The Recovery Time Objective (RTO) answers to  “How quickly do we need to recover after a failure?”.  So, what is RTO really? It's the maximum downtime for a system, application, or service. Continue reading

Backup vs disaster recovery can be sometimes confusing: if you tell someone that your computer crashed, the first question you usually hear in response is: “Did you back up your files?” That’s the right question to ask if you’re talking only about personal data or a single computer. When your PC crashes, having a data backup available is usually all you need to restore your normal routine.

There is a number of storage classes for every need and budget in Amazon Web Services cloud storage. The cheapest method to store the backup for a long time is Amazon Glacier. However, there are two different ways to upload files to that storage: direct and using the AWS Glacier lifecycle policy. In this article, we will demonstrate why the lifecycle policy method is more practical.

Amazon S3 Glacier is a low-cost cloud storage for data archiving. In fact, S3 Glacier seems so cheap that many users chose it for storing all their backups. That may be costly, though. Why?

Because Amazon Glacier is as cheap for data storage as it’s expensive for restore. This article explains the pricing for AWS’s least expensive storage class. Continue reading

Backup as a Service (BaaS) and Disaster Recovery as a Service (DRaaS/RaaS) represent two major models ensuring high availability for the enterprise. All companies want to protect their production data against such disasters as fire, flood or human faults. And, when a disaster happens, these companies want to minimize their losses and restore data as soon as possible.

Amazon S3 Glacier is a cloud service dedicated to storing archived data that is not likely to be retrieved often. In other words, it is designed for infrequently accessed data. Glacier has a high latency of data retrieval but offers low pricing and high safety for stored archives. In this article, we are going to explain Glacier’s data uploading nuances.

Redundant array of independent disks or as it is better known — RAID — is a data storage virtualization technology that conflates multiple physical storage devices into a single logical unit. This setup enhances the integrity and reads & write speeds of the data by employing various data redundancy mechanisms, thereby giving you more certainty as to whether your data is intact at any given moment. Many people naturally wonder if RAID may altogether supersede the good old data backup; however, in this article, we will describe how RAID and backup actually complete each other rather than compete with each other.

Spoiler - no, RAID is not a backup. But it will be of a good help Continue reading

Perhaps one of the most important things in dealing with data — for both organizations and individuals — is to design sensible backup strategies to ensure that all critical data is securely stored and accessible in the event of a disaster. On the one hand, certain corporate files are absolutely crucial for the continuation of business, but on the other hand backing up applications, movies, music, and certain system files is unnecessary, as that information is easily recoverable from official sources, not to mention the spiraling out of control cloud storage fees. In this article, we set out to clarify exactly which files to back up, and which types of data should either be omitted or delegated to the image-based backup. Continue reading
