Restoring SSTables is not trivial in terms of restoring a consistent state. It depends on your failure scenario.
- Do you want to recover from unintentionally deleted data? Then it is possible that you restore the data on one node, run a repair and the data is deleted again because the tombstones are newer and you just resurrect your data again. So - you really need to know what you are doing. - Do you want to recover from complete loss? Maybe its easier to set up a backup DC. - You want to resume a dead node? Just rebuild / replace it. - You truncated a table and want to restore it? Then restoring backed up SSTables may work as disaster recovery. Although you will lose data between backup + truncate. Does that answer your question or did you mean sth completely different? 2016-11-30 21:07 GMT+01:00 Varun Gupta <var...@uber.com>: > Hi, > > We are periodically backing up sstables, and need to learn, what sanity > checks should be performed after restoring them? > > Thanks, > Varun > -- Benjamin Roth Prokurist Jaumo GmbH · www.jaumo.com Wehrstraße 46 · 73035 Göppingen · Germany Phone +49 7161 304880-6 · Fax +49 7161 304880-1 AG Ulm · HRB 731058 · Managing Director: Jens Kammerer
