Scheduling the System Admin process
The DS-System Admin process verifies the physical consistency of files once every 30 days. When the DS-System Admin detects a corrupted file, it moves the file and its dependents to a folder where all corrupted files are stored.
If the DS-System is part of a replication group, the DS-System Admin process attempts to recover the corrupted file from one of the other replication DS-Systems. If the DS-System Admin successfully recovers the file, no action is required by the DS-Client.
If the DS-System is not part of a replication group or the valid file is not found on a replication DS-System, the DS-System Admin process deletes the invalid data. The backup is marked as out-of-sync so the DS-Client can synchronize it later. If the file still exists on the source computer, you can back it up again to the DS-System.
You can clean recycled generations to optimize storage space based on the number of generations, the total size of recycled generations, or the age of recycled generations. For more information, see
“Optimizing storage space”.
The
RecycleSwitch advanced configuration parameter determines if delta generation recycling is performed. Recycling increases the speed of backups, but also increases the DS-System storage size until master reconstruction or optimization is performed. For more information, see
“Configuring the advanced settings”.
