I currently back up PostgreSQL and assetstore data via nightly snapshots and syncing offsite (S3, whatever), but as far as I know there's no way to atomically snapshot DSpace's Solr; ie, during the time it takes to `cp` my 8GB of Solr data, the data has changed, so the backup is not atomic and likely inconsistent. I can shut down Tomcat of course, but... that seems a bit excessive.
Upstream Solr has some discussion of backing up from read-only slaves[0], but I wanted to know if anyone had a solution for this. We're using DSpace 4.3.
