ReadyDR "Communication error on send"

[fn34567]

Hi,

the primary NAS is a RN3138, the one for the backup is a RN422.

The readyDR job was created via the primary NAS, a corresponding share was created on the backup NAS automatically. After starting the readyDR job a communication error pops up (after around 40min). The section from the log file is below. It seems like the primary NAS cannot write to the backup NAS. Are there any additional settings needed on the backup NAS?

Are the two NAS on the same network?

What firmware are you running on the two NAS?

Is this the first time you are using ReadyDR, or is this a new error?

[fn34567]

Yes both are on the same network

firmware is 6.10.1 - When clicking "check for updates" it tells me it is the latest version

Thats the first time using ReadyDR.

I just tried again, this time with the compression disabled. The backup is still running after 12 hours and maybe at 50%. But for space reasons it would be better to have compression ON.
