Best approach for Docker resilience with two hosts (lemmy.nz)

I'm running Docker on Ubuntu server; around 50 containers running, most admin via Portainer. Configuration files and small databases for container applications are stored on the local SSD, media and larger files are stored on a NAS.

NAS data and the container folders are backed up.

I have a second identical machine doing nothing. What would you recommend researching to add resilience to this setup? Top priority is quick and easy restoration should the SSD fail - everything else is relatively easy to replace.

I'll create an SSD RAID but I like the idea of a second host.

I think you can run a ceph or glusterfs cluster for sharing files in a cluster

I think 3 nodes are required for that
