As someone who is wasting gigabytes upon gigabytes of data on Docker, get out of here with your stupid bullshit.
docker layers across containers are not duplicated properly if the images arent setup right which is the case for a significant amount of images.
The entire point of Docker is that way you can easily go and deploy these specific images that aren't set up right. One cannot just say, "Well, don't use those images, do something else, and do your own” because that completely defeats the point of Docker.
I had nearly 80 gigabytes of duplicated garbage. across my home system alone after after setting up things like surveillance, my nas, nitter etc.
Don't come here telling me I don't understand docker when you are the one who has no idea.
Docker is horrid for duplication. Unless you use a filesystem with good deduplication, docker can hurt a lot on your storage. and even then it still can just not work often due to due to already deduplicated extent stuff
I know this might be a bit controversial, but IMO a beginner should not self host passwords, and at least not the sole backup for photos and videos. I think self hosting them in general is good, but until you know for sure, "Ok, my back-up system is working fine, even if my stuff goes down, I have little downtime for bringing it back up".
If you can't say for sure this is you, Don't self host your passwords, bitwarden is great and encrypted so I highly doubt issues will be had there. Also make sure to use a different/seperate hosting service for pictures. I personally recommend using google drive + rsync since rsync can encrypt all your pictures.
I've seen more then a couple people fail the backup part, even when they thought they were fine before hand.
