Data backup strategy recommends three storage methods
A data backup strategy suggests keeping three copies of files, stored on two different media, with one kept offsite.
This method reduces risk of data loss from hardware failure or disasters.
Three copies of data
The strategy advises maintaining three copies of important files to ensure redundancy.
Two different media
Files should be stored on two distinct types of storage media, such as a hard drive and a cloud service.
One offsite copy
One backup should be kept in a location separate from the primary storage to protect against physical damage.
Common questions
What counts as two different media?
Two different media could be a local hard drive and an online cloud storage service.
