Taking a Backup of Your Data

Taking a backup of your data at regular intervals helps retrieve your backed up data when your existing data is lost. Using Tally.ERP 9, you can easily take a backup of your company data any time and restore it when you need.

To take a backup of your data

1.    Go to Gateway of Tally > F3: Cmp Info > Backup to view the Backup Companies on Disk screen.

2.    Source - The folder path where your company data is stored. By default, the folder path of your existing company data is displayed here.

Note:

   If your company uses Tally.Server 9 to maintain data, backup has to be taken from the server data location. Click S: Server Data Loc in the Backup Companies on Disk screen, and select the server location as Source.

   If the administrator has enabled Security Control, provide authorised Tally.NET credentials to access the List of Tally.Server Data Locations.

3.    Destination - The folder path where the data backup has to be stored. You can store the backup locally on your computer, on any external storage device, or on a storage space on the network.

4.    Select the required company from the List of Companies. Select All items to back up data of all the companies.

5.    Press Ctrl+A to initiate the backup process.

The backup file is stored in the destination folder as TBK900_10000.001. Data backup taken using versions prior to Release 6.0 used to store the data in TBK900.001 format.

Note: If you are using Tally.ERP 9 Release 5.x or earlier to restore the backup file (for example, TBK900_10000.001), first rename this file to TBK900.001 and then restore.
