I use Windows 2012 R2 server with the networker client. The server is VMware VM with two disks: C: and E:.. I can't make any full backup on DD160. Backups started and after some time stopped. At the client configuration the saveset was set to "ALL". So I made another tests:
1. Set saveset to :
C:\
DISASTER_RECOVERY:\
and full backup was succesfull. Below is the part of the log:
NetWorker savegroup: (notice) helios2 completed, Total 1 client(s), 1 Succeeded. See group completion details for more information.
* helios2:DISASTER_RECOVERY:\ Unable to find any full backups of the save set 'helios2:DISASTER_RECOVERY:\' in the media database. Performing a full backup.
Because log is cut/parsed, you do not see the error (nor you see where/when it breaks as you use retries). Try to save E drive using save command from client. If that works, it might be idle control session which gets killed (idle timeout) which can be addressed easily.
Anything that's got "existing connection was forcibly closed by the remote host" and you want to check out your tcp_keepalive settings. Set this down to under 1 hour on your backup server from the default of 2 hours and "refresh" your networking to pick up the change.
Historically there was a recommendation not to bring this timeout below 15 minutes. However, I think that with the significant advances in network and computing performance since that recommendation was made, I'd personally put this at 10 minutes (or a rounder number of 900 secs/900000ms). This is to come in below the half-close timeout that I think is 11 minutes 45 seconds or some similarly strange number.
Setting this on the NetWorker server should cover your environment for these kind of backup issues, though potentially you'd want it on your storage nodes as well.
