bup remote server docker-compose config with CIFS-mounted backup store

In our previous post How to setup a “bup remote” server in 5 minutes using docker-compose we outlined how to setup your own bup remote server using docker-compose. Read that post before this one!

This post provides an alternate docker-compose.yml config file that mounts a remote CIFS directory as /bup backup directory instead of using a local directory. This is most useful when using a NAS and a separate bup server.

For this example, we’ll mount the CIFS share //10.1.2.3/bup-backups with user cifsuser and password pheT8Eigho.

Note: For performance reasons, the CIFS server (NAS) and the bup server should be locally connected, not via the internet.

# Mount the backup volume using CIFS
# NOTE: We recommend to not use a storage mounted over the internet
# for performance reasons. Instead, deploy a bup remote server locally.
