Small businesses rely on computers for tasks, including storing accounting and client information. Some small businesses, such as web development businesses, use computers as their main tool. Regardless of what type of small business you have, it’s important for you to back up your data on a regular basis. When disaster strikes and your business’s computer system breaks down, you still have a copy of your data available.
Direct Attached Storage
Direct attached storage devices are hard drives that you plug into a computer or server. For example, an external USB hard drive is a DAS device.
DAS devices are affordable and readily available. You can buy one online or at your local electronic store. They require little to no setup – you can plug one into your computer and start backing up your files right away. These devices are also highly portable, so it’s easy to move them off-site or bring them with you to back up your data while you’re on the road.
One downside of backing up using DAS devices is that it must be attached to the computer that you’re backing up. If you have multiple computers, you either have to get one DAS device for each computer or back up one computer after another.
Network Attached Storage
Network attached storage devices connect directly to a computer network. Some examples of NAS devices include NAS hard drives and storage area networks.
Since NAS devices are connected to the computer network, you can use them to back up multiple computers and computers at different locations, as long as they’re all connected to the same network. Some NAS devices offer redundant array of independent disks capability and store data on multiple internal disks.
Since NAS backup relies on your computer network, the backup process can be slow if you have a slow network. In addition, you may not have access to your backup when your network goes down.
Disaster Protected Storage
Disaster protected storage devices are developed for backup purposes. They’re fireproof and waterproof. If your business is located in a disaster-prone area, you may find these durable devices helpful. Disaster protected storage devices can be connected to a computer directly or to a network, so they share the same limitations as DAS and NAS devices.
Backing up your data online means that you upload your data to a file server located at a data centre somewhere through the Internet. This backup strategy allows you to store your data off-site so in case there is a fire in your office, your data is safe. Some cloud backup services even allow you to store your data at multiple data centres in different geographical areas to make sure that your data are disaster-proof.
The speed of the backup process depends on the speed of your internet connection. It can also be a problem if you have limited internet bandwidth.
