Let's face it, you built your data center for one reason: to generate revenue. The return on investment of your hardware, software, and people really depends on what you do with that infrastructure: Is it mostly used for production activities? Or is there a lot of time when users are stymied because there’s a backup running? How much time is spent on essential—but non-production—activities like data protection?
Backup is the first line of defense, and if you’re like most organizations, you do some kind of backup daily, weekly, and monthly. To get the most out of your infrastructure and IT staff, you want to spend as little time and effort as possible on backup, but still be ready to restore fast. To that end, a common practice is to do incremental backups daily, and then once a week or so roll those incremental changes up into a synthetic full backup. This gives you a full backup that’s easier to restore from, but taking less time out of production.
