Data back up is most important for every accounting software .and it is recommended to keep data’s on an external storage device like CD, USB Drive etc. instead of keeping a single device, storing data’s on one or more device will give you more security against damage of storage device. There is one more good way if you are using internet at your work place. Compress the data by using any of the compressing software, like WinZip, winrar etc and send it as an attachment to your own email id, if you are following this, you don’t need a storage device, Gmail is always best to do this. What I recommend is to take back-up on a daily basis. Back up process require a couple of minutes but if you lost data you will have to work days, or weeks to re-enter the lost data.
There are two ways to take tally backup.
Open tally, go to company info menu, probably you will have to press Alt+F3 in case auto loading of company is enabled. Go to backup & Press enter
Back up screen will open
Select source, you don’t need to change this because by default this will be your data directory folder. Press enter to allow cursor to come on next field. Now enter destination directory where you wish to store data back up on your computer, let’s store on D:Backup. Press enter you will prompt to select the company from a list on your right side. If you wish to take back up of all the company, select all. Press enter to accept the screen.
Open D:Backup; Make sure there is file starting with TBK Something like “TBK900.001” Copy this file to your external storage device. You are done.
Now Let us restore the data.
Go to company info » Restore
In restoration screen Destination comes first where you want to restore data. This must be your tally data folder. By default the destination directory will be your data directory and you don’t need to change it. Now select source, where you have stored your back up files. This may vary because you might store backup files on an external storage device, so enter the drive name where back up files located. Say I:Backup.Now select companies you want to restore from a list on its right side. Press enter to accept the screen.
This is the easier method. But not recommended .Just copy the “data” folder from where tally stored data. In most case you can find data folder in tally program folder itself. If you don’t know where the data folder is located. Press F1 from the menu Gateway of Tally and fid out the address.
Restore; copy the data folder you have saved as backup. And paste it on where tally data located. And over write the previous one. If you are not familiar with windows operation
