bq. So I think we do want it configurable in ReplicationHandler config, but if
it's not config'd, perhaps we could default to the first repo defined? And
local if no repos are defined? Forcing a default for this seems annoying, same
as forcing config.
Personally I think that the code under consideration is quite unrelated to
backup/restore functionality. It was added as part of SOLR-561 to implement
replication. So my suggestion is to not consider it as part of this JIRA. We
can file a separate JIRA for tracking. The backup/restore API in
ReplicationHandler already accept repository parameter in my latest patch.

> 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.
