Operating Systems: Backups

What action should you take to prevent accidental loss of critical data that is located on a computer running Windows XP?
1. >>Use the Windows Backup utility to run regular scheduled data backups to a shared network folder. -->Correct
2. Make duplicate copies of all critical files and store them in a separate folder on the local hard disk.
3. Set the Read-only attribute on all critical data files.
4. Use the Windows Backup utility to run regular scheduled data backups to CD.

Explanation : You should use the Windows Backup utility to run regular scheduled data backups to a shared network folder to prevent accidental loss of critical data files. The files are protected unless both the local hard disk and the network server hard disk fail, which would be extremely unlikely.

You should not use the Windows Backup utility to run regular scheduled data backups to CD. The Backup utility that ships with Windows XP does not support backing up directly to CD.
You should not make duplicate copies of all critical files and store them in a separate folder on the local hard disk. This does not protect the files should the local hard disk fail.

You should not set the Read-only attribute on all critical data files as your only protective measure. Users with sufficient rights can override or reset the Read-only attribute, removing the protection. Also, this does nothing to protect against losing the files because of a hard disk failure.
