Why SquirrelBak?

📁 Real-Time Sync

Monitors your folders and instantly backs up new or changed files—no manual triggers needed.

🔁 Auto Resume After Downtime

If the server or network goes down, SquirrelBak picks up right where it left off—no data loss.

🖥️ Repurpose Idle PCs

Turn an old or unused computer into a silent, secure remote backup machine—zero cost, full control.

⚡ Backup-Only. Remote-Site Only.

No restore. No sync. No cloud. Just one-way, folder-level backup from your server to a PC in another physical location. Designed for continuously growing data — simple, focused, and deeply safe.

🛡️ Full User Control

You decide which folders to back up—and which to exclude. No automatic decisions. No surprises.

🔒 Security Through Isolation

The backup PC only receives data—it never exposes your files to the network. One-way sync means one less attack surface.

How It Works

1

Deploy

Run the Sender on your production server, and the Receiver on an idle PC in a separate location (e.g., office, home, closet).

2

Configure

Select source folders with growing data (e.g., OA, logs, documents). Set IP, port, and destination. No login. No restore.

3

Forget It

SquirrelBak runs silently—copying only new files, forever. No interaction. No risk. Just safe, continuous backup.

User Stories & Tips

Real insights from users who trust SquirrelBak for their data safety. From home offices to small businesses, see how others are backing up like squirrels.

"We run a SaaS system on Alibaba Cloud for car dealerships. Now I use SquirrelBak as the final line of defense: nightly SQL backups → RAR → auto-delete old → sync to an offline PC. It just works. Is it perfect? Yes."

"I run SquirrelBak from my home server to an old laptop in the basement. It’s been silently copying security logs for 8 months—zero issues. When my main drive failed last month, I didn’t panic. The data was safe."

"We use it for our clinic’s patient records folder. No cloud compliance headaches. Just real-time backup to a locked PC at a staff member’s house. Simple, secure, and HIPAA-friendly."
