to tape or other removable storage media as they age or meet other user-defined criteria.
Remote Storage Services does this as long as you keep using the same media type. The media type for secondary storage is determined when you install Remote Storage Services, but the Removable Storage Manager (the component that manages RSS) has no option for changing the media type. This can be a problem if you're upgrading your secondary storage to, say, a higher-capacity tape format. A secondary problem in changing media is that the Remote Storage Services will not be able to read data from the old tapes since the Remote Storage feature only supports a single kind of tape at a time.
The solution to the first problem is to uninstall Remote Storage and then reinstall it after you have installed and configured the new tape devices. To do this, you must stop managing all volumes and uninstall Remote Storage. When you reinstall Remote Storage, the installation wizard will prompt you for the media type.
To use the files recorded on the old media, you will have to recall the copied files from remote storage and copy them to the new media. Since the purpose of Remote Storage is to conserve disk space by moving files to tape, you probably have more files being managed by Remote Storage than your disks can hold. Microsoft suggests recalling files in groups, say, by folders, and using a normal backup program to back them up. Then delete the data from the disk and move on to the next group of files.
Microsoft discusses this in a Knowledge Base article, "Changing Remote Storage Media Type."
