Jan Høydahl commented on SOLR-16067:
------------------------------------
Would appreciate if you raise this as a question on the
[us...@solr.apache.org|mailto:us...@solr.apache.org] mailing list, until you
have conformed that it is a genuine bug.
But now that this Jira exists, please upload a larger part of server log
including stack trace.
How many shards/replicas does your collection have? Are you 100% sure that your
{{/backups}} location is a SHARED file system across all Solr nodes? This error
smells like the kind of error response you'd get if you try to backup to a
normal local disk, not a shared file system.
