With the shiny new backup hard drive, I'm in the process of almost-properly backing up our servers. I'd had to resort to using rsync to mirror critical files and directories to spare hard drives on our main server - handy, but not exactly best practices. And even these drives are nearly full.
Now, I'm just finishing up with an initial backup of these files and directories to the BDE - using the Finder to manually drag stuff over into folders for each server and volume. Something like 100+ GB of important files, media and data. And the drive still has ~300GB free. I don't even want to think about how long it would have taken to burn DVD backups...
I'll be working on a script that will automate this backup, and then leave will be able to continue ignoring backups - knowing that it's all getting done behind the scenes.
