Which backup method is described below? "After a full VM backup is created, subsequent backups are incremental. Only data blocks that have changed since the last job run are backed up. All the changes are injected into the created .vbk file to rebuild it to the most recent state of a VM."
The described backup method is a 'forever forward incremental backup'. In this method, after an initial full backup, all subsequent backups are incremental, meaning they only record the data blocks that have changed since the last backup. These changes are then merged into the original full backup file to reconstruct the latest state of the virtual machine.
The correct answer is only B. The synthetic full is backing up ALL blocks, not only changed, but the source of the not-changed block is different (previous backup, but not source)
