The latency between VC and Hosts can cause backing up through the host directly to produce successful VSS backups whereas going through the VC causes freeze issues. In some cases, customers have scripted this service to restart prior to backup. COM+ Event System Service may need to be restarted. Exchange freeze is too I/O intensive on the back-end storage, which may necessitate that the backup time and/or the datastore the Exchange server is located on may need to be modified. VMware snapshot takes longer than 20 seconds (hardcoded Exchange VSS Writer timeout). ESX(i) host not having enough resources. #Cute writer failed network error software
Note that Veeam uses Microsoft VSS and other software vendors may use their own VSS providers/writers and that those backup solutions making successful backups are not a valid comparison. If you need to do VSS operations on a guest OS you should be doing this with only one backup product.
Ensure that you have no other backup vendor agents on the server you are backing up and if you do, uninstall them. This will prove that the issue isn’t specifically VSS-related, but is instead a combination of VSS and VMware snapshot technology. #Cute writer failed network error windows
First, make sure that you can create a windows backup of the VM using VSS. The following is a comprehensive list of resolutions that customers have used to resolve the issue: This issue is an infrastructure issue that can be difficult to narrow down. Return of snapshot information via VIM API 2ġ If a network connection to the guest OS is not available, VIX API will be used, which introduces additional latency.Ģ These steps should usually be near-instantaneous, but if the vCenter is heavily loaded or has a high latency to the ESXi hosts, the delay may be significant. Snapshot creation request via VIM API 2. VSS will only hold a freeze on the writers for up to 60 seconds (20 for Exchange), so several steps must fit within this timeframe: Veeam uses VSS to freeze applications immediately prior to creating the VMware snapshot, and then sends the thaw command as soon as snapshot creation is complete. Refers to the limit imposed by Microsoft VSS writers on the duration of a freeze. "VSSControl: Failed to freeze guest, wait timeout" To learn more about this new feature please read: If Microsoft Exchange fails to be frozen within the allowed period of time, Veeam Backup & Replication automatically fails over to the persistent snapshot mechanism. To overcome this VSS limitation, Veeam Backup & Replication utilizes the Microsoft VSS persistent snapshots technology for backup of Microsoft Exchange VMs. Starting in Veeam Backup & Replication v8 Find a Veeam Accredited Service Partner.
