Backup failed due to "no connection with target server"

Postby Luc » Tue Apr 06, 2010 8:26 pm

Hi,

My shares on Disk Stations DS207+ and 209+II are scheduled for a daily backup to my DS207 Disk Station.
Recently I had a degraded volume on my DS207 (due to a bad sata cable) and I had to build a new JBOD volume. My backups had to start all over from scratch.
On my DS207+ I have the following shares to backup: progs: 57K files; 111 GB and data-h: 181K files; 141 GB.
On my DS209+II I have six more shares to backup daily.

When the backup has to copy a big amount of data it stops after copying a random 0-100 GB of data with the following messages (sorry, it's in Dutch):
[Kon geen verbinding maken met de doelserver = could not make a connection with target server].
Error 2010/04/06 18:34:41 admin Network Backup failed to backup task [data-h] to [ds-luc1 (192.168.110.2)]. ([30] Kon geen verbinding maken met de doelserver. Zorg ervoor dat: 1. De servernaam of IP is correct. 2. De netwerk back-up service werd ingeschakeld op de doelserver. 3. De doelserver is verbonden met een actief netwerk.)
Error 2010/04/06 18:34:41 admin Network Backup failed to backup shared folder [/data-h] to [ds-luc1 (192.168.110.2)].
Information 2010/04/06 17:07:58 admin Network Backup started to backup task [data-h] to [ds-luc1 (192.168.110.2)].

I'm not sure when this behaviour started. I noticed it for the first time with version 2.3.

Note: DS207 and DS207+ are both direct wired to a gigabit router. DS209+II is wired via a gigabit switch to the same gigabit router. The network trafic was normal during the backup failures.

Cheers,
Luc

There are a number of people having this issue, do a search and you will see the problem but no resolution so far!!!!

Robin,

As long as the backup data is up-to-date an incremental backup of a few GB mostly succeeds. It's a pain in the ... with big amounts of new data.
I reported this issue in the beta section; I thought it was solved until last week...

Cheers,
Luc

Ah

That is slightly different to me.

I can do a full backup of lots of data but subsequent backups fail with the same error message you get!

Problem solved. Firmware of Network Backup Server downgraded to version 2.2 build 0914.
