Lost or stolen data? Cue the cold sweats and panicked breathing. Unfortunately for many brands, data loss is a reality that they could face at any time. It’s all-too common that we hear about companies, large and small experiencing technology disasters: lost or destroyed data, lost devices (you never know who will pick up that iPad you left in the cab!), hacking and more. Your data is valuable, we suggest you guard it.
If you are a SysAdmin it is your solemn duty to ensure your systems run smoothly and without loss of data. Here are several technologies commonly used to keep your data backed up and available in the event that your primary systems go down.
Common Data Backup Technologies
• Cloud backup – Online data services are available for simple incremental backups of your file server, to live synchronization with your on-premises data, to colocation of your entire IT platform. Small to medium business may only need a basic backup scheme, whereas large enterprise demands might call for a fully dedicated cloud data service.
• Redundant (mirror) servers – this is pretty much a no-brainer if your data is in a “mission critical” environment. This is typically an additional physical server that performs as a live mirror, automatically taking over if your primary machine fails.
• Tape backup – If your father was a SysAdmin he probably had to change a tape cartridge in the mainframe each morning. Perhaps you do as well. While this technology has been around for decades and data transfer is often slow, it has time-proven dependability and reliability.
• DVD, Blue-ray – DVD discs offer up to 9.4 GB (double side) data storage so they are only useful for lightweight storage needs. Blue-ray discs can hold up to 50 GB (double layer) with larger capacities possible in the future. If you have modest storage needs, Blue-ray may be an economical choice for creating long-term data archives.
• Network attached storage – Typical products consist of one or more hard drives inside a dedicated network-capable device. These devices may provide a fast, economical way of adding storage to your system.
• Portable hard drives – Cheap, effective, high-capacity data storage. They typically come with USB or SATA connections for fast data transfer. If you are using them for off-premises storage and you don’t want your data to fall into the wrong hands, be sure your data is encrypted!
• USB flash drives – Also cheap and effective, much smaller but also less capacity than many portable hard drives. Useful for modest storage needs. Just like portable hard drives, be sure to encrypt important business data.
