Backup Strategy – Continuous Backup Needed?

I had an interesting conversation with Vizioncore yesterday about how backup is not as much a decision about what software to use but what process to use. In addition, this process needs to be considered from the very beginning of your virtualization architecture. With the quantity of virtual machines being used today by the SMB and Enterprise customers, the backup window has grown to nearly an all day event. What you say? An all day event? My backups happen with the window I set.
