Every company needs a backup plan to recover data that has been wiped out by operator error, viruses, or hardware failures. Please define each of these terms: backup, file synchronization, restore point, and recovery disk.
What will be an ideal response?
- A backup is a copy of one or more files that is made in case the originals become damaged. A backup is usually stored on a different storage medium than the original files.
- File synchronization (sometimes referred to as "mirroring") ensures that files in two or more locations contain the same data.
- A restore point is a snapshot of your computer settings, essentially a backup of the Windows Registry.
- Most computer manufacturers often provide a way to create a recovery disk that you can use if your computer's hard disk fails. The contents and capabilities of recovery disks vary from restoring your computer to a link-new state to simply restoring user settings, programs, and data
