You are going to upgrade from R77 to R80. Before the upgrade, you want to back up the system so that, if there are any problems, you can easily restore to the old version with all configuration and management files intact. What is the BEST backup method in this scenario?
B. Database Revision
D. migrate export
Explanation: 2. Snapshot Management
The snapshot creates a binary image of the entire root (lv_current) disk partition. This includes Check Point products, configuration, and operating system.
Starting in R77.10, exporting an image from one machine and importing that image on another machine of the same type is supported.
The log partition is not included in the snapshot. Therefore, any locally stored FireWall logs will not be saved.
