I'm look into a problem with slow backup of a filesystem with many thousands for small files. We see high CPU load and miserable performance on restores and I've been wondering if we can tune the filesystem, or just zip the files. I guess working with many small files and tape is more of an issue with filesystem aware backups than block device ones (ufsdump).
