Re: incremental backups not completely working?

2012-09-03 Thread Tyler Hobbs
Incremental backups are only triggered when new data is written to disk, such as a memtable being flushed or data being streamed in from a repair or move. Compaction does not create any new data, so there's no need to back up the result. On Mon, Sep 3, 2012 at 8:45 AM, wrote: > > Today I conf
