I have been tasked with finding some software or a service which can backup user mailboxes from a live Exchange server and SQL databases from MSSQL servers much like a Barracuda device might perform. We have looked into Amazon's S3 storage service but I am not picky. I would like to find something rather inexpensive if possible.
Have you implement such a backup strategy for Exchange/SQL?
What services/software do you know of that performs this live backup operation?
Is there a method you know of that would allow me to transfer backups of these services in a different way (offline backup or something)?
Links to products/services and any other details are greatly appreciated. Thanks in advance for your help.
