File System Tree Walk
During runtime, Data Protector creates backup statistics by a first tree walk, which briefly scans the files selected for the backup and calculates its size, so that the progress (percentage done) can be calculated. In a second tree walk, the data is written to the backup device.
Note: If millions of small files are backed up, the first tree walk could take considerable time and increase the overall runtime. The tree walk can be disabled by setting “NoTreeWalk=1” in the configuration file “<Data_Protector_home>\omnirc”.
