Hi Janit, Please ask these questions the solr-user mailing list. There is no point in double posting to the dev list as well.
Looking at the stacktrace it looks like the index files are corrupted. On the backed up index can you run the CheckIndex command to see what it says. The command would look something like this - : java -cp SOLR_HOME/example/webapps/WEB-INF/lib/lucene-core-[version].jar -ea:org.apache.lucene... org.apache.lucene.index.CheckIndex /path/to/backup/data/index If the CheckIndex command says its corrupted then there is something wrong with the backup. If the CheckIndex says the index is fine then there might be something wrong with the restore process in which case we'll need to dig deeper On Tue, Mar 1, 2016 at 11:21 AM, Janit Anjaria (Tech-IT) <
