Files in Long-term Storage Were Detected (code 1532)
Situation
A backup plan finishes with the following error: Files in long-term storage were detected. Current generation files were detected in long-term storage
Cause
This error appears in cases where some files required to be in hot access tiers are in long-term storage (for example, S3 Glacier-Flexible Retrieval storage class). This usually happens due to the lifecycle policy settings, when data is moved to the long-term tiers automatically after the specified retention period.
In the case of Forever Forward Incremental, the Synthetic Full mechanism is used to rebuild a full backup. Synthetic Full cannot work with data located in long-term storage. Therefore, Forever Forward Incremental is not supported if some data is in long-term storage.
Solutions
If you want to continue using long-term storage:
- Change your backup plan schedule from "Simple" (Forever Forward Incremental) schedule to "Advanced" (Recurring).
If you are ready to change your backup storage destination:
- Replace the existing storage destination with with a tier that supports Synthetic Full, then force a full backup in the backup plan.
