Mark Miller commented on SOLR-7374:
-----------------------------------

I have the following changes already in my local copy:

* fixed formatting
* use BackupRepository.DEFAULT_LOCATION_PROPERTY

Let me take a look at the location param in solr.xml issue.

> Backup/Restore should provide a param for specifying the directory 
> implementation it should use

> Currently when we create a backup we use SimpleFSDirectory to write the 
> backup indexes. Similarly during a restore we open the index using 
> FSDirectory.open . 
> We should provide a param called {{directoryImpl}} or {{type}} which will be 
> used to specify the Directory implementation to backup the index. 
> Likewise during a restore you would need to specify the directory impl which 
> was used during backup so that the index can be opened correctly.
> This param will address the problem that currently if a user is running Solr 
> on HDFS there is no way to use the backup/restore functionality as the 
> directory is hardcoded.
> With this one could be running Solr on a local FS but backup the index on 
> HDFS etc.
