In my experience, the quickest way to move whole volumes within a filer is vol copy. If you need incremenal support, then SnapMirror also works great. The only downside to SnapMirror is it isn't free.

But do you really need "infinite incrementals" I mean you should be able to do it with minimal downtime with only a few levels. Even if you did 1 incremental per day for a week before doing the final incremental with downtime, you should be able to fit within 10 levels of incrementals. How long do you intend to strech it out?

Just curious. I've done a few of these on a Professional Serivices basis for customers and I've never used more than 7 levels.

Hello all,

We have a F720 filer where the data from one volume needs to be copied to another volume in the same filer. From the previous discussions on this mailing list, it appears that NDMPcopy 'infinite incremental' feature is the solution which provides the shortest possible downtime. What I would like to ask more experienced NetApp admins is whether there are known caveats in issuing something like:

jndmpcopy filer:/vol/vol1 filer:/vol/vol2 -sa root:<passwd> -da root:<passwd> -level i

Data ONTAP version is 6.01R1, and there is ~ 43 GB of data that needs to be moved. Any feedback on positive/negative experiences with this procedure is highly appreciated.

Robert
