Troubleshooting Virtual SIRIS 2



This article explains how to troubleshoot various issues on Virtual SIRIS 2.

General Troubleshooting Steps

If you're having issues with backups, check the following places for issues:

  • The web interface for the Virtual SIRIS
  • vSphere tasks, events, and alarms for the VM we are backing up, the Virtual SIRIS appliance, and any ESXi host involved.
  • Relevant logs from guest OS that the SIRIS is backing up
    • Windows: System and Application
    • Linux: syslog, kern.log

To narrow down the problem, you can also try to run a backup with the target VM powered off.

Large Backups

On the VMware VM, a corrupted Changed Block Tracking (CBT) system can cause large backups. This kind of corruption could be caused by power loss of the ESXi host.

Network Issues

If you suspect that network related issues are affecting your agentless backups, be sure to consider the vddk transport methodas this affects the network path of the backup.

Known Issues

  • VMware has identified an issue with VMware snapshots and Microsoft Windows 2008R2 VSS framework. Since agentless backups make use of VMware snapshotting, it is important to read this article if you suspect you are having related issues.
