A simple backup method is to connect a hard drive to your NAS device and copy the files you want to protect. Some NAS device models provide ports that allow you to connect an external hard drive, via either USB or eSATA protocols. Backup to a Directly Attached USB Hard Disk Backup is not sensitive to changes made to files by applications, and when data is restored from backup, applications using it may crash or not function properly. It is important to note that most of these backup strategies, except where specifically noted, are not application-aware. Here are common strategies you can use to backup NAS devices and protect the business from data loss and service disruption. Natural disasters-like any on-premises storage equipment, NAS devices are at risk of loss or damage from fires, floods, or other catastrophes affecting the physical facility.This can cause disk failure which will result in loss of data. Maintenance error-technicians servicing the NAS may fail to replace a malfunctioning disk, or accidentally replace the wrong disk.After power is restored, disks may not be correctly reintegrated into the RAID, leading to data corruption or data availability issues. Power outage-voltage fluctuations and overvoltage can cause problems with NAS network memory.Overheating-component malfunction or insufficient cooling can result in overheating, which can lead to drive failure.Malicious insiders might abuse their access to a NAS system to delete or tamper with NAS data. Security threats-a ransomware or other malware infection on a NAS device can result in data loss and exposure of sensitive data to attackers.
However, if multiple devices fail, the remaining devices may not be able to deal with the load, causing NAS failure.
The following are common reasons for data loss on NAS devices: The possibility of data loss is a real threat and should not be ignored. NAS devices are often used to store sensitive enterprise data. NAS Cloud Backup with NetApp Cloud Backup.Backup to a Directly Attached USB Hard Disk.We’ll review several NAS backup strategies and their pros and cons. A NAS backup strategy should also address all the additional aspects such as number of copies, retention periods and terms, different locations and platforms, and more. NAS is commonly used by enterprises for sensitive data, and it is important to set up backup for NAS devices, to ensure you can recover data in case of data loss.Ī NAS backup strategy is a technical method for backing up NAS data to another system or device.
Network-Attached Storage (NAS) is a storage system that lets computers access storage over a local area network (LAN).
