The Symbian platform provides support for the backup of data to and the restoration of data from a compatible connected PC. The subfolder within the project folder contains the backup_registration.xml file that has information about the files backup.
The HelloWorldBasic example backup registration file is as follows:
<?xml version="1.0" standalone="yes"?> <backup_registration> <system_backup/> <restore requires_reboot = "no"/> </backup_registration>
In this case, the HelloWorldBasic example defines that its system files should be backed up, and that its restoration does not require a reboot.
For more information on backing up and restoring, see Backup and Restore.
