A little over a year ago I wrote about Synology's Active Backup tool, Active Backup for Business. Their lineup of AB packages includes a total of three options. Microsoft/Office 365, Gdrive, and Business.
In this article, which was a while on the back burner, I will focus on Active Backup for Microsoft 365 (also known as Office 365 up until a while ago). With more and more users and businesses focusing on their work using the "cloud" providers such as Microsoft with their Office 365, and the COVID-19 pushing more and more people from on-premise to their homes, it is no wonder that O365 packages are becoming more interesting.
However, saying this, are you aware that O365 does not include a backup strategy? Some models do include some sort of versioning that could imply some sort of backup, but a good old fashion, off-site backup, no.
If you want to protect your business and content generated with O365 you should also consider its backup. With Active Backup, this is a matter of minutes.
