Backup exec updating catalogs hang

scaring all VMware customers about backups on v Sphere 5.1.In this post they made insinuations that backup vendors claiming support for v Sphere 5.1 were misleading their customers and putting them into unsafe recoverability conditions.

We believe this creative FUD was created just to explain why Symantec still does not support the latest v Sphere release – unlike Veeam which does support it.Symantec went on a campaign to scare people from using Veeam and more importantly to scare them from upgrading to v Sphere 5.1.Here’s a This is a very bold, public claim since VMware itself states in the KB that the issue is intermittent.Symantec even used this language in their original blog post that has since been updated.Here's a screen shot of the original that is quoted below.“During our testing with the VMware v Storage 5.1 API Symantec discovered issues* that introduce data recovery risks“ “During these weeks of close examination VMware also confirmed that any 3rd party vendor depending on the current API cannot perform consistent backups and cannot ensure a reliable recovery point” Here’s what the KB article actually says (emphasis added): "This article describes an issue with the VMware Virtual Disk Development Kit (VDDK) that may cause backup and restore operations to hang or fail.

Third-party backup vendors that are using the VMware VDDK may encounter backup or restore issues when backing up VMware v Sphere environments." So Symantec is saying the VDDK WILL cause issues and VMware is saying it MAY cause issues.The problems in the v Storage API for Data Protection (VADP) and specifically, the VDDK that Symantec pointed out do, in fact, exist.What Symantec didn’t say is that similar issues have existed in previous VDDK versions.We at Veeam took the time to let our QC double-check earlier VDDK versions, and they were able to confirm that there are issues present in previous VDDK versions that can cause VDDK calls to hang indefinitely.We are currently working with VMware to document our findings regarding previous versions of VDDK.In the meantime, all customers who are using Symantec backup products are potentially at risk.
