In tally automatically back-up your data when loading,shutting of company in just a single click.When electricity power is suddenly off so this module save automatically data with date & time wise in your safe drive.
We will give you following features in this module :
Incremental backup stores all files changed since the last FULL, DIFFERENTIAL OR INCREMENTAL backup. The advantage of an incremental backup is that it takes the least time to finish.
For example, if a full backup was performed on Monday, Tuesday’s incremental will back up all changed files since Monday’s backup. However, Wednesday’s incremental will only back up files that have changed since Tuesday’s incremental backup and so on until another full backup is performed.
