I've been wandering about design options available with O365 backup module. Given the criteria that a company, single organization (not a service provider) needs to backup 20TB of O365 data and protect it with 321 rule, the most simple setup I can think of is:
VM with a large disk enough to download all the O365 data.
Have a single job (backup all mailboxes)
Backup the VM with Veeam VBR and copy it to a secondary repository in VBR.
However, now you have much more options with the 1.5 version. But I fail to see an inteligent way of utilizing it in a way so it would be better or more cost effective than the design I described above.
I'm sure there a lot's of customers out there setting this up these days. Has anyone thought of a more clever way to design the O365 backup infrastructure? I'd love to know how others are designing this.
