Differences between conducting differential and incremental backups
When full backup is done it has copied all files, then subsequent backups in the middle of full copies period are referencing to the last full backup .
The main difference between backup types is on their connection to the archive bit, as a file component which is activated when a file is created or changed and also shows whether the file has been backed up, when it was last modified.
As we know a full backup resets the archive bit, which means that any files changed after that will be backed-up between that full backup and the next backup.
In other hand, a differential backup backup only those files that had changes after the full backup, but it doesn’t reset the archive bit, which means it will copy again on the next schedule.
As disadvantage is that the size of the differential copy will increase every time a backup is done until the next full

I am going to explain the current methods and protocols we use in a LAN environment to provide a high level of redundancy, such as EtherChannel, FHRP (First Hop Redundancy Protocols) and STP (Spanning Tree protocols). I will briefly explain how the protocols work & then discusses the latest implementations of the protocol and the environment you would expect to see them working in. The STP is a protocol that prevents loops from occurring in a switched LAN environments when a device has multiple interconnected paths. The protocols works by sending BDPU messages across in the interconnected devices, detects the loop then removes it from the topology by shutting down the port.

If this is the case then deleting everything can be the easiest way to stop. Other times, the malware is not visible to the user allowing it to travel through the system’s hard drive and damage the files. It can also be disguised as useful files.

The chapter talks about how there are “Ghosts in the machines” which could mean that what we delete is not really deleted. I find this to be scary since so many things are done on technology these days. After reading this chapter it is clear that people’s information in which they store online can be easily accessed.
