I've got an additional question concerning dump vs. tar: I seem to remember that tar has an built-in limit of 8 GB per single backup, because of some restriction in the tar file format. Is this true, and what are the limits for dump and pax? And, given that backups sizes are limited, how to best backup a 30 GB partition using 20 GB tapes? Chunk-wise, with several 'tar' runs to the same tape without rewinding, I assume? (Repartitioning into partitions with less than 8 GB each is not an option in my situation, I'm afraid.) Is there a way to let 'dump' backup less than an entire partition, such as a directory and all its subdirectories?
