I have a couple of questions regarding index corruptions. 

 

1) Has anyone using Solr in a production environment ever experienced an
index corruption? If so, how frequently do they occur?

 

2) It seems like the CollectionDistribution setup would be a good way to
put in place a recovery plan for (or at least have some viable backups
of) the index. However, I have a small concern that if the index gets
corrupted on the master server, the corruption would propagate down to
the slave servers as well. Is this concern unfounded? Also, each of the
snapshots taken by snapshooter are viable full indexes, correct? If so,
that means I'd have a backup of the index each and every time a commit
(or optimize for that matter) is done, which would be awesome.

 

One of our biggest requirements for the indexing process is to have a
good backup/recover strategy in place and I want to make sure Solr will
be able to provide that. 

 

Thanks in advance!

 

Charlie
