We're also considering offline backup at one of our home locations. What is the best way to do this? I've considered RAID, but I live in Texas and the systems are in Phoenix, AZ. I take care of the systems remotely.
There are also continuous data protection (CDP) solutions available, which allow multiple systems to back up data on a continuous basis to a central server. However, this solution must include a remote replication element to ensure an offsite copy of your backup data exists. CDP doubled with deduplication and replication is a good choice.
Finally, there are many software-based data replication solutions to choose from and some are capable of handling reduced network bandwidth. You'll want to focus on something that requires no physical intervention because you're managing these systems remotely.
