Backups keep failing after 10hrs

Post by Paulo Balau »

This backup runs a little slow due to our architecture but it should not stop at 10hrs! Its for a FULL backup.
I'm writing to a QNAP NAS via CFIS. It accepts 100MB/s.
This regards to a file server having 5 disks. A few weeks ago this 100MB/s rate was shared between those this. Since some are smaller they completed sooner and after a while I had this 100MB/s only for the bigger disk (2TB).So it finished on time.
But now, for some reason, transfer rate is always ~20MB/s for all the time. :( And reaching the 10hrs job time. Fails!

I get this error:
"Additional Details: 03/11/2019 20:31:59 :: Processing SRVFSS02 Error: Invalid Signature.
Failed to write data to the file [\NASBAK01\Backups\BCK_FS\BCK_FSD2019-11-03T203159_97CD.vbk].
Failed to download disk.
Reconnectable protocol device was closed.
Failed to upload disk.
Agent failed to process method {DataTransfer.SyncDisk}."

I know permitions/authorizations are ok.

Furthermore, I tried to perform an incremental backup in order to have any kind of backup but its seems I cannot force the incremental. Even if I unselect all the "full" options it keeps trying to perform the full...

Hi Paulo,

Please upload the debug logs so our support engineers could start investigating it.

Did you find an answer to this issue? I have a Synology NAS having the same issue.

I think I found the answer:
Server Type or GPO Default Value
Default Domain Policy 10 hours
See this link: https://docs.microsoft.com/en-us/window ... ser-ticket
I am now using a Local Synology account that will not be affected by this 10 hour limit.
I will know more in 10 hours!

Using the local account solved my issue. I may try to use a Domain account sometime to see if changing the GPO to 20 hours also works. All depends if I have 10+ hours to throw away if it fails...
