Solr on ECS EFS

EFS Backup/Restore Procedures

EFS Backups are taken daily and automatically thanks to https://github.com/GSA/datagov-brokerpak-solr/pull/40

EFS Restores can be completed using the following procedure (originally created in https://github.com/GSA/data.gov/issues/3869):

• Turn off Harvesting and make sure no changes are happening in Solr and/or DB
• Follow AWS Documentation for restoring an EFS Backup
  • In practice, there is no need to update Access Policy roles, and EFS can be restored by simply clicking restore on the relevant backup in the backup manager (Step #4).
• Wait for backup to restore
• Perform an update-service (see below) on the solr instance referencing the restore script as the "setupLink" in the service configuration,
  • https://github.com/GSA/catalog.data.gov/blob/main/solr/restore_backups.sh
  • https://github.com/GSA/inventory-app/blob/main/solr/restore_backups.sh
• Wait for the update to complete and verify that Solr is started by inspecting the logs in the AWS Console.

Gold Nugget: See this slack discussion for information about update-service.
