Backup error or not?

Recommended Posts

Hi,

I have put a new drive in my NAS (single disk volume) and have recently been getting this message:

        Backup Set member "7-Backup - Archive": error -1116 (can't access network volume)

However, the backup says it completes with no errors or warnings! I do get an email with this message:

Script zBackup - Archive (Maggie): waiting for media

I am running Retrospect 15.1.2.100. The NAS is running a Linux client 15.1.2.101.

So we can get the messages in context, what are the Source and Destination of the Backup?

Also, why have you got the Restrospect Client software installed on the NAS?

Hi Scillonian,

To explain - my NAS is both a destination for PC backups and a source for my photo archive backups - hence installing the client on it (although I know this is not strictly necessary).

I have a dedicated PC that runs backups and Retrospect. It has a number of local disks to use for backup storage, but also my NAS. The error pops up on occasion, but not always. It didn't today but it did yesterday. No files had been added on either day. For this backup it is both the source and the destination - one volume being the source (RAID 6, 5 disks) and another volume (1 disk) as the destination. It is this 1 disk it seems to have a problem with 'finding'.

Am I correct in thinking that you are accessing the source RAID6 volume using the Retrospect Client and writing to the destination single disk volume over SMB?

What is the CPU load on the NAS during this backup?

I am wondering if the Retrospect Client is intermittently overloading the CPU.

Yes, I am accessing the RAID 6 array (source) on the NAS via the Retrospect Client - as it is setup as a Volume. I need to check if I have set the single disk (destination) as a Volume (which would then also use the Retrospect Client) or whether it is simply accessed via SMB (v3 or v2, as v1 is disabled for security reasons). As my NAS is a DS1817+ I doubt the (4 core) CPU is being overloaded, but I guess its possible.
