For example, when you attempt to copy a file that's in remote storage, Windows 2000 must retrieve the file before the copy process can work. However, if you simply want to rename a file or move it to a different location on the same partition, Windows 2000 renames or moves the placeholder without having to retrieve the file. If you move the file to a different partition, the file must be retrieved, though, because moving the file to a different partition is basically the same as copying it and deleting the original. You also need to be aware of some serious compatibility issues within Remote Storage. These are related to the way that programs access the files that have been moved to remote storage.
Most programs present no problem.
However, keep in mind that Remote Storage works based on the last date that files were accessed. Therefore, programs such as backup programs, antivirus software, and indexing software tend to cause problems. For example, suppose that an antivirus program is set to scan every file on the server once a week. The program would attempt to scan the files found in remote storage and thus, because the files were accessed, Windows 2000 would move them to the hard disk and reset the time when they were last accessed. As you can see, this totally defeats the purpose of remote storage.
