Last year I saw a post where Torsten explained how he is backing up C3 files by setting up folder locations in DropBox located folders. I followed his instructions and have practiced the drill of swapping out my primary laptop with my backup. It works but takes some organization. I keep a log of plugin installs and upgrades so when I turn on my backup laptop I remember to run those.
My advice to exec’s who travel is turn on their laptop the day before a trip and make sure it’s online so it catches up on updates over their fast office connection instead of on slow hotel wifi while they’re trying to work.
I run some cpu intensive plugins (Jamstix, IK Leslie, VB3 II) when I practice and sometimes, even though I’m on Windows 10 Pro and have delayed feature updates and set specific update hours, after I wake up the laptop background services plus my plugins max out the i5 3360m processor in the machine. I’m now in a habit of waking up the machine, practicing scales for 10 minutes and then practicing with C3.
If I was pro I probably wouldn’t allow my machines online!
