I use unpriveliged LXC für everything I have running in my proxmox.

Plex, syncthing, rclone, motioneye, pyload all in seperate Lxc on the boot drive.

All data of those is on my mirror raid, including the lxc backups. The rclone lxc backs the important data onto my cloud drive.

It’s not always possible but it’s generally good practice to configure your applications to use external storage rather than file systems - MySQL/PostgreSQL for indexable data, and S3-clones like MinIO for blob storage.

One major reason for this is that these systems generally have data replication and fall over redundancy built-in. So you can have two or more physical servers, have an instance of each type of server on each, and have these stay synchronized. If one server goes down, the disks crash, or you need to upgrade, you can easily rebuild a set of redundant servers without downtime, and all you need to do is save the configurations (and take notes!)

Like I said, not always possible, but in general the more an application needs to store “user data”, the more likely it is it has the ability to use one of the above as a backend storage system. That will reduce, significantly, the amount of application servers that need to be backed up, and may reduce your need to consider using NFS etc to separate the data.

Acronyms, initialisms, abbreviations, contractions, and other phrases which expand to something larger, that I’ve seen in this thread:
