Windows Change Journal and reparse points in folders listed in Exclude File List
I am trying to backup a file system (3 million files, 4 TB) using Accelerator and Windows Change Journal.
As some folders have reparse points pointing to data that I don't need to backup, I've put them all in the client Exclude File List. Nevertheless NetBackup insists on looking for reparse points in these folders. As a consequence, it decides not to use change journal for enumeration, hampering performance.
Is there a technical reason to worry about reparse points in a folder excluded from backup selection by user? How could I stop NetBackup from doing that? I wish to use change journal also for enumeration, but reparse point detection in excluded folders is preventing it from working correctly.
Log excerpt (folder THIS_FOLDER_HAS_A_REPARSE_POINT has been included in the client Exclude File List):
