Hardly a storage concept embodies the RAID principle (Redundant Arrays of Independent Disks) as well as RAID 1 in which two or more hard disks are linked to save copies of data for access in case of system failure. Find out more about RAID 1 and why mirroring makes this network so special.
A Redundant Array of Independent Disks, or RAID for short, is a combination of several hard disks to form a single logical drive. Systems like these typically follows a redundant storage concept for higher security. The standard RAID 0 is an exception because it only seeks to optimize the data throughput by coupling several hard drives.
When the RAID concept was first introduced in the late 1980s, it was primarily intended as an alternative to high cost hard drives on mainframes. While the issue of cost has shifted somewhat into the background, RAID storage systems are still in demand because of their high reliability in a server environment. What’s behind the technology and what are the various RAID levels?
Server backups are the best way to save vital data from your online projects and avoid losing data. A sophisticated backup strategy including all terminal devices is essential, especially in server environments. To do so, you need reliable backup programs. In addition to software solutions and online services, which are often very expensive, free applications like rsync offer an alternative.
Robocopy is the most robust copy program in Windows 10, as it’s not affected by errors or other problems. Its high versatility is one reason for its popularity. Pretty much any backup project can be executed with the numerous options available in Robocopy. In addition to local backups, the command line tool also supports network and cloud backups.
“Data is the new oil!”. So when it comes to online businesses, loss of data means loss of capital. Important and sensitive data should be backed up at regular intervals. Thanks to free programs such as MySQLDumper you can create MySQL database backups in minutes! Once installed, you can use the software to automatize and administer backups.
With the mass of data constantly increasing, ever more efficient storage techniques are required to reduce storage requirements with as few losses as possible. For this purpose, there are two compression techniques that are currently in use. While data compression identifies and eliminates redundant information within a file, deduplication is a cross-file method that is particularly suited to...
Double is better, especially when it comes to data backups. Backups shouldn’t only contain important files like documents, tables, presentations, or videos. Generate a comprehensive storage image of your entire system with the help of image-based backup tools and completely restore it including configurations in the event of total failure. Find what makes a good image tool and which functions you...
A broken PC can be hugely frustrating for many reasons. In some situations, you may even need to replace the hardware, risking the loss of your vacation photos, documents, or important data. Creating a backup of your files can help prevent this situation. Windows 8 ships with its own tools for this purpose. We’ll provide a detailed overview of how Windows 8 backups work.
Regular backups are one of the most important factors of IT security. With Linux systems – which are often the backbone of a webserver – you can very efficiently create backup copies with the program tar. What can the archiving program do? We explain to you how tar functions and what its special features are. So that you’re able to create regular backups with tar in the future, we explain step by...
