Varun Thacker commented on SOLR-6637:
-------------------------------------
bq. How do we know that is going to work with any DirectoryFactory impl?
You're right. It should stay the way it was originally - {{tmpIndex =
solrCore.getDataDir() + tmpIdxDirName;}} - The HDFS tests rightly fail
otherwise.
Also this got me thinking that backups or restores won't work when using
HDFSDir since we write out the backup index using SimpleFSDirectory. I will
test it out and create another Jira for it.
Should we add HDFSDir to the list of directories in LuceneTestCase?

> We have a core backup command which backs up the index. We should have a
> restore command too.
> This would restore any named snapshots created by the replication handlers
> backup command.
> While working on this patch right now I realized that during backup we only
> backup the index. Should we backup the conf files also? Any thoughts? I could
> separate Jira for this.
