Onsite backup vs offsite backup

Onsite backup and offsite backup are two popular backup types that are widely used for data protection on Server operating systems.

In general, onsite backup means storing data backup on a local storage device, such as hard drives, CDs, USB flash drives, magnetic maps, etc. While offsite backup, also known as remote backup, means back up important data from or to a remote place usually via the Internet, or directly save backups to other physical places. For example, a NAS backup, network share backup or cloud drive backup.

Both of them have merits and shortcomings, and complement each other. Generally speaking, onsite backup is easier to get started and have a quick access when disaster happens, but easier to get lost as well. Remote backup may be a little complex but provides extra protection for important data. Let’s discuss in what situations would an offsite backup matters.

In need of Windows Server offsite backup

When you make an onsite backup, the backups are usually stored near the backup source, even on the source machine. Therefore, it is vulnerable to computer virus, system failure, hard disk error, etc. What’s more, in the event of natural disaster like earthquake, flood, fire, hurricane, etc, and some bad situations like suffer from robbery or theft, the entire computer, machine, or hard drives can be damaged or get lost.

From another perspective of view, offsite backup ensures stronger security for Server. Server operating system such as Server 2012 or Server 2016 usually stores crucial business data and valuable customers’ information of especially smaller and medium companies. Keeping a remote backup helps minimize the downtime of business work and reduces economic losses to the largest extent.
