Those are not actual VMDK files, but stubs required to present disks during FLR. They do not consume space.

Please review the thread above for the hint regarding the error message you see.

This worked for me. I was getting a similar error copying a folder that was 18GB in size. Not exactly this error, but errors about RPC and connections when I was about 2/3 done copying. When I made the changes to the registry I was able to copy from backup fully. Thanks for posting this.

I recently have some problems restoring a lot of files (60k for 270GB) using FLR. The restore had as target the veeam server itself (physical big server).
The FLR restore was starting fine and failed at 20% with this message : Failed to open management RPC connection proxy service. Port: '6160'

We finaly found that it was due to a lack of TCP client port during the restoration. We tuned the TCP parameters creating those entry :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\Parameters:
TcpTimedWaitDelay (DWORD) = 30
MaxUserPort (DWORD) = 65534

That's it... not exacly your problem but I would check this on your veeam server if you try to launch big FLR restore.

Changing the registry to increase the number of TCP client ports solved my problem.
Thanks !

[MERGED] Veeam .flat files

Post by wijngaarden.m » Nov 06, 2017 9:13 am

Under C:\Windows\Temp folder we've found .flat files, with in the name referring to Veeam FLR.

Can anyone explain the functions of these files, and if we can delete those to clear up disk space?

I think they're used by restores and instant recoveries, and can be deleted if there are none running. I suspect they're left there if the service is restarted, or something like that, but I'm not sure. Discussed here:
