Option 2. It’s the most robust. You’ll never lose it (provided you have the redundancy), you can use it offline, you can transfer it using a USB pen, it’s available in all platforms, including web. I’ve been using this for 8+ years, on my phone, desktop, laptop, company computer, etc. I store it on a personal cloud (and on each machine, of course, by syncing).
Great post! Very informative! I have tried to install Kinoite but it’s tricky to do with partitions. I currently have all my data/files on a big partition and install the system in a different one, and I can’t seem to install Kinoite without “formatting” the disk. Will do in the future for sure!
