Backing up the indexes to a HDFS filesystem

[S G <sg...@gmail.com>]

Hi,

I have a question regarding the documentation at
https://cwiki.apache.org/confluence/display/solr/Making+and+Restoring+Backups
for backing up the indexes to a HDFS filesystem

1) How frequently are the indexes backed up?
2) Is there a possibility of data-loss if Solr crashes between two backups?
3) Is it production ready?
4) What is the performance impact of backup?
5) How quick are the restores? (i.e some benchmarking of time vs index size)


Thanks
SG

Your question is better suited for the solr-user@lucene mailing list ...
not the dev@lucene list.  The dev list is for discussing development of
the internals of Solr and the Lucene Java library ... it is *not* the 
appropriate place to ask questions about how to use Solr or the Lucene 
Java library when developing your own applications.  Please resend your 
message to the solr-user mailing list, where you are likely to get 
more/betterresponses since that list also has a larger number of subscribers.
