 I am thinking of buying a second 2TB USB drive and setting it up the same way as the first one. So I could alternate the backups. One drive would be at the secret location, and the other drive would be at home. And these drives would swap place after each cycle. This would give some security about the failure of that drive, and I would have to go to the secret location only once (swapping the drives) instead of twice (picking that drive up to update the data + bringing it back to the remote location).

 Furthermore, I added scrubbing ("zpool scrub...") to the script. It ensures that the file system is consistent and that there are no bad blocks on the disk and the file system. To increase the reliability, I also run a "zfs set copies=2 zroot". That setting is also synchronized to the offsite ZFS pool. ZFS stores every data block to disk twice now. Yes, it consumes twice as much disk space, making it better fault-tolerant against hardware errors (e.g. only individual disk sectors going bad).

 Do you need Microsoft Word? Why don't you just use the Vim text editor or GNU Emacs to write your letters? If that's too nerdy, you can still use open-source alternatives such as AbiWord or LibreOffice. Larger organizations have the tendency to standardize the software their employees have to use. Unfortunately, as Microsoft Word is the de-facto standard text processing program, most companies prefer Word over LibreOffice. Same with Microsoft Excel vs LibreOffice Calc or other spreadsheet alternatives like Gnumeric. I don't know why that is; please....

Most of the programs and apps I use on them are free and open-source as well, and I am comfortable with it for over twenty years. Exceptions are the BIOSes and some firmwares of my devices. I also use Skype as most of my friends and family are using it. They are, unfortunately, proprietary software still. But I will be looking into Matrix as a Skype alternative when I have time. There are also open BIOS alternatives, but they usually don't work on my devices.

 You have better chances when you know how to manage your own server and install and manage alternatives to the big cloud providers by yourself. I have the advantage that I have work experience as a Linux Systems Administrator here. I mentioned NextCloud already. I use NextCloud for online photo and file storage, contact and calendar sync and as an RSS news feed server. You could do the same with your own E-Mail server, you can also host your own website and blog. I also mentioned Matrix as a Skype alternative (which could also be an alternative to WhatsApp, Skype, Telegram, Viber, ...). I don't know a lot about Matrix yet, but it seems to be a very neat alternative. I am ready to invest time in it as one of my future personal pet projects. Not only because I think it's better, but also because for fun and as a hobby. But this doesn't mean that I invest *all* of my personal free time in it.

 Why re-inventing the wheel? I love that a `Rexfile` is just a Perl DSL. Also, OpenBSD comes with Perl in the base system. So no new programming language had to be added to my mix for the configuration management system. Also, the `acme.sh` shell script is not a Bash but a standard Bourne shell script, so I didn't have to install an additional shell as OpenBSD does not come with the Bash pre-installed.

 I wouldn't say I like checking social media, as it can consume a lot of time and can become addictive. But once in a while, I want to catch up with my "networks". After a bad night's sleep, it's the perfect time to check your social media. Once done, you don't have to do it anymore for the next couple of days!

 And, of course, GrapheneOS is an open-source project. This is a good thing; however, on the other side, nobody can guarantee that the OS will not break or will not damage your phone. You have to trust the GrapheneOS project and donate to the project so they can keep up with the great work. But I rather trust the GrapheneOS team than big tech.

 There are some days at work you feel drained afterwards and think you didn't progress towards your goals at all. It's more challenging to shut down from work after such a day. A quick hack is to work on a quick win before the end of the day, giving you a sense of accomplishment after all. Another way is to make progress on your fun passion project after work. It must not be work-related, but a sense of accomplishment will still be there.
