I've spent a lot of time worrying about not having a remote backup and now I do. Here's what I'm doing: Locally, I have a copy of everything copied from all the computers to hard drives set for RAID 1 (the mirror one, so you make a copy right away). So that's really a double backup. But that won't help if there's a big fire. So you need a remote solution too. Remotely, I take the mirror'd drives and swap them out periodically, keeping one in the studio and one in a safe deposit box at the bank. For archiving old Pro Tools and DAW projects, I keep a local (upstairs in the house) copy on hard drive, and a second copy on MDisc also in the safe deposit box. MDisc purports to write data to a ceramic layer that is stable indefinitely (they say 1,000 years but whatever). The large disks can hold 100 GB. I also create daily backups of all project and Pro Tools files onto a separate drive in those computers, using Carbon Copy Cloner on the Macs and AOMEI for the PCs.
