The whole solution is with server-client architecture. The server-side centralized management console (AhsayCBS) can be installed either on your own backup server hosted in your datacenter, or on cloud platform such as Microsoft Azure. Users’ backup data can either be hosted on your own backup server, or on cloud storage such as Microsoft Azure, Amazon S3, etc. There are two client-side backup agents, AhsayOBM and AhsayACB. OBM is for backing up servers, databases, and VMs, and Office 365 as admin; ACB is for backing up files on desktops and laptops, as well as Office 365 as individual user. For Synology and QNAP NAS devices, we have dedicated agents for directly installation on the NAS devices to backup files with the NAS. For other brand of NAS devices, you can simply mapped the NAS as network share and back them up with AhsayOBM / AhsayACB client agent running on another machine.
