IC3 Security and Maintenance Practice Test

Keeping a backup file on the same drive as the original copy is not advisable because it defeats the purpose of having a backup. If the original data becomes corrupted, deleted, or the drive fails, the backup stored on the same drive will also be affected and rendered useless. Effective backup strategies involve maintaining copies of data in multiple locations, particularly in different physical or virtual environments, to ensure data recovery is possible in case of an incident affecting the primary data.

In contrast, the other options represent more secure practices for data backup. Storing backups on a different computer or on an external storage device provides an additional layer of protection, while cloud storage services offer off-site backup solutions that further safeguard against data loss due to hardware failure, theft, or disasters impacting the physical location of the original data.
