Autonomic healing
Autonomic healing improves the integrity of a backup by automatically finding and attempting to correct corrupted files in the DS-System online storage.
You can run autonomic healing on demand or configure the process to run when the DS-System starts. The following factors affect the time to complete one pass of the DS-System storage:
• Number of storage locations on the DS-System.
• Number of files on the DS-System storage locations.
• Number of autonomic healing processes running on one DS-System storage location at the same time from multiple nodes.
Autonomic healing works at the file level for all backup data and features a speed throttle that enables it to slow down when the DS-System is experiencing a high load.
NOTE: To further reduce the scan time, you can configure the autonomic healing process to validate only the metadata information for a file by setting the value of the
DeltaCheckOption advanced configuration parameter to 0. For more information, see
“Configuring the advanced settings”.
