Solr Backups

Solr backups require 3 things:

• A solr cloud running in kubernetes to backup
• The list of collections to backup
• A shared volume reference that can be written to from many clouds
  • This could be a NFS volume, a persistent volume claim (that has ReadWriteMany access), etc.
  • The same volume can be used for many solr clouds in the same namespace, as the data stored within the volume is namespaced.
• A way to persist the data. The currently supported persistence methods are:
  • A volume reference (this does not have to be ReadWriteMany)
  • An S3 endpoint.

Backups will be tarred before they are persisted.

There is no current way to restore these backups, but that is in the roadmap to implement.
