When it comes to storing data, businesses have many options: online storage, offline storage, and close-up storage. Most companies use a combination of online and offline storage. However, many can reduce their costs and improve data access by adding close storage to the mix. What is proximity storage and how will it reduce costs and speed up access to data?

To better understand close storage, let's first look at what online and offline storage is. Online storage is your platform, whether it's on a local server or in a remote data center. Users access this data in real time. It is fast and easy to access. For example, in a POS system, where orders are created, they are stored in online storage. Managers can quickly run sales reports based on the data stored in the online storage system.
Offline storage is used to archive data that is no longer required for day-to-day operations, but should not yet be bypassed for various reasons, such as legal compliance or historical purposes. While you can leave this data on your platform, doing so tends to be expensive both in terms of cost and in terms of system performance. For example, do you need to store 10 years of transactions in your POS system? How often should you withdraw an order in 10 years? As the online storage system fills up with data, it is time to increase capacity. Critically, there is no point in storing all that old data on expensive, high-performance drives. By moving old data to cheaper offline storage systems, you can reduce overall storage costs while keeping your data archived if you need it for any reason.
The problem with offline storage is that while it is accessible if you need it, it is not necessarily easy to mine (source: Informed data, use proximity storage to cut costs and get quick access). For example, you may have bars stored in a warehouse in the city. To extract data, you will have to send someone to physically retrieve the tapes. As you can imagine, this is far from efficient.
Close storage is somewhere in the middle. It is generally stored in the workplace in a removable format such as CD, magnetic disk, or magnetic tape (Source: Technical Target Search Storage, Near Storage). It's a lot less expensive than online storage, but it's close. In other words, it is close to you. As such, if you need to withdraw an application 10 years ago, you will be able to do so quickly. Closed storage resides in a more active state than offline storage.
Near Storage (NLS) solutions include enhanced analytics, legacy shutdown tools, and data retention management support from SAP (source: Dolphin Corporation, data archiving and close storage for SAP ERP and BW applications). As an intermediate form of storage, closed storage can reduce storage costs by removing less-used data from more expensive primary storage to less expensive secondary storage. Accelerate access to data by placing it close to where it can be easily accessed. Instead of spending days or weeks to retrieve data offline, your nearby data can be seen in minutes.
