For most Indian businesses, Tally holds years of accounts, GST records, invoices and stock. Losing it — to a crashed hard disk, ransomware or an accidental delete — can mean missed filings and weeks of re-entry. The good news: a safe Tally backup takes a few minutes to set up. Here's how to do it properly, whether you use TallyPrime or Tally.ERP 9.
Step 1: Know where your Tally data lives
Tally stores each company's data in a data folder on the computer or server where Tally runs. You can see its location in Tally's data configuration settings. Note it down — this folder is what you're protecting. If several people use Tally over the network, the data lives on the main (server) computer, so that's where backups must happen.
Step 2: Take a backup with Tally's own tool
- TallyPrime: open the Data menu (Alt+Y) and choose Backup. Select the companies and a backup destination.
- Tally.ERP 9: from Gateway of Tally, open Company Info (Alt+F3) and choose Backup.
Save the backup to a different drive from the one Tally runs on — ideally a separate backup drive or network storage (NAS). A backup on the same disk disappears with it.
Step 3: Make it automatic
Backups that depend on someone remembering will eventually be missed. Two common ways to automate:
- Backup software that copies the Tally data folder to a NAS or cloud every night, after office hours when Tally is closed.
- A scheduled task on the Tally server that runs a copy job at a fixed time each night.
Whichever you use, set it to keep several days of versions, not just last night's copy. If data gets corrupted or encrypted by ransomware, you'll need a clean copy from before the problem started.
Step 4: Keep one copy off-site
Follow the 3-2-1 backup rule: your live data, a backup in the office, and one encrypted copy in the cloud or at another location. That protects you from fire, theft and ransomware that spreads across the office network.
Step 5: Test a restore
Once a month, restore a backup on a different computer (TallyPrime: Data → Restore) and open a company to check the figures. A backup only counts if you've proved you can restore it. Also make sure you know the Tally licence and version you need to open the restored data.
Common mistakes
- Backing up only to a pen drive that sits next to the computer.
- Copying the data folder while Tally is still open on another computer.
- Keeping just one backup that gets overwritten every night.
- Never testing a restore until the day it's needed.
- Leaving the Tally server exposed to the internet through remote desktop — see our ransomware checklist.
Frequently asked questions
How often should I back up Tally?
At least once every working day, plus an extra backup before year-end closing, GST filing, software updates or data repair.
Can I just copy the Tally data folder?
Only when Tally is fully closed on every computer. Copying the folder while Tally is open can give you an incomplete, unusable copy, so use Tally's own backup option or schedule the copy for after office hours.
Is a pen drive backup enough?
No. A pen drive is easy to lose, damage or overwrite. Keep one copy on a separate backup drive in the office and one encrypted copy in the cloud.
