When writing to "multiple CD/DVD's, the very last thing that is written is a
record as to where each individual file is located. In order to restore from
a multiple set you have to start from the last disk, so this information can
be loaded into memory. Otherwise, how would the backup program know where to
find the individual files you wish to restore.
It has been such since the first backup program (that allowed disk
splitting) was developed - about 15 years now. Of course in the beginning
people were backing up to multiple floppies.
