Hi Koen Which backup mechanism are you using ? HDFS backup setup is a lot more sophisticated, and backup repository settings made in the solr.xml manage lots of these things. The node from where you issue the command would not have any bearing on the target collections’s data that you are trying to backup. Backup will reach the designated destination, with all the data from your collection.
Thats why knowing your setup and settings for backup would help in advising you better.
