I suggest storing your media on a different storage device than your Plex server.

In regards to backing up your data, see https://pve.proxmox.com/wiki/Backup_and_Restore.
In your case, backing up your media files then rebuilding your Plex server from scratch.
However, troubleshooting why your Plex server is running slow may be educational.
