Shared Folder Sync Error

[surdu]

I have two Synology NAS devices. One has been backing up to the other for a couple of years. When I connected to the server, I saw this error.

My "master" is called Media. The backup is Media2. When I look at Media2, it appears to have all the data, even recently added data, from Media. I recall setting up the backup from one NAS to another was an involved process that took some trial and error. To be honest, I don't even remember how I did it, and I don't seem to be able to find the backup configurations. I don't even remember if I did this on Media or Media2.

Any suggestions on how to resolve this issue?

When I look in the Log Center, this is what I see. I can connect to both servers on the network, so I am not sure how to diagnose this connection failure.

I just want to make sure that Media2 always has all the files from Media.

Connection fail, so I would start checking the network connections. Are both systems on the same lan?

Yes, both are on the same LAN, and I can connect to both of them. They are connected to the same LAN via Ethernet.

I'll be honest. I set up the backup three years ago. I don't even remember how I did it, and I don't seem to be able to find the backup task on the NAS. Suggestions?

I found this, which seems to indicate that the backup is working through rsync.

It seems to be inconsistent. While looking at things, this screen (below) went from success to fail to success in the space of ten minutes. I wonder if there is some rsync timeout that set too low?

What dsm versions are on both nas devices?

 

[surdu]

The destination NAS is DSM 6.2.4-25556

The source NAS is DSM 6.2.4-25556

that looks ok.
I’ probably delete the connection and re-create the task.

Okay. I'll try that. While we're at it, do you have any idea why I cannot set up QuickConnect on one of these NAS but not the other. When I try to setup QuickConnect on the one running Plex, the text box to create an ID and the Apply button are disabled. On the other NAS it worked fine.

Thanks. I had 8.8.4.4 in there, but also 10.0.1.1. I'm not sure where that came from. When I added 8.8.8.8 it worked.

I have rebuilt the backup job. I'll see if I get the error any more.
