I've had the same message from tar on what were apparently erroneous
backups.  I believe the `obsolescent base-64 header' message is what you
get whenever tar's input is corrupted, which seems to be confirmed by
gzip's `crc error'.  I'd venture to say your backups are hosed; if that
arrives systematically, you might want to investigate your SCSI chain.
