrate in → deduplicate → replicate → verify

The only tool that covers all four steps. No competitor does.

🔍

Integrity verification — the only tool that proves it

Every competitor shows "last backup: 2h ago." Replicator randomly samples your backup, test-restores files, and confirms hashes match. You get a signed report. If it passes, it works.

$ replicator verify --sample 1000

Sampling 1,000 random files from B2...

✓ 1,000/1,000 hashes match. Backup healthy.

Google Photos escape hatch

First-class Google Takeout + iCloud import. Deduplicated, dated, organized — into storage you control. 0 of 8 competitors build this.

🗃️

Content-addressed dedup (BLAKE3)

Finds every duplicate across phone + old drives + cloud exports. Not by filename — by content. Safe to delete duplicates with confidence.

⚡

3-2-1 backup, automated

Declare your destinations (local NAS + B2 + R2). Replicator handles the rest — continuously, verifiably, without babysitting.

🤖

AI-native — MCP server included

Chat with your backup. "What's at risk on D:\?" "Show me all PSDs with no TIFF copy." Claude calls the API. Replicator answers.

📋

Human-readable manifest

Every operation produces a signed manifest. What was backed up, hash, location, format. Give it to your executor — they'll know exactly what you have and where.

🔧

Unix-native CLI + JSON output

Composable, scriptable, webhook-ready. Pipe to jq. Cron it. Wire it into your existing automation. Works with rsync, rclone, S3, B2, local — anything.

AI-native by design

Talk to your backup.
It answers.

Replicator ships with an MCP server. Any AI assistant (Claude, ChatGPT, custom agent) can call it. You don't open a dashboard — you ask a question.

→ "Is it safe to reformat my D:\\ drive?" → Yes. 90% covered by H:\\.
→ "Convert all PSDs to TIFF" → Queued 37,404 files. Starting.
→ "What's my most at-risk data?" → 12,441 files on I:\\ with 0 copies.

Back up my photos folder to Backblaze B2.

replicator.scan()

→ 847,234 files, 4.2TB

replicator.replicate()

→ 12,441 new files queued → B2

Done. 12,441 new files replicated to B2. Backup verified — 500 sample hashes match. You're covered.
