öhm.. yes. Was it considered to be unstable?

Writing to ntfs is not unstable but (I believe) you lose the permissions which could be an issue potentially. More of a concern is performance which you have noticed. I struggled with this for a long time and the only explanation I ever found was the fact that ntfs uses journaling and doesn't write in the same way as linux formats, even though linux formats do have journaling as well, I guess it's more aggressive than ntfs's implementation. I researched this a lot and tried many different attempts to fix it including mountpoint and copying options but never really found much to make a huge difference but I know that it can bring your system to a halt sometimes. I have come to the conclusion that it is just the way that linux deals with that filesystem rather than an inherent problem as windows doesn't have such a bad performance with it, predictably, although it can be problematic there too. There are a number of things you can try, depending on how deep you want to go, but unless you need to it is better just to backup to a similar or same filesystem you are using.
Great you experience the same
. I googled, but I also don't find any good forum posts, etc. about that issue. I will reformat the device and see if it helps. I was just puzzled, because my audio was dropping out, although it should be configured to have the highest priority possible.
Right, the permission can be a problem for files in /etc, etc.

I don't know how "unlikely" that is.
I have an IDE drive from around 2000 that is still good. It's sat in a box for the last ten years. If it had been powered up regularly in that time I'm fairly certain it wouldn't be working.

They should be powered at least once per year, because of the lubrication.

I use grsync.

I use Unison to synch my laptop and desktop. That application overwrites newer files on one or the other machine. That is, I can work on a document on one computer and then its overwritten to the other.
Because I got used to using/configuring Unison I also use it to back up important directories to an external USB drive. I'd better use rsync for that though. I do not backup my complete hard drive because I don't have enough space on the external one. And I don't backup the many megabytes of internet browser cache etc.
I do not see a reason to backup applications because they don't work on a different/newer Linux distribution. Windows was great in that respect.

I have been using rsnapshot (https://rsnapshot.org/
) for the last decade or so, and it works well. It is built on top of rsync, and is very configurable. I have it running on my NAS box, backing up to an external HDD. Unfortunately my studio computer in the basement gets poor wifi reception, so I use another external HDD and rsync to back up my project files after each recording session.
I have also used merlyn's dd method from time to time, like when upgrading hardware. This method works well, but is a bit too much hassle for routine backups.

I use duplicity. It can encrypt, do incremental backups and upload to all sorts of cloud servers. I use my own nextcloud.

I have a FreeNAS system for local backups, plus SpiderOak for encrypted offsite backups.
I learned the hard way (lost 2 years' worth of photos to a brainfart) that if you only have one backup, you don't have a backup.
