Why choose offsite backup? If you are backing up onsite, that’s a great start. What if your business suffers a fire, act of nature, or even a burglary? Your data could be gone with it. Offsite backup not only safe guards against this, but it allows for data restores to be done anywhere. Perfect for disaster recovery. The very best backup solution is an onsite AND offsite one. Make sure your backup solution incorporates an Exchange backup if you have an on premise Exchange server. Also make sure it includes an SQL agent and is VSS/Open File compatible.
