Task has been Rescheduled

Veeam Logoby BibieR » Tue Mar 22, 2016 6:45 am

Good Day,

I have five virtual machine all in one server running on Microsoft Server 2008 R2. I used veeam backup and replication version 7.0 to do backups for the five server both internally and externally.

currently I am receiving errors in all the backup jobs, an example for one of the VMs is " 3/22/2016 9:26:57 AM :: Task Hospital Management System has been rescheduled"
I have reverted back to the previous schedule setting but still has the same error.

Is there any other way to get rid of this problem?

Thanks in advance

Is that the only error you get? Isn't accompanied by more descriptive messages regarding snapshot creation, VSS writer, etc.? Anyway, as a first step I'd recommend updating to the latest product version, because the one you're currently using is not even supported any longer. Thanks.

To add to Vladimir's comment - this error is usually observed when there are issues with VSS provider/writer when creating a VSS snapshot. You should find more details on this in the Windows Event log of the Hyper-V server. Thanks!

v.Eremin ,there is no further message to the error. the VM processes completes correctly but each server gives the same specific error then fails. let me first by upgrading to an earlier version and see if it will help.

Updating to the most recent version might not help, as this is VSS related error. You can ask our team take a look at your logs once you have this error message for the new version of Veeam B&R.

Hi guys,

i have checked the detailed error, i missed out on.

Details: Unknown status of async operationThe shadow copy provider timed out while flushing data to the volume being shadow copied. This is probably due to excessive activity on the volume. Try again later when the volume is not being used so heavily.--tr:Failed to create VSS snapshot.--tr:Failed to perform pre-backup tasks.

[MERGED] : Backup Failed Server

Veeam Logoby paulo.neves » Fri Apr 01, 2016 12:58 pm

Hello, I recently installed Veeam Backup Free version and I was pleased with the tool.
So I started doing the backup server testing, but the copy of the Active Directory Veeam can not back up and returns the following error message:
Task AD02 Has Been rescheluded
At another point already made up that server now I'm not getting more.

My scenario:
Veeam This a virtual machine.
I created a ISCSI unit and assign the letter E: to save backups.

The other servers typically able to save.

Someone has a tip that might help?

Looks like VSS-related issue that should be better investigated with the support team. Thanks.
