Apache Solr 9.2.0 provides a number of features for backing up and restoring your data. You can use the backup and restore commands to backup and restore your Solr index, configuration, and other data.
To backup your Solr index, you can use the following command:
Code snippet
bin/solr backup -c
Use code with caution.
This command will create a backup of the specified collection in the backups directory.
To restore your Solr index, you can use the following command:
Code snippet
bin/solr restore -c -d
Use code with caution.
This command will restore the specified backup to the specified collection.
You can also use the BACKUP and RESTORE API commands to backup and restore your Solr index. These commands are more flexible than the backup and restore commands, and they allow you to backup and restore individual documents or ranges of documents.
For more information on backing up and restoring your Solr index, please refer to the Solr Backup and Restore documentation: https://solr.apache.org/guide/solr/latest/deployment-guide/backup-restore.html
Here are some additional things to keep in mind when backing up and restoring your Solr index:
- The backup and restore commands will only backup and restore the data in the specified collection. If you want to backup or restore all of your data, you will need to backup and restore each collection separately.
- The BACKUP and RESTORE API commands allow you to backup and restore individual documents or ranges of documents. This can be useful if you only want to backup or restore a specific subset of your data.
- When you backup your Solr index, you will also backup the configuration for the collection. This means that you can restore your index to a different Solr instance, or to a different version of Solr, and the configuration will still be compatible.
