Alternative to the NAS
NAS
Network Attached Storage (NAS) is a great low-cost tool for storing your data like backups (single files / folders or entire operating system images). Thanks to its connection (ethernet or wifi) with the local network (LAN) it is possible to easily copy the contents from your PC or server to the NAS using manual and / or automatic systems.
So why is not the NAS the reliable solution for storing my backups?
Although it is cheap and very easy to install, configuring it and using it presents some critical issues that do not make it ideal in professional work environments where data is a critical component and the backup and restore process must be absolutely guaranteed. Let’s see some examples together:
DISADVANTAGES OF BACKUP ON NAS
♦ Theft: typically the NAS are physically located inside the company (office, CED, etc.), in the same building where the data are stored that they keep the backup therefore in case a company should suffer the theft of the equipment the latter would lose both the original data present in the computers / servers and their backup contained in the NAS;
♦ Damages: Catastrophic events (earthquakes, tsunamis, tsumamis, floods, fires, etc) could damage the company’s computer equipment, destroying both the original data and the backups stored on the NAS;
♦ Ransomware: the latest variants of ransomware are able to encrypt the content of the data stored in the NAS, which makes this tool ineffective because the backup would be in turn compromised and its data not usable.
Do not limit yourself to the NAS to save your data, save them in the Cloud with the BaaS services (Backup as a Service)
What are the countermeasures to protect your data?
ADVANTAGES OF THE BACKUP ON CLOUD
♦ Physical protection: keeping your backups on the Cloud means relying on Cloud Providers who, thanks to their Datacenter, are able to guarantee the physical security of the data, also in compliance with the ISO certifications;
♦ Cloud: The Cloud by its nature allows to segregate data in order to protect the backups from ransomware viruses and all those activities (voluntary or involuntary cancellations) that constitute a threat to the data;
♦ Scalability: the size reserved for backup can easily be increased to adapt to continuous business changes.
