As another noted, use the -z option to get gzipping.  "man tar" for
more info.

As for the "-ML 650000", I think that works only on tapes, where you
change the media.  So if you told it to write to /dev/sometape
(instead of backup.tar), it still expects to write the next volume to
/dev/sometape, so, in the same way, it (reasonably) continues writing
to backup.tar.

I think you need another solution to your multi-volume file approach.
