You can deal with this issue by designating a single system as a backup proxy for the entire NAS device.

In addition, in cases where a NAS device is used as a file server shared by multiple systems, the backup software on each system can create multiple backup copies of the same files.
For one, it increases network traffic because data must travel on the network from the NAS devices to the client and again from the client to the backup server. While this approach requires no special changes to the environment, it is not the most effective of the NAS backup strategies. This is essentially business as usual in terms of client-server backups, which is why it is referred to as a traditional network-based backup in this context. Traditional network-based backupĪ traditional network-based backup relies on backup agents installed on all the servers that access storage on a NAS device, and the data is sent to a backup server across the network. Here, we review four common NAS backup strategies. Unlike Microsoft Windows, Unix, Linux or macOS-based servers, which are widely supported by many backup software vendors, NAS devices require a different approach.

For that reason, you cannot install the usual backup software agents on a NAS device. For one, these appliances run proprietary operating systems optimized for storage performance. NAS appliances look like scalable file servers, but they work differently. However, with the popularity of NAS appliances, you should take a fresh look at NAS backup strategies. This remained a common backup method regardless of whether the hard-disk storage was attached to the system via a SCSI cable or Fibre Channel. As servers multiplied and environments grew larger, it became more manageable to transmit data over the network to a server that managed all the backups and the required storage media.
