I'm not sure I understand the explanation though:
Whenever a full backup is initiated it will place a pointer in the transaction log in order to understand from where the backup started. So any transaction happening,after the pointer, will be included in the backup.
Is this saying that a full backup backs up everything fully before the pointer, and then pulls the data after the pointer? Otherwise, what is the point of the pointer?
If it doesn't mean that, what does it mean? Why would a pointer be placed in the transaction log on the initiation of a full backup if it is going to backup the data before AND after the pointer?
