Network Attached Storage (NAS) is a storage space where multiple instances can be connected to the network to share data and be used permanently. It supports NFS (Linux server, Windows server) and CIFS (Windows server) protocols, and it ranges in capacity from 500GB up to 5TB. It can be expanded according to usage, which means you can configure it according to your situation.

Generally, an instance is connected with a volume storage that can be easily expanded. However, because volume storage can be connected to only one instance, it is required to create a new volume and copy the data if there are data that need to be shared with another instance.
Through NASstorage that is used based on a network connection, you can create one or more NAS and connect them with multiple instances depending on your situation.

1. Specify the name and size of the NAS to be created and the protocol to be applied.
2. You can select an existing NAS network or create a new NAS network to connect your NAS and instances.
3. When creating a new NAS network, choose the network with the NAS network name and instances to connect to.

A snapshot refers to saving the storage condition as is, as if taking a photograph of it. Snapshot backup can be performed to back up a server, etc.

Snapshot backup means to restore the storage to the previous state when an incorrect modification is made to the data in operation, so it is similar to the System Restoration feature in Windows. It is easy to add servers using snapshots. By simply using the saved snapshot to create a “resource” in the same environment, you can build a “new resource” with the same server and storage environment that you have been using.
