A website is a huge investment. The data collected on a website holds monetary as well as strategic value. In any circumstance, the owner cannot afford to lose any part of it. A website includes three different parts – Files (code and data of website), database and emails.
Ideally, one should take regular backups of website and keep a copy offline on their local machine. But it would be an additional support if the provider also keeps backups of your website – code, database and emails. In case of unforeseen circumstances, additional copy of backup can be beneficial.
