The hosts-config.yml configuration file defines many settings to run the backup and restore procedure, like the location of the backup directory or the previous and new hosts in the case of a migration.
Some settings are specific to roles (bo, idx, reply).
A role has a name and a list of datasets which defines what to backup. There are some special roles that are handled specifically, but you are free to use any string as a role name.
Default settings are set at the beginning of the file, followed by specific settings related to bo, idx, and reply.
- hostname: bo1.hot-cluster
- hostname: specific-host.hot-cluster
