Hi , I just finish the SCJD cert and just start the study of SCEA .
Now I am reading a note about
Warm backup and Cold backup .
They seem to be alike coz they all make a backup in a certain time intervals .
Then what is the real difference between them ?
Can anyone kindly tell me about this ?
Thank you in advance .
