Migrating files from NetApp to Linux
|

| Hi,
For various reasons I need to do this. Would like to use ndmpcopy,
in fact I have it running on my Linux system. I have ndmpd turned on,
on NetApp.
Is there an Open Source ndmpd server available for Linux?
Thanks,
Sandman

local copy?

I hope you want ndmpcopy for level 1 and level 2 for incremental. So
same can achieved by rsync on linux. So just mount netapp volume over
NFS and migrate the data by rsync command.

| The volume I wanted to migrate contained directories with lots and
lots of files in them. Rsync really cannot help because it chokes up.
Copying the files is out of the question as well because it takes so
long.
I ended up using plain old dump and restore, and it was amazingly
fast:
linuxclient# cd /volume_you_need_transfer_files_to
linuxclient# rsh filer dump 0f - /vol/volname > level0_dmp
linuxclient# restore rf level0_dmp
I ran sysstat on the filer and there was a lot of data leaving the
filer, but actually very little data coming in, so I'm assuming rsh
wasn't creating additional traffic
If my understanding of ndmpcopy is correct, this is exactly what it
does anyway, but between filers. Since my destination was a non-filer
I realized I didn't really need ndmpcopy after all.
