Autonomic healing vs. System Admin
Autonomic healing features advanced detection and repairing capabilities to continuously monitor the DS-System storage for data corruptions.
When corruptions are found, the autonomic healing process alerts the DS-System administrator with a notification for each backup and records the anomalies that can be fixed automatically or manually. The autonomic healing process either resolves the issue or moves the file to the trash location.
If the DS-System is part of a replication group, the autonomic healing process attempts to retrieve a correct version of the file from one of the other DS-Systems in the group. If the retrieval fails, the backup is marked as out-of-sync and the DS-Client is forced to synchronize the backup and resend a replacement for the corrupted file during the next backup session.
The Autonomic healing and System Admin processes do not delete files unless they are orphaned recycled generations. The files are moved to the trash directory under the Backup Root location.
