This type of backup is an option corresponding to sites with a strong interest in not losing data in case of service interruption, for example e-commerce sites or it is not possible to lose a single data (commands, invoice, etc ...)
This type of backup is the most commonly chosen solution because it covers the needs of most sites in a reasonable way.
This type of backup is an option corresponding to static sites or almost. The content update is low and the risk of losing data too.
A good choice if you do not have an e-commerce site, forum or DMS.
This type of backup is an option corresponding to sites without content modifications: website showcase, landing page, etc.
