No matter how efficient a computer system appears to be, there is always the possibility of a malfunction wiping out valuable data. For this reason, many companies have set up backup systems, designed to recover lost data. There are both onsite and offsite backup options, and both have certain advantages and disadvantages. Onsite storage entails storing important data on a periodic basis on local storage devices, such as hard drives, DVDs, magnetic tapes, or CDs. Offsite storage requires storing important data on a remote server, usually via the Internet, although it can also be done via direct access. Cloud backup disk space requirements can be customised to your requirements starting from 50 GB to unlimited. A fast and reliable internet connection is recommended to optimise the performance of this solution.
