self hosted git repository.

I setup gitea on my server and use it to track version changes of all my scripts.

And I use a combination of the wiki and .md (readme) files for howto’s and any inventory I’m keeping, like IP addresses, CPU assignments etc.

But mainly it’s all in .md formatted with markdown.

I do this at the file system level, not the file level, using zfs.

Unless the container has a database, I use zfs snapshots. If it has a database, my script dumps the database first and then does a ZFS snapshot. Then that snapshot is sent via sanoid to a zfs disk that is in a different backup pool.

This is a block level backup, so it only backs up the actual data blocks that changed.

I don’t use photoprism, but have experienced similar in other docker containers. What is most likely happening is that something, like headers/ports, needs to be forwarded by NPM, usually b adding additional config to the “advanced” tab in NPM.
Sorry, I’m not familiar enough with photoprism to know what exactly needs to be added to the config, but I since nobody has replied, I thought it might at least give you a direction to search in.
