Rob,

Power system only at local site, no power system at remote site.

Each VTL is connected to it's local Power system with fiber channel. The two VTL's are connected by TCP/IP. They are in different cities. How big of a pipe is needed depends on your bandwidth needs. For example, how much H/A replication is going on between the two sites, along with VTL replication, along with any VM server replication. Along with whether or not you're talking between co-lo facilities or whether or not there are employees there pounding out other Internet use.

If the VTL is doing duplication, and BRMS is not involved, this implies that the remote VTL is not even connected to the Power I, only to the source VTL.
How are the two VTLs connected, TCP/IP?
What size pipe is needed between the two VTLs?

It doesn't.

However as the volume is complete on our end if you were to restore QUSRBRM from that volume then the data is available and as the volumn ID is identical you're good to go.

You are correct that BRMS is not involved in the duplication of that volume.

Larry,

When the duplication is done by the VTL, how does BRMS know about the duplicated volume?
Currently, my dups are done by BRMS, (autodup feature).

From what I'm reading with any of the VTL solutions, BRMS would no longer be doing the dup.
Is this correct?

Paul

Cybernetics.

The VTL does the replication. It replicates directly to another Cybernetics VTL. Replication is triggered when BRMS ejects the tape from the drive at the end of the backupp.

One of the secrets to excellent remote replication is excellent deduplication. With this you send less data, MUCH less. It's the VTL that does the deduplication and Cybernetics has some of the best deduplication capability at least for IBM i tapes.

Carl,

1) Which VTL are using?
2) When you replicate to the cloud, is BRMS doing the replication or is the VTL doing the replication?

I don't often chime in on this list, but having recently made a significant change in our backup strategy, I figure I have some experience.
We are located along the South Carolina coastline, otherwise know as "hurricane alley".
We were using BRMS along with a tape library and moving tapes offsite daily, which take time, money and resources.

Last year we purchased a VTL that behaves exactly like our IBM tape library. BRMS doesn't know it's not an IBM tape library.

We replicate the daily save to another VTL in the cloud. This replication is completed within one hour after the back to on-site VTL is complete.

As a side note we do a BRMS full system save once a week and this back up is replicated to the VTL in the cloud within one hour after completion.

Here's the real magic. We have a partition in this same cloud and during our test this past year, we were able to restore our partition from the VTL to bare metal in four hours, start to finish.

We highly recommend iInTheCloud for hosting the VTL and DR partition.

This stuff really works!


Thanks,

Backup must always be looked at as insurance is.

You CAN own a home without purchasing insurance against theft, or fire, or weather. But do you?

If your home burns or is flattened by a tornado or hurricane ore *reallybigtree how can you afford to rebuild your home. NOW I don't kow you so perhaps it's possibly that you are wealthy and can rebuilt with money from your bank account or from selling another asset. But most people cannot so they pay insurance because the risk is too high.

So it is with backup. You can say OK I will risk the fact that I do not have off-site backups. Hopefully it will never happen that will need it and if I do need it because my building burned down I will simply close my business. Or I can stand the time it takes to rebuild my computer from various pieces.

But most companies cannot afford to lose their computer system. And if you cannot then you must, for the continuance of the business, have a set of data off-site, readily accessible, to recover the computer and thus continue the business.

So the decision to spend the money is exactly the decision to purchase insurance.

That's the reason to go with VTL.

VTL is definitely sounding like the way to go.

And - if you can live with some little restrictions compared to the
big ones, you get this for free but still with support...

Free is good. Getting approval to actually spend money is
challenging
at
best.
