Why Backup? • H 2

Why Is Backing Up Important to Us? • We want to protect our important files. – What files are important? Tax Returns, formal correspondence, personal photos and videos, • What about the operating system? – Although it is convenient to include the operating system it is not necessary. • The operating system can be restored directly over the internet 3

The Hardware • Time Capsule • External Hard Drive(s) 4

The Software • Time Machine • Boot Clones (A perfect copy of your Mac’s hard drive that will boot your computer. ) – Carbon Copy Cloner, Super. Duper • RAID (redundant array of independent disks) – A data storage virtualization technology that combines multiple physical disk drive components into a single logical unit for the purposes of data redundancy, performance improvement, or both. https: //en. wikipedia. org/wiki/RAID 5

Testing Backups • Testing your backups is an easy step to overlook, but an important step to take. Make sure your backups will be there when you need them. • The only thing worse than no backup at all is a backup that doesn’t work when you need it. • “How will I know the backup will work when I need it? ” • How to test your backups. 6

Offsite (Cloud) Backup • The best backup strategy in the world is no good if all of the backups are stored with the computer. You need to keep a set of files in a separate physical location in case your primary location is visited by fire, flood, theft or other disaster. That means sending a backup disk to another physical location. 7
