How to Backup and Restore Solr

Note: This applies to DocuShare 7.5 installations that are running Solr.

Backup using the replication API

Note: This is done using the command URL or curl commands.

Backup command

http://localhost:8983/solr/DocuShare_shard1_replica_n1/replication?command=backup&name=DS_shard1&location=C:\Solr\backup

http://localhost:8983/solr/DocuShare_shard2_replica_n2/replication?command=backup&name=DS_shard2&location=C:\Solr\backup

The "name" parameter is used to generate the backup snapshot name. It is in the form snapshot.<name>. Check that the location (C:\Solr\backup in this case) has a file named snapshot.DS_shard1 and snapshot.DS_shard2

Status of these commands can be checked here:

http://localhost:8983/solr/DocuShare_shard1_replica_n1/replication?command=details

http://localhost:8983/solr/DocuShare_shard2_replica_n2/replication?command=details
