Cross-version support for Data Lake backup and restore
You can take a backup of a Data Lake that runs one version of Cloudera Runtime and restore the backup to a Data Lake running a different version of Cloudera Runtime.
Cross-version backup and restore is supported for the following Data Lake versions:
| Source (Backup) Data Lake Runtime Version | Target (Restore) Data Lake Runtime Version | Schema Upgrade Required? |
|---|---|---|
| 7.2.12 | 7.2.15 | Yes |
| 7.2.12 | 7.2.16 | Yes |
| 7.2.14 | 7.2.15 | No |
| 7.2.14 | 7.2.16 | Yes |
| 7.2.15 | 7.2.16 | Yes |
| 7.2.15 | 7.2.17 | Yes |
| 7.2.16 | 7.2.17 | No |
| 7.2.16 | 7.2.18 | Yes |
| 7.2.17 | 7.2.18 | Yes |
For these Cloudera Runtime versions, cross-version backup and restore is supported for all cloud providers and all Data Lake shapes. You can also restore your Data Lake in a new environment using the created backup from a previously created environment if the environments belong to the same tenant ID.
