We are a new IT service provider. We have around 20 customers. All of them have Windows Server 2003/2008/2012. I need someone who can help me in choosing the right online backup software/solution. I would like the freelancer to know well how VSS works as I would like to do COMPLETE backup of the server and then upload the snapshot (including incremental backup) over the internet to our backup servers (Windows 2008 R2 / 2012).
I'd like the backup software to backup completely the server using Shadow Copy, then compare with latest online backup (if any), then upload the difference between them. I'd like block backup support and CHKSUM process. Something like Acronis do, but over internet.
It is my first project on [url removed, login to view] so I guess you need some more informations.
