Most other storage management functions (backup, replication, HSM to some degree mirroring after the mirror has been removed from the I/O channel) work with copies of data where redundancy is more or less built in. It's like working with electrical wiring when you can turn the power off. SAN management works with active I/O configurations where real data transfers might be occurring.
