Keep in mind, lrep is a QTREE SnapMirror tool. I do not believe it supports volume-based SnapMirror. But SnapMirror to tape is volume based as well as shipping shelves.

LREP is another option: http://now.netapp.com/NOW/download/tools/lrep
From there, there are ways to convert SnapVault to SnapMirror and vice-versa, depending on your licensing. This peaks my interest because of your mention of using a USB drive. Think about LREP as NetApp's porting of SnapMirror/SnapVault directly to Windows, thus making devices on the Windows host available as a source/destination.
You might want to open a case with the Support Center to have all these options fully evaluated and ultimately qualified as there may be caveats with each.
Good luck.

Snapmirror to Tape. There are other methods.

Hi Dave,

Hi.
I'm planning to migrate a windows server full of data to a CIFS vol on
my
FAS3020. This volume will be snapmirrored to a remote filer over a
10Mb
line.
The data is 300GB+, and its already a fairly busy line. Time to
initialise a
mirror is going to be over a week ( and i have to throttle during the
day)
Moving the remote filer temporarily is not something I want to do.
I'm using Secure Copy
(http://www.scriptlogic.com/products/securecopy/) to
do the copying.
Is there anyway to bypass the complete 300GB snapmirror initialize?
What is
more palatable is:
- copying data to a USB disk and transporting that to the remote
site,
copying over to the mirror destination vol. OR 2. Performing the secure copy twice - transporting the server (or its
disks
for use in another server) and copying directly to the mirror
destination
vol
Any ideas or am I SOL?
If you want a snapmirror relation, you will need the snapmirror initialize, no way to circumvent it, because it needs to do a blockwise copy of the complete volume, including metadata. The metadata is stuff that isn't presented to you, it's internal to NetApp only, so you can't copy that.
If you want to use a host-based mirror (which is not the exact same as SnapMirror) I would recommend using tools that also copy the ACL's on the files, such as robocopy. Secure copy, to my knowledge doesn't copy the ACL's, which means you loose the information of who can access which data, resulting in Joe the Plummer having access to the banking details of Mr. CEO. Might not be a good idea, given the credibility of Joe these days.
HTH & HAND,
Nils
