I added up all the data storage in my home office, just for kicks: 652 gigabytes. Two thirds is disk-based, most of the other third is optical.
Pretty pedestrian quantities – I mostly work out of a Seagate office, so our home office is literally that.
I’m satisfied for now with my manual disaster recovery system – although I don’t rotate my offsite backups nearly often enough. As I download more video, I’m considering a move to online backup to complement my backup drive.
How much storage is in your home office? I’m sure you can top mine.
