For more information, see [Supported versions](/apigee/docs/hybrid/supported-platforms#supported-versions).\n\nThis page provides an overview of restoring Cassandra in Apigee hybrid.\n\nWhy use restore?\n----------------\n\nYou can use [backups](/apigee/docs/hybrid/v1.7/cassandra-backup-overview) to restore Apigee infrastructure from the ground up in the event of\ncatastrophic failures, such as irrecoverable data loss in your Apigee hybrid instance from a disaster.\nRestoration takes your data from the backup location and restores the data into a new Cassandra\ncluster with the same number of nodes. No cluster data is taken from the old Cassandra cluster.\nThe goal of the restoration process is to bring an Apigee hybrid installation back to a\npreviously operational state using backup data from a snapshot.\n\nThe use of backups to restore is not recommended for the following scenarios:\n\n- Cassandra node failures.\n- Accidental deletion of data like `apps`, `developers`, and `api_credentials`.\n- One or more regions going down in a multi-region hybrid deployment.\n\nApigee Cassandra deployments and operational architecture take care of redundancy and fault tolerance for a single region.\nIn most cases, the recommended multi-region production implementation of hybrid means that a region failure can be recovered from\nanother live region using [region decommissioning and expansion procedures]()\ninstead of restoring from a backup.\n\nBefore you begin implementing a restore from a Cassandra backup, be aware of the following:\n\n- **Downtime:** There will be downtime for the duration of the restoration.\n- **Data loss:** There will be data loss between the last valid backup and the time the restoration is complete.\n- **Restoration time:** Restoration time depends on the size of the data and cluster.\n- **Cherry-picking data:** You cannot select only specific data to restore. Restoration restores the entire backup you select.\n\n| **Note:** When restoring an Apigee hybrid installation from backup, ensure that the backup file is created from the same hybrid version as the installation. For example, if you have a backup file created from Apigee hybrid 1.5.x, use it to restore only an Apigee hybrid 1.5.x installation. If there is version mismatch between the backup file and the hybrid installation, the restoration might not work and Apigee does not support any issues that arise because of such restoration.\n\nHow to restore?\n---------------\n\nCassandra's restoration steps differ slightly depending on whether your Apigee hybrid is\ndeployed in a single region or multiple regions. For the detailed restoration steps,\nsee the following documentation:\n\n- [Restoring in a single region](/apigee/docs/hybrid/v1.7/restore-cassandra-single-region)\n- [Restoring in a multi-region](/apigee/docs/hybrid/v1.7/restore-cassandra-multi-region)"]]
