You use two types of storage

Better defense with 4-3-2-1
Those looking to improve on the traditional 3-2-1 strategy turn to a more robust 4-3-2-1 backup plan, which involves storing data in the cloud and creating an immutable copy of the data. With this plan:

— You have four copies of data: current production data plus three backup copies.

— You store these copies of the data in three different places; one of them should be in the cloud, and the other two can be any combination of local or offline locations.

— (local and offline).

- You have one immutable copy of the data that cannot be changed in any way by any user of the system.
How to Prevent an IT Mistake from Having a Domino Effect

Don't let your IT organization fall victim to a el salvador mobile database of errors. Preventive planning can help you stop a potential chain of errors, according to experts interviewed by InformationWeek.

A failure cascade describes a software scenario in which one bad result leads to another bad result, which then leads to a chain of failures. This is a problem that many IT managers have already encountered.

“If one mistake gets through your system of checks and balances, it can easily lead to more mistakes,” warns Troy Portillo, chief operating officer of online learning platform Studypool.

When an error is discovered, it’s always best to fix it right away. “The longer you wait for an error to be brought to your attention, the more likely it is to lead to a cascade of errors,” says Portillo. “No system is perfect, but responding quickly to a problem is the best way to avoid future problems caused by the initial error.”


An important addition to the 4-3-2-1 backup strategy is the mandatory storage of data in the cloud. In the event of a ransomware attack, if the production site is severely compromised, data replicated in the cloud can be restored to mitigate damage.

Another valuable element of the 4-3-2-1 is having a completely immutable copy. Even if the cloud has been compromised by ransomware, it is vital to have an immutable copy locked away. Ransomware can infect entire infrastructure systems; if you have a copy of your data that cannot be modified by any potential bad actor in the system, full recovery is still possible.

Today's cyber threats require serious protection to keep company data safe. Organizations are moving beyond traditional backup strategies and strengthening data protection by making more copies of data and distributing them across different storage locations. Accordingly, companies should look for multiple data storage options and the flexibility to easily create as many copies as they want, stored anywhere, regardless of the number of workloads.
