In our last article, we described the recent situation with many organizations were hit by the WannaCry strain of ransomware – and the possible ways of retaliation. In some cases, organizations simply chose to pay the ransom of $300 – a mere pittance compared to the value of lost data. But WannaCry was not ransomware targeting businesses; instead, it was focused on impacting individuals. Thus, the extremely low ransom. In many ways, organizations hit by WannaCry were lucky.
But the next ransomware variant may not be so nice.
In a perfect world, you would have an automated data backup and recovery solution in place for all of your data so that you never need to worry about losing data.
In the real world, however, you may sometimes experience data loss without having a data backup in place. For example, you may have a disk drive that begins to fail and contains data that is not backed up, or you may accidentally delete files that have not yet been written to a backup location.
Fortunately, it is sometimes possible to recover data in situations like this. Several free data recovery software can help you to restore data even from disks that are damaged, or after you have erased data from your file system.
This article provides an overview of free data recovery tools and explains what each one can do to help you recover data after a data loss.Continue reading →
The main aspect of every backup and recovery strategy is a balance of RTO and RPO objectives. They regard how quickly and precisely you will be able to get the data back if something goes wrong. In this article, you will learn more about the term RTO (Recovery Time Objective) and its influence on backup and disaster recovery strategies.Continue reading →
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.
But if it comes to a company, backing up data is not enough. When a company’s infrastructure is damaged or data is lost, a full disaster recovery operation needs to take place to restore operations without causing critical disruptions to the company. Disaster recovery requires much more than simply backing up files.
To understand why, you need to appreciate the difference between backup and disaster recovery, which this article explains.
It might seem that we are talking obvious things here, however, in the article you will find a couple of numbers about backup and disaster recovery.
RTO and RPO (recovery time objective and recovery point objective) are two key metrics that organizations must consider in order to develop an appropriate disaster recovery plan that can maintain business continuity after an unexpected event.
Although only one letter separates RTO from RPO, it’s important not to confuse or conflate these two metrics. Both help to determine maximum tolerable hours for data recovery, how often data backups should occur and what your recovery process should be. Both need to be considered when creating a disaster recovery plan.
There are 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 lifecycle policy. In this article, we will demonstrate why the lifecycle policy method is more practical.

Backup and archive are terms that you might hear used interchangeably. In reality, however, they are not at all the same thing. There are important differences between data backups and data archives.
Understanding these differences is crucial in order to ensure that your data processes meet your needs. Doing data backups when you instead require a data archive, or vice versa, can have very negative results when it comes time to retrieve data.
This article defines data backups and data archives and explains the differences between them.Continue reading →
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.
Microsoft Azure Cloud offers several types of scalable, high-availability storage: for tables, queues, files, blobs and Azure virtual machine disks. But what does it all really mean?
Even for an IT-specialist, it is not that easy to determine the best solution for the corporate requirements and environment. In this article, we will provide a definition for each of the Microsoft Azure storage types and give examples.Continue reading →
