Whe using NTFS change journals, do I need to run an initlal scan then active the change journal option? What is the performance impact to a server with the NTFS Change Journal option acivated. Is the recommended setting to use NTFS change journals when possible or use scheduled scans? Which scan would normally take longer, the initial scan or a subsequent scan?

Answer / Solution

Yes, you always need an initialscan, even when using NTFS Change Journals.It 's hard to say how muchthe performance impact will be. This depends on the changes done on the observedserver. The most performance will be hold by the database server.It is only recommended touse the NTFS Change Journals, when you need always up to date size information.Normally the update scan isfaster than the initial scan, but this also depends on the number of changes onthe observed file system share.
