I try to get some opinions about the following use case for Elixir.
I currently have shell scripts for the task of a nightly file backup.

Local commands

• mount encrypted securefs storage (“long” running interactive shell command - type password)
• rsync files to securefs mount
• stop securefs mount process
• rsync encrypted securefs storage files to remote storage

Remote commands

• rotate backups (mv & cp -al)

Now, I’m thinking about triggering all of this commands from within an Elixir application.
Is this a good idea? By heavily using System.cmd/3 and maybe Port.
Where in this use case is using Port the better choice?

The case why I would love to do all of the above in Elixir, is I want to use my existing Logger backends for e.g. log to Matrix on success, log to SMS on failure.
And I wouln’t need to configure a cronjob for running the nightly backup task.

So what are your thoughts about this?
