Backing up Tally and the billing PC: a guide for restaurant owners

In many restaurants, accounts and billing run on the same counter PC. If it fails, billing stops and the books are at risk. Here is how to protect both, in steps a manager can follow.

Where Tally keeps your data

TallyPrime stores each company’s data in a folder on the computer, with one sub-folder per company, usually named with a number. That folder is what matters. The Tally software itself can be reinstalled from the internet in a few minutes. Your ledgers, vouchers and years of entries cannot.

The location depends on how Tally was installed and who set it up. Do not guess. Open TallyPrime and check the data path in its company or data configuration screen, then write that path on a piece of paper and keep it with the shop’s important documents.

Two more things to know:

• If the data folder is on a different drive or a shared computer, that is the one you need to back up.
• Tally also has its own backup option that creates a backup file of a company. It is useful, but the backup file still needs to be copied off the PC to be of any help.

The billing software’s data

Your billing or POS software also keeps a data folder, and most can produce daily exports: sales summaries, item-wise reports, tax reports. Ask your billing software vendor two questions and write down the answers:

1. Which folder holds the data?
2. How do I export the day’s sales, and where does the export file go?

Back up both the data folder and the exports. If you ever change billing software, the exports will still open in Excel even when the old database will not.

Why a pen drive is not enough

Copying the Tally folder to a pen drive is better than nothing. But it fails in predictable ways:

• Same building. The pen drive usually sits in the counter drawer, next to the PC. A fire, flood or break-in takes both.
• It gets lost. Pen drives get borrowed, misplaced or left at home.
• It gets overwritten. If the same drive is used every day, a corrupted copy can replace the last good one, and you only find out when you need it.
• It depends on someone remembering. The routine stops the week the manager is on leave.

A pen drive can be one of your copies. It should not be the only one. At least one copy should be outside the building and should happen automatically.

A daily routine for the manager

This takes about five minutes at closing time:

• Finish the day’s billing and close the day in the billing software.
• Export the day’s sales and tax reports into the shared “Restaurant Records” folder.
• Make sure all Tally entries for the day are saved, then close Tally completely. Copying data while Tally is open can produce an incomplete copy.
• Leave the PC switched on if your backup runs overnight, or confirm the backup has finished before shutting down.
• Once a week, check that the backup actually ran. Look at the date of the latest copy, not just whether a backup app is installed.

The day the PC dies

If the billing PC will not start, or shows a ransom message, follow these steps:

1. Stop using the machine. If it is ransomware, unplug the network cable and switch off Wi-Fi.
2. Keep billing going on paper or a backup device. Use a manual bill book, or the billing app on a phone or tablet if your vendor supports it. Note every bill so it can be entered later.
3. Get a working computer. A new PC, a repaired one, or a spare laptop for now.
4. Reinstall the software. Install TallyPrime and your billing software. Your vendor and Tally partner can help with licences.
5. Restore the data from your most recent good backup. Copy the Tally data folder back to the data path you wrote down, and restore the billing data as the vendor instructs.
6. Open each company and check. Look at the last few days of vouchers and the closing balances. Compare against your bank statement if possible.
7. Enter the gap. Add any bills and entries made after the last backup, from the paper records.

The more recent your last backup, the shorter step 7 will be.

Test a restore every month

A backup you have never restored is a guess. Once a month, pick a quiet hour and:

• Restore the Tally data folder from the backup to a separate test location on a different computer, not over the live data.
• Open it in TallyPrime and check that the latest entries are there.
• Open one or two billing exports and a few scanned bills.
• Write down the date, who did it, and whether it worked.

If anything fails, fix it that week, not when the PC dies. Our post on testing restores goes into more detail.

Closing note

triplicate is being built for exactly this setup. It does not plug into Tally or any billing software directly; a small Windows or Linux desktop agent, still in development, copies the folders you choose, such as the Tally data folder and the exports folder, every night. One copy stays on your PC; the other two are kept by two different storage providers you choose, one of them on another continent. Plans are prepaid with a ₹200 monthly minimum and no auto-debit; see pricing. We are in early access, so if you run a restaurant, get in touch.
