How can I reduce the equipment and management costs of backup for my customers in their ROBO sites?
Where network bandwidth permits, a centralized data protection model is the key to eliminating ROBO backup costs. There are many options like backing up directly across the metropolitan area network (MAN)/WAN to a hub or central site. But if your connectivity lacks the bandwidth necessary for backup traffic, a fairly new option has become available. Data deduplication paired up with replication allows you to perform a backup of all your data once, and then subsequent backups only send blocks or chunks of data that changes from day to day. The result is that just a fraction of data is sent over the MAN/WAN to the central site each night.
