What exactly is EFS (Encrypted File System)?

The EFS mentions a destination folder called EFS which can store information like meid, IMEI, serial number, config, diag settings, and radio configurations, etc in an encrypted format at the document system level stores. Therefore it is very necessary for us to back-up EFS before flashing Google Android ROMs.
