Data on a computer is vulnerable to all types of difficulties. Considering the same, it is important that we do not overlook the importance of regular backing-up of data regardless of the stability of the database. With a little planning and forethought, we can ensure that maintenance of the important data is continuous and hassle-free.
Depending on the volume of data entry, an appropriate backup mechanism will have to be devised. One method of achieving it will be by maintaining a backup directory in the local hard disk or the server (external storage media such as the floppy disk, zip diskette can also be used). We can have sub-directories for every day of the week under the main backup directory and regularly take data backups in the following manner depending on the day of the week.
Monday – C:\TallyBackup\Monday
Tuesday - C:\TallyBackup\Tuesday and so on till Saturday.
Note: Tally backup facility is not limited to the Hard Disk drive alone. You can backup data onto other storage devices also
The above procedure ensures that there exists a reliable data backup at any given time. In order to use that reliable data backup or bring back the data from that existing data backup you have to use the Restore option.
Important: It is preferable NOT to restore a backup onto the original data directory primarily to ensure that No data is overwritten unintentionally.
