« Does Storage Virtualization Have A New Meaning? | Main | The Brilliance Of Virtual Clouds »

After having a dig about Storage Virtualisation; I must say I like RM alot. I wish I could get my guys to move away from scripting and make more use of RM. It certainly helped us in the Exchange area. Don't suppose you could make it heterogeneous and support other vendors!


I have been using RM in our production environment for two years now and it keeps getting better! We develop and support a custom in-house app running based on SQL 2005 and running on Windows clusters, with the databases ranging from 500GB to 2TB in size. We use RM to nightly create clones of the production databases and present them to the development servers for daily development. The SQL integration and the automation of jobs has enabled me to deliver a solution for our developers that they could not do themselves because of the amount of data we are cloning each night.

We have had our issues with the product, but over all it was well worth the investment and automates a critical function in our environment. And now we can use it to automate our RecoverPoint bookmarks for SQL and VMWare! Good job guys!

Aran -- you made my day!!

Thanks so much for sharing. And I'm sure the RM team will appreciate this as well.

It might be a hidden gem, but at what point does an investor get compensated for EMC gems and at what point does he learn they are really pyrite?

EMC does a terrible job at actualizing value from their "gems."


I don't know how familiar you are with Replication Manager and it's pricing, but it really is not that much. You are basically paying for a license per host being managed, on par with license costs for backup agents from most vendors.

And it was even cheaper for us because we had a couple of old RM/SE 3.0 licenses that EMC upgraded for free to RM 5.0 licenses. They did that for all customers that had RM/SE licenses when RM 5.0 came out and RM/SE reached End Of Life.

And compensated? I didn't purchase RM to make money but to save time and effort in managing terabytes of replications and restores for our developers. In the end this saved a lot of time our developers wasted managing restores for all of our development environments.

Hmmm, now that you mention it. Thinking about all of the above we came out ahead in the end after all.

Quite the gem indeed.



I had to argue with both my EMC sales and engineering teams to keep this product as part of our new SAN/NAS architecture. They kept telling me I had enough replication products although not one would quiesce my Exchange or SQL environments for a snapshot or clone. In the end it was my money and RM was cheap. Now that it works with RecoverPoint (which I now own) and VMware (ditto and it we use RPA with it) I feel even more justified for keeping the product. Thanks to the RM team for a great job.

Reading your comment about the RM (Repliation Manager), I tend to understand that this product should do the backup/restore like a snap. However, I found the whole truth today about the latest version RM is not doing what it should be as you advertisement. The RM only replicate at a VOLUME level, not at OS level. That means, when you have a folder with all the SHARE permission and NTFS security permission. If you do a replication that folder to the mount host somewhere in another set of disks array. You CANNOT restore the SHARE permission as you said in the blog. It only restore to the NTFS security permission, but the SHARE to the folder is stripped out during the restore. That indicate that the photographer take a picture of the human face, but left lout the eyes of the image. When you print the image, you do not see the eyes of the human face. I have learned a painfull lesson about the EMC "Replication" that after retore from the RM, users need to manually recontruct the SHARE permission to every single folder in the volume.

Other cheap software like Secure Copy can do a better job as replicate the content as well as the attribute of the files/folders that it replicated.

Please revisit the function of the RM product, and I hope that you will find out the truth, and make it as it suppose to do.

Hi Tung

I'll check, but I think you are misunderstanding something basic.

Replication Manager only orchestrates the copies, it doesn't make the actual copies.

For file systems, that would be a filesystem-based mechanism (e.g. Celerra SnapSure or similar).

I'm not quite sure why you're so angry at me and insinuating that there's something "wrong" with the product.

Nothing in my blog post spoke to NTFS snaps, where did you get that from? I've read your comment several times, and I am having trouble figuring out what exactly you're trying to do, and why.

Again, I think there's a way to do what you want to do. Do you need some assistance?

Thanks -- Chuck

Does anyone know if RM is compatible with IBM's VIOS system yet which allows for virtualization of HBA's to IBM LPAR's. We own replication manager but there seems to be no support or even interest in supporting VIOS that I'm aware.


Does anyone know if you can configure replication manager to clear an archive bit (uncheck file attribute after successful backup)?
