David Smiley commented on SOLR-16852:
-------------------------------------
Wouldn't commit metadata be a more general way to track a queue offset (or
similar)? This seems like information that isn't truly backup-oriented, it
seems index-oriented, and thus could be used even if backups aren't involved.
I suppose a challenge might be sharding, since not all shards are updated by
recent indexing. Nonetheless I could imagine a new mechanism to fetch the most
recent commit metadata.

> Currently backups have some properties attached such as configName,
> collectionAlias, indexVersion, etc. It would be useful to allow custom
> properties/annotations to add some information coming from the process that
> triggers the backup. For example, say you have a process that consumes from a
> queue, adds documents to Solr and then triggers a backup command, the backup
> could include the queue offset at the time of triggering the backup so that
> the application could potentially continue processing from such offset upon
> restore.
