Should hackers manage to navigate their way through your layers of protection and cause data loss, you need a physical copy of your data from which you can restore from. If the attack happened days earlier itís likely you will need to revert to earlier backups therefore having a backup rotation scheme in place can provide you with multiple data sets from which to restore from.
2. Protect against hardware and software failure
Data failure continues to be a challenge, particularly with primary storage. The very fact that data needs to regularly accessed, changed or moved exposes it to high usage risks of both hardware and software failure which could potentially lead to data loss. Secondary storage was introduced to provide an extra later of security should your primary data set fail. Storing a backup copy isnít the only consideration though when a data loss occurs the likelihood is that youíll need that data back fast. Removable technology, for example, enables you to retrieve your data quickly and effortlessly by using the highest performing storage technology available today Ė disk.
3. Protect against human failure
While automation can provide you with daily backups by using one cartridge per day, another option is aggregated backup automation which enables all slots to work together as one location.
Ultimately, the choice will lie with the business-leader. While internet and tape technologies both have their benefits, they also are susceptible downsides such as poor reliability and difficulties with removability. Ultimately, we feel removable disks are the best option and, as capacities increase in line with industry needs, will continue to be so into the future.
