Hey Gostev, has there been any movement on this feature request? This is the one thing that's keeping us from being able to use Veeam for our large file servers.

In fact yes, there was. This feature has made it to the highest priority features list, and is on the edge of making it into 9.5 (fingers crossed).

A very big +1. I've just very recently starting playing around w/ Replication, and w/ just a simple ~14GB test VM taking upwards of half an hour to fail either direction, I'm afraid to present this as a viable alternative to VMware's SRM to management.

The only thing that scares me about this solution is that it will presumably rely on vmware CBT, which, has been notoriously unreliable in vSphere 6. I'm curious to hear what Gostev's thoughts on this are.

Re: FEATURE REQUEST - Speed Up the Planned Failback Process

I haven't read all of the posts here so hopefully this isn't a repeat. I was performing some tests doing planned fail over jobs this weekend in preparation for our yearly BCP test. I noticed the long fail back times and this gave me great concern. We have several VMs that need to be failed back with changes after our BCP test is complete. One of these is a very large file server. About 10Tb big (maybe 5 when you consider deleted blocks). There is absolutely no way I can fail that over to DR and then fail back with changes. It would take up to 48 hours to recalculate disk digests on the way back. I typically rely on Windows DFSR for file servers however it doesn't work reliably with this server for some reason.

One flaw I see in this process is that the job shuts down the replica in DR during the fail back, then it performs a replication in which it calculates disk digests.
Why does the job need to shut down the server in DR first? Why can't it simply run the replication first while keeping the server online? I know you can do that when doing a normal replication job while also calculating digests so why isn't it the same coming back? If you simply changed the process to leave the VM online in DR while the job replicates back that would help a lot. I could then leave the VM online in DR while it is replicating back. Once that first pass is done the job can shut down the VM, perform a second pass replication which should be quick and then power back up in production. It isn't perfect but it is better than hours or even days of down time just to do a fail back operation.

Have you thought about replicating failovered VMs back and then executing planned failover operation for them? That should allow you to achieve the described scenario. Thanks.

Yea that was going to be my next test. Just do a planned fail over then a permanent fail over to DR and then reverse the process.

Correct, that approach should allow you to achieve more or less the same goal you're after. Also, it should minimize time needed to transfer final changes. Thanks.

Is there any update as to whether the feature request mentioned in this thread will be implemented in Veeam 9.5?

As far as I know, this was postponed until the next major release.

It didn't make it into release, having been superseded by features with higher priority. Thanks.
