Just started to play with FD-ISR. Is there anything intrinsically different about the Primary snapshot ? After starting I made a secondary, booted to the secondary, booted back to the primary and so on. The I wondered what I would do if the primary became corrupted so booting to the secondary I deleted the primary and then asked the program to copy to a new primary. is this basically how it is supposed to work ? a kind of dual/multiple boot where if one snapshot won't work you just delete it and use one of the others or is there something special about the primary snapshot ?
