14 — Backup & restore
What this screen is for
Keep a safe copy of your data (products, sales, customers) so you never lose it, and put it back if a PC fails.
Before you start
- You are logged in as a manager/administrator.
- Have a USB drive or a network/cloud folder ready for the backup copy.
Where your data lives
OmniPrime POS stores everything in a single database file on the till
(OmniPrime.db in the app's data folder). Backing up = keeping safe copies of that file
(and your product images).
Step-by-step
1. Close the app
Make sure no sale is in progress, then close OmniPrime POS so the file isn't in use.
2. Copy the database file
Copy OmniPrime.db to your backup location (USB / network / cloud). Name it with the date,
e.g. OmniPrime-2026-05-30.db.
3. (Recommended) Schedule it
Make this part of the daily close — one copy per day kept for at least a week.
4. Restore
On a fresh PC, install OmniPrime POS, close it, then copy your backed-up OmniPrime.db into
the app's data folder (replacing the empty one). Open the app — your data is back.
Real example
- Close the app at end of day.
- Copy
OmniPrime.dbto a USB stick namedOmniPrime-2026-05-30.db. - To restore on a new PC: install, close, drop the file in the data folder, open.
If something goes wrong
| You see this | What it means | How to fix it |
|---|---|---|
| Can't copy — file in use | The app is still open. | Close OmniPrime POS first. |
| Restored data is old | You restored an older backup. | Use the most recent dated backup. |
| App won't open after restore | Wrong/locked file copied. | Restore a known-good backup; keep several dated copies. |
FAQ
Q: How often should I back up? A: Daily at close, and keep at least a week of dated copies.
Q: Where is the data folder?
A: Under the app's local data location (%LocalAppData%\OmniPrime). Your installer/admin can confirm the exact path.
Q: Does it back up automatically to the cloud? A: Not by itself — copy the file to a cloud-synced folder (OneDrive/Google Drive) to get off-site copies.
