I have been working on getting backups of a Celerra written to a virtual tape library on a UNIX machine using NDMP.  According to all the documentation I've read, I should be able to pass an environment variable TYPE to specify the format of the dump.  Further, the Celerra should accept the values of "dump" and "tar".  I know the variable is getting passed, but it seems to always be ignored:

1310745654: NDMP: 4: Session 021 (thread ndmp021) < Backup type: dump >
1310745654: NDMP: 4: Session 021 (thread ndmp021) Name: BASE_DATE Value: 0
1310745654: NDMP: 4: Session 021 (thread ndmp021) Name: FILESYSTEM Value: /jh-cifs
1310745654: NDMP: 4: Session 021 (thread ndmp021) Name: HIST Value: y
1310745654: NDMP: 4: Session 021 (thread ndmp021) Name: TYPE Value: dump
1310745654: NDMP: 4: Session 021 (thread ndmp021) tape service is on a remote side, CALLER_ADDRESS 0x11b94f1.

Note the backup type is dump.

As the backup finishes, this line is shown by server_log:

1310745654: NDMP: 6: Thread nasa00 server_archive: emctar vol 1, 5 files, 0 bytes read, 272731 bytes written

It looks like server_archive is always invoked to use the emctar format, whether I pass dump or tar.  Further, the doc for server_archive says that other formats, including ustar (which is compatible with POSIX-standard tar implementations), are supported.  To me, server_archive looks a *lot* like the pax command, so I'm hoping that I can get an NDMP backup sent from the Celerra in a format other than EMC's own emctar.

Does anyone know if that's possible?

Thanks!
