Unable to find a recording for the slide deck posted at https://speakerdeck.com/elasticsearch/restore-in-elasticsearch-1-dot-0 An interesting scenario is described in slides 16-19 where some of the incrementals might not be usable (corrupted, missing, etc). The slides seem to suggest that a restore might still be possible using <all> the usable incrementals? ES snapshot/restore looks like an interesting approach which if I understand the slides is not subject to the issues of ordinary incremental backups... In an ordinary incremental backup, an entire set is required including the base point where you begin making incrementals. If any incrementals in a normal backup is lost, then you would be able to restore only up to before the lost incremental. Am suspecting that ES snapshots are incrementals that contain more or less completely independent data, so if any incrementals are lost you only lose the updated information in those incrementals but can restore both the updated data after the lost incrementals and the old, not updated data prior to the lost incrementals? All of the above is speculation on my part, am wondering if any of it might be true. Thx, Tony
