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:
1. 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?
thanks, Dave.

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.

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.

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.

Even if you wanted to go the route of LREP-->SnapVault-->SnapMirror, SnapMirror to Tape will support retention of the existing snapshots, where LREP will not. Something to keep in mind.

How does one use snapmirror to tape? Does it support 3rd party backup software like Veritas? Can the filer manage the tape library directly to eject and load tapes as needed. I have not seen any clear documentation about how to use snapmirror to tape in real world scenarios. Any pointers? TIA -G
There is no backup software involved. Filer writes directly to tape; you will have to manually change tapes (and mark them in order) if volume does not fit on one volume.

Veritas does support snapmirror to tape, however I havn't used it via veritas.
the command to do it directly is
snapmirror store repository_sata rst0a,rst1a where repository_sata is the volume and rst0a,rst1a the array of tape drives to use.

In the past, for large amounts of data, we've used two methods for VSM (LREP can be used for QSM, I don't think it can be used for VSM):
1.) Snapmirror to Tape 2.) Snapmirror to a 2nd _local_ volume, then take downtime to remove those disks and ship to remote site and bring online in the destination filer.

Secure Copy does copy ACL's (and shares as well). You are probably thinking of ssh/scp... but I believe the OP is talking about ScriptLogic's tool: http://www.scriptlogic.com/Products/securecopy/
SnapMirror to tape sounds like a good solution here if there's a tape device at both ends (or the tape device can travel).
