Okay thanks, that's interesting to hear. The site where we do recovery of the most critical services, and which must be done quickly, is even a little closer than yours.
I just started using vSphere Replication to sync four servers (with another four to be added) to that site. It works okay, but the sync is slow in that it's not using the available bandwidth, which apparently is expected for the way the product is designed. It's mostly a problem on the initial sync, but I also find that the RPO of 15 minutes is often not being met. How do you find the replication speed to be using SRM? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Michael Leone Sent: Friday, August 08, 2014 2:35 PM To: [email protected] Subject: Re: [NTSysADM] Fwd: Saving share permissions, and re-applying them On Thu, Aug 7, 2014 at 4:57 PM, Charles F Sullivan <[email protected]> wrote: > Exporting the Registry file probably would work, especially for the > small number of file servers you need to recover.

No, we didn't have a choice) The other site is one of our other buildings we built a small datacenter in.
