[Veritas-bu] Compression
2002-12-20 09:26:42
Software compression in NBU is network compression only, the server will
uncompress the data before it puts it on tape. Hardware/tape
compression actually compresses the data onto tape.
You can use both, and in your case it may be necessary to get a full
backup over the network.
