OMG,

nihil thx a lot for the explanation !!

u mean a lot to AO


So now finally the concept of recovery comes clear in the mind i think my calculator has only 12 digit to come with the number of bytes u mentioned above

1 GB (binary) = 2^30 = 1.073.741.824 bytes
1 GB (SI standard) = 10^9 = 1.000.000.000 bytes

1 TB (binary) = 2^40 = 1.099.511.627.776 bytes
1 TB (SI standard) = 10^12 = 1.000.000.000.000 bytes

So the difference gets bigger when drives get bigger
Sirdice
Yes
The digit Grows higher and higher depending upon the number of bytes you carry

Specially it would be a greator effect for the servers

Here i a arise with another question

how is the backup stored back for recovery

means the DATA which takes 1 GB and it can be recovered back by just a small about of (24-30) Bytes
