Why shouldn’t you use the options -z and -j when using tar with a magnetic tape backup?

A.
In case of damaged tape uncompressed tar archives may allow partial recovery of the
backup

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.
