BA7034: Cloud City Immutability Old Format Upgrade Not Supported¶
Both the Cloud container and the job's Immutability configurations are enabled, but the existing cloud objects are in the old (not protected) format. Automatic upgrade is not supported. Please use a new container (or job) in order to use immutability features
| Error code | Product | Applies to |
|---|---|---|
| BA7034 | BackupAssist Classic | BackupAssist Classic v15 and later |
Description¶
If you receive this error, it means that you are using a backup job with Cloud Immutability enabled, however the target bucket/container already contains backups created without using the new Cloud Immutability format, and this is not a supported combination.
The existing bucket/container cannot be upgraded to the Cloud Immutability format.
Resolution¶
Either disable Cloud Immutability in the job (or revert to using the previous job), or change to use a new container with immutability features enabled at the provider.
See Cloud Immutability for more details on configuring your bucket/container with BackupAssist.
