B . Standard Linux compression software and hardware compresion in the tape drive will cause bigger files on the tapes.
C . Standard Linux compression software won’t be able to write to sequential tape media.
D . Backup and restore performance will be better if we don’t introduce the compression delay into the process
E . The tape drive hardware-based compression achieves higher compression rates than either gzip or bzip2 software based compression.
