Re: Solr backup no longer writes to a UNC path

[Jan Høydahl <ja...@cominvent.com>]

Hi,

That's right. UNC paths are always disallowed since 8.6. See https://solr.apache.org/guide/8_6/solr-upgrade-notes.html#solr-8-6 and https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/core/SolrPaths.java#L64
Solution is to mount the remote server as a drive letter on the Solr hosts.
