That's a poser. HSM will move the files to more-or-less permanent tape storage, but that won't alleviate the interminable directory scan that still must be done. (This use of HSM would make large-scale restores very fast, however.) One off-the-wall suggestion: move the files (if possible) to a Windows system that has an NFS-exported filesystem that you set a mount point to on the Sun box. (Microsoft's UNIX Services for Windows, which is free nowadays, works rather well in this aspect.) Use the Windows TSM client (which does have journaling) to back up your files. You'll get a performance hit if you concurrently access a large number of files, and a downed NFS connection (for whatever reason) won't do you any good, either. -- Mark Stapleton
