Without the need for backup client intervention, NAS devices can send data directly to a tape device or backup server over the network. Network Data Management Protocol (NDMP) is a protocol created specifically for NAS device backups. However, when NAS devices are also used to store application-specific data, this method is ineffective. In this case, using a proxy means that a system acting as a backup client can handle backups of the entire NAS device. You can designate a single system as a backup proxy for the entire NAS device to solve this problem. In addition, when using a NAS device as a file server shared by multiple systems, the backup software on each system can create multiple backup copies of the same file. First, it increases network traffic since data must be transferred from the NAS device to the client over the network, and then from the client to the backup server.

In terms of client-server backup, this is essentially the same as usual, which is the reason for that it is called traditional web-based backup.Īlthough this method does not require any special changes to the environment, it is not the most effective NAS backup strategy. Traditional network-based backup relies on backup agents installed on all servers that access storage on the NAS device, and data is sent to the backup server over the network. Here are four common NAS backup strategies. Therefore, you cannot install regular backup software agents on your NAS device. These devices run proprietary operating systems optimized for storage performance. NAS devices look like scalable file servers, but they work differently. This streaming from the NAS backup server allows you to stream content from the NAS to any supported playback device (TV, console, set-top box). Many NAS server services include multimedia streaming protocols. Other sharing technologies like FTP (File Transfer Protocol) and SFTP (Secure File Transfer Protocol) are also included in NAS devices.Īlso see: How to Set up an SFTP Server in Windows Using OpenSSH You are allowed to share files on the NAS backup server with anyone attached to the Internet through a Web browser or mobile phone. NAS devices have many features that make it easy to share data files.
