I am a little fuzzy on your exact plan of action.
Given that here is what I understand what you can do.

1) netapps write in a dump format. So you can issue the dump command  on the 
netapp and write the data out to tape or read in from tape. Unless things have 
changed I believe that this is only to tape.

2) when using Netbackup with the netapp, the netbackup server controls the 
process but the netapp does the heavy lifting. The netbackup code adds label 
records to the tape. Which means that you can not just use the netapp dump 
commands to read the labels. You have to know how to skip over them, which is 
not so bad for the first tape, but can get tricky with the second tape.

3) It has been reported, but I have no first hand knowledge, that one can read 
the netapp tapes on solaris.

4) If you keep an netbackup ndmp license you should be able to use a tape drive 
attached to a netbackup media server and restore the data using ndmp to a filer 
over the network. But this still requires netbackup. The requires some special 
config work on the netbackup end of things.

Subject: [Veritas-bu] Restoring NDMP backups over the network

Greetings,

I'm trying to help out one of our other sites that is getting ready to
make some changes to their environment.  Looking through the archives
brought up a couple of questions.  This group is going to be upgrading
the filer heads and plans to do remote snapshots to our site.  This will
eliminate their use of NetBackup.  They also do not plan to attach the
tape library to the new filer like they currently have it to the old one.

I was expecting that we would be able to do restores if we connect the
tape library to the backup server and then restore any needed data over
the network to the new filer.  The messages I found in the archives
mention that NDMP dumps can only be restored back to a filer.  Here are
the questions that came up.

1.  Are all NDMP backups classified as dumps, or should we still be able
to restore selected files to another location either on a filer or
another file system?  The backups are configured for the file system
level backups, but of type NDMP.

2.  Are there any known gotchas that will either require us to connect
the library to the new filer or prevent us from doing a standard restore?

The backup version is 5.1 MP5 running on a hpux 11.11 server.  The tape
library is scsi attached.

Thanks,

Jeff
