Popular communication app Truecaller on Monday launched "Truecaller Backup" feature for Android devices which allows users to backup and restore their contacts, call history, block list and settings to Google Drive."'Truecaller Backup' has been one of the most requested features by its users and will simplify a user's transition to a new phone or SIM card by securely backing-up their contacts and settings and stored on your Google Drive, the company said in a statement.The backup file will only be available for Google Drive users to start with but the feature will be expanded to other backup storage in future. Users can also customise the frequency of backup between daily, weekly, monthly and on demand. The upgrade enables the recovery of any lost data from Google Drive which the app can restore to its last saved state.Another feature named "Truecaller Contacts" will let users search for contacts whose details they have not been saved but they have previously communicated with. The feature contains all the contacts users have called or texted which makes it for them to recall and communicate with temporary contacts without saving them in their phonebook.
