BackupData() public static method

Create a backup file This is very useful function in case you need to overwrite some file. In that case there is a chance for program to crash during the write and this would left the file corrupted, this function will create a copy of a file using config.tempName() which later needs to be deleted (after you finish your write operation). The file that is to be backed up doesn't need to exist, if it's not present the function just return false
public static BackupData ( string name ) : bool
name string Full path of a file that you want to make a backup of
