I have a cluster with CSV 5 and DPM can't perform backup on only a few machines in the cluster, it apesenta VSS the following error:
(0x800423F3))
Well investigating deeper into the Hyper-V server virtualization encounter the following errors:
Eventvwr:
SOURCE: VSS ID: 8229
A VSS writer has rejected an event with error 0x800423f3, The writer experienced a transient error. If the backup process is retried,
the error may not reoccur.
. Changes that the writer made to the writer components while handling the event will not be available to the requester. Check the event log for related events from the application hosting the VSS writer.

So I decided to clear the "Backup (volume snapshot)" and now he backs up but does the same linux machines, saving the machine and causing downtime of it, and even if you are a linux machine with this option it can not perform the backup this because it tries utilizr VSS method (I think).
Please, anyone help-me?
thanks!
