Subject [jira] Commented: (SOLR-624) patch: Don't take snapshot if there are no differences

Richard "Trey" Hyde commented on SOLR-624:
------------------------------------------

My copy of snapcleaner (-N option) from a few weeks ago in 1.3 is also doing the snap* thing,
you might want to look into that one too.

> This is similar in concept to a change I made several years ago in Solar.   Cronned snapshooters
can quickly generate a lot of snaps which will then be unnecessarily distributed to the slaves
if there hasn't been any changes in that period.
> Adds a "check" argument to make sure there where changes to the index before taking the
snap.
