How to Restore Data in Tally Prime: Step-by-Step

Restoring Tally Prime data is a critical procedure. When you backup a company, Tally compresses the directory database files into a single backup index (usually named `TBK900_10000.001`). To read this data in Tally, you cannot simply copy it to your data folder; you must use Tally's restore utility.

Step-by-Step: Restoring Tally Prime Data from a Backup File

Before starting, make sure the backup file (the `.001` file) is saved in a local or external folder on your computer.

1. Open Tally Prime.
2. On the startup or company selection screen, press Alt+Y (Data).
3. From the dropdown list, select Restore.
4. In the Restore Destination Path field, specify the path to your active Tally data directory (where Tally stores companies, default is `C:\\Users\\Public\\TallyPrime\\Data`).
5. In the Backup Source Path field, specify the folder where your backup `.001` file is located (e.g. `D:\\TallyBackups`).
6. Tally will read the directory and display a list of all backed-up companies. Select the company you want to restore.
7. Press Enter and select Yes to confirm. Tally will extract and rebuild the company data directory.

Method 2: Manual Recovery from Raw Data Folders

If you have a backup of the raw, uncompressed company folder (e.g. a folder named `10000` containing files like `company.900`, `linkee.900`):

1. Ensure Tally Prime is completely closed.
2. Copy the entire `10000` folder from your backup drive.
3. Go to your active Tally data directory in Windows Explorer.
4. Paste the folder. If the folder already exists, choose **Replace all files**.
5. Start Tally Prime. The company will appear on the selection screen.

Resolving Version Mismatch and Data Corruption

• Version Mismatch: If the backup was taken on an older version (like Tally ERP 9) and you are restoring it in Tally Prime, the company name will show a warning: **Migration Required**. Select the company and click Migrate to update the database schema.
• Data Corruption: If Tally fails to open the restored company, try rebuilding the indexes. Press Ctrl+Alt+R on the startup screen to open the **Rewrite** tool. Select the company and confirm. This resolves structural index errors.
