Also, while LevelDB appears to be largely an append only format, the documentation currently does not recommend live backups, presumably because there are some issues that can crop up if restoring a DB that was not cleanly shutdown.
I am guessing those issues are the ones documented as edge cases here: https://github.com/basho/leveldb/wiki/repair-notes That said, it looks like as of 1.4 those are largely cleared up, at least from what I gather from that page, and that one must only ensure that data is copied in a certain order and that you run the LevelDB repair algorithm when retiring the files. So is the backup documentation on LevelDB still correct? Will Basho will enable hot backups on LevelDB backends any time soon?
