How do I back up my program's data?

Updated October 12, 2026

The short answer

Take a copy of the program's data regularly and keep it somewhere other than the computer itself: an external drive, a second disk or cloud storage. A simple rule is one copy every working day and a weekly copy kept outside the shop. Most important, test a restore at least once, because a backup you have never restored cannot be trusted when you need it.

A backup routine that suits a small shop

  1. 1
    Name the person responsible

    One named person takes the backup, not whoever remembers.

  2. 2
    Copy at the end of the day

    Use the program's backup command to an external drive, after sales are closed.

  3. 3
    Name the file with its date

    So you know which copy to restore without opening them one by one.

  4. 4
    Move a weekly copy off-site

    Home, or cloud storage you trust. Fire and theft take the computer and the drive together.

  5. 5
    Test the restore

    Every few months, on another computer if possible, and confirm the latest invoices are there.

When to take an extra backup

  • Before installing a new version of the program.
  • Before importing or deleting a lot of data.
  • Before replacing or servicing the computer.
  • At month end and at the end of the financial year.

Should my program keep its data locally or in the cloud?

Keep the data locally on the computer if the program runs on one machine and you want it to work with no internet, accepting that backups are your job. Choose the cloud if several computers or branches need to see the same records at the same moment, and you accept that work requires an internet connection and a sign-in. The deciding question is how many computers need the data.

How do I keep my company's data safe?

Keeping company data safe rests on four habits: a personal sign-in for every employee instead of shared accounts and files; role-based permissions so each person sees only what they need; regular backups that you have actually tested restoring; and control over who can export or delete. Most data loss in small companies comes from human error or a copied file, not a sophisticated attack.

How do I make a program that works offline?

A program works offline when two things are true: it is installed on the computer itself rather than opened in a browser, and its data is stored in a local database on that machine. Then it opens, sells and prints even if the connection is down for days. The trade-off is that the data stays on that one computer, and backing it up is your own responsibility.

How do I install my program on another computer?

Copy the installer to the second computer on a USB drive, or download it from your account, then run it and follow the same steps you used on the first machine. Check first that the computer runs a supported Windows version. Note that the installer moves the program only, not locally stored data. To move data you need a backup that you restore there, or a shared cloud database.
