Frequently Asked Questions

Q: 3. Does it work over the internet?

No. SquirrelBak only works on your local network (same Wi-Fi or wired connection), keeping your data safe and private — no remote access needed.

Q: 4. Do you collect my files or file names?

No. We do not collect file names, contents, or folder paths. The software only sees how many files are being backed up and their file types (e.g., .jpg, .pdf, .docx). Nothing leaves your network.

Q: 5. Where are my files backed up?

You choose the destination folder on the receiving computer, e.g., D:\Backups\John or /Users/BackupPC/Sarah. SquirrelBak copies files directly to that location.

Q: 6. Can I back up multiple computers to one machine?

Yes! You can run multiple SquirrelBak Clients on different laptops/desktops sending to one SquirrelBak Server. Each client can have its own folder.

Q: 8. Does it run automatically?

Yes. Once set up, SquirrelBak runs in the background, checking for new or changed files every 5 minutes (configurable) and backs them up silently.

Q: 9. What operating systems does it support?

Currently supports Windows 10/11 and macOS 12+. Linux support is planned for a future update.

1. What is SquirrelBak?

What is SquirrelBak?

SquirrelBak is a lightweight, enterprise-ready data backup solution designed specifically for business departments—especially finance teams—that need to ensure compliance, continuity, and security of critical digital documents without relying on IT departments or public cloud services.

It operates as a "consumer-grade but enterprise-ready" tool, meaning it’s simple enough for non-technical users to set up and manage independently, yet robust enough to meet regulatory and audit requirements.

Key Features:

Automatic Real-Time Sync: Monitors designated folders (e.g., "Invoices", "Contracts", "Expense Reports") and automatically backs up files to another local machine.

No Manual Effort Required: Eliminates risky practices like manual copying, USB drives, or WeChat file transfers.

Local & Private: Data is backed up directly from one device to another over the local network—never uploaded to the cloud, ensuring full data sovereignty.

One-Way Pull Architecture: The backup node pulls data from the source (e.g., financial computer) without reverse access, reducing cyberattack risks.

Preserves Folder Structure: Maintains original directory hierarchy for fast retrieval and audit readiness.

Supports Offsite/Remote Backup: Uses an old or spare PC (e.g., at home or in another office) as a remote backup node—achieving geographic redundancy without new hardware or cloud costs.

Anomaly Alerting: Optional integration with DingTalk or WeCom to send real-time alerts for backup failures, disk space issues, or file errors.

Audit-Ready Logs: Keeps detailed backup logs that can be reviewed during internal or external audits.

Compliance & Use Case Focus:

SquirrelBak helps organizations comply with regulations such as:

Ideal For:

Finance teams needing secure, compliant backup of accounting evidence chains

Businesses avoiding public cloud due to data privacy policies

Organizations seeking low-cost, no-IT-dependency disaster recovery

In short:

SquirrelBak is not just a backup tool—it's a compliance safeguard and operational insurance policy for financial data, built for simplicity, security, and autonomy.

No. We do not collect file names, contents, or folder paths. The software only sees:

How many files are being backed up
What file types they are (like .jpg, .pdf, .docx)

Nothing leaves your network.

Answer 5

You choose the destination folder on the receiving computer. For example: D:\Backups\John or /Users/BackupPC/Sarah. SquirrelBak copies files directly to that location.

Answer 6

Yes! You can run multiple SquirrelBak Clients (on laptops/desktops) sending to one SquirrelBak Server. Each client can have its own folder.

Answer 7

Files are copied as-is (no encryption) because they stay on your trusted local network. If you need encryption, you can enable it at the system level (like BitLocker or FileVault) on the destination drive.

🔐 Tip: For extra security, use an encrypted external drive as your backup destination.

Answer 8

Yes. Once set up, SquirrelBak runs in the background. It checks for new or changed files every 5 minutes (configurable) and backs them up silently.

Answer 9

Currently: Windows 10/11 and macOS 12+. Linux support is planned for a future update.

Answer 10

No. SquirrelBak can handle large files (videos, databases, etc.) as long as the destination drive has space.

Answer 11

SquirrelBak will pause and retry when the connection is restored. It resumes from where it left off — no need to start over.

Answer 12

Not yet, but this feature is planned. Right now, it backs up all files in the selected folder.

Answer 13

Since SquirrelBak copies files directly to a folder, restoring is as simple as browsing that folder and copying files back. No special tools needed — just drag and drop.

Answer 14

Not currently. SquirrelBak is designed for computers. But you can back up files from a computer that were synced from your phone (like photos or documents).

Answer 15

SquirrelBak is made by DoubleBlue — a small team that believes software should be simple, private, and honest. No investors. No ads. Just tools that work.
