Re: [Veritas-bu] Need to move tape images from 7.1 master to 7.5 master

We are now using AIR with NBU 7.6.0.1 and DDOS 5.4.1.1. I think AIR was officially supported with NBU 7.6.x.x and DDOS 5.4.x.x.

Configuring AIR with DataDomain is not the most straightforward thing. There are a lot of things that are not explicitly documented. And it does put a crimp in your upgrade planning – replication destinations have to be upgraded prior to source. – And when you do bi-directional replication/AIR? Aye, there’s the rub.

AIR is Automated Image Replication.

It is part of the SLP process and utilizes the OST API to replicate the data from one Master to another and merge it in the catalog. It does it in such a way that the import is lightning quick. Once it's imported on the remote master, it's a backup image like any other.

Two issues with the suggestion - first, AIR has to be configured on the front end of the backup. Once it's backed up you can't retroactively add steps to the SLP process.

Second, the hardware has to be OST capable and also have support for AIR. I don't know if DDRs support AIR yet or not. As of about 2 years ago they didn't. Either way you would need one on the source side and one on the destination side

Dan's suggestion of just leaving it and shutting down your old environment until needed makes sense and is probably the easiest. I would recommend making backups of your catalog and keeping it handy in case it does't come back up. Otherwise, you can import anything on the old tapes and import them into your new environment if you want to go through all that trouble.

We have the scalar i6000 and it IS partitionable. Not sure which one the OP has.

Curious - What is "AIR" and how does it avoid the 2 stage import from one master to another?

"...I now have the need to move the remaining tape images from the 7.1 catalog to the 7.5 catalog."

If you can partition the Scalar (sorry- not familiar with that hardware) you could look into doing an AIR- which would mean copying the images too. Almost as annoying as re-scanning the tapes, but maybe a little less labor-intensive depending on your setup.

Otherwise you are into Symantec Professional Services territory. Outside of AIR there is no supported way for customers to merge two catalogs. I've recently looked into this as well, and its just not supported.

Not to say someone out there couldn't give you a home-baked method- but don't ask Symantec to help you out if things go sideways there. You have to pay Symantec to do the merge.
