streaming and intellisnap backups for vSAN datastore

In the following URL vSAN Support for the Virtual Server Agent with VMware (commvault.com), it is written “For Service Pack 11 and later, the Virtual Server Agent (VSA) provides support for streaming backups, IntelliSnap backups, and restores of virtual machines on VMware Virtual SAN (vSAN) datastores.”In the case of  VMware vSAN, what is the difference between streaming & Intellisnap backups?Is the hotadd transport mode linked to Intellisnap backups and the NBD transport mode linked to streaming backups?Thanks & Regards

Intellisnap Backup Copy kills Virtual Disk Service on Server 2016 Media Agent

HiBeen plagued with this problem for a while. Support has not been able to crack it yet either. I have 4 Media Agents and 2 are using CBT and crash consistent backup options for the Intellisnap and work fine. The other 2 Media agents are also using CBT but using Application Consistent (quiesced backup) backup options for Intellisnap and these Media Agents will sometimes freeze up the Virtual Disk Service and the backupcopy fails for the remainder of the backup copies. I cannot open the process manager on the MA’s when this happens and end up have to reboot the MA to get things back on track. Not a lot of info but chucking this one out there to see if anyone had a similar experience.

Possible to restore a AD server from a vmware snapshot backup?

Hi All.In a scenario where you have Vmware snapshot backups of AD servers (2016/2019), would it be possible to do a Vmware restore of the server, and get it up and running again, if one AD server out of two has crashed? Are there any considerations or things that have to be done after the restore, before its working as a domain controller in a pair of two domain controllers again ? Or what would best practice be on a AD server running in vmware? Regards-Anders

CVVD.SYS driver may cause reboot when using Live Browse or Block Level restore using Virtual Server Agent

An edge condition was found when performing a file-level restore of a virtual machine using the Virtual Server Agent, the Access or Proxy Node may reboot due to the CVVD.sys driver that loads the backup data for browsing.The following versions are affected:FeatureRelease 22.42 to 22.49 FeatureRelease 23.29 to 23.34 FeatureRelease 24.15 to 24.20 FeatureRelease 25.0 to 25.2Some common symptoms are the CVD log will flood with NULL values and the following error will be reported for the browse on the media agent.Failed to receive browse response from MediaAgent. Please check Browse.log on MediaAgent.The Browse log on the media agent and\or access node (VSA Proxy) may indicate the following:CCvNetwork::CheckIfDataAvailable() - Thread is waiting for data on a socket. Waited for 600 sec(s). Requested wait time = no time out. Connection details : The CVVD challenge is addressed with the latest maintenance releases when applied to the Virtual Server Proxy or Access Node. These can be downloaded

Virtualize Me -Vmware question

Hi all. I have a question about Virtualize Me - Vmware. I have a physical server, which I want to make a clone of, to our Vmware environment. I do not want the cloned server to be connected to the network in anyway as its a DC server. So my question is, when the Virtualize Me process is running, will the server at any point be connected to the network for the restore process to work or is all done “offline”? Thanks-Anders

How to install vsa agent -requirements

Hello,I have installed Simpana 11.20 on commvault backup server srvbck (on this machine is also installed media agent which serves backup on Tape library)Also I have four virtual machines, vsa-agent (which is installed on Citrix virtualization platform) and another media agent htmmediaagent1 which serves backup virtual machines.The backup is located at the htmmediaagent1 server location.I should add more virtual machines(which are located on different virtualization platforms) for backupon the Tape library. Then another media agent would be used for backup srvbck… My question is:Do I need to have another vsa agent installed (on other virtualization) to back up virtual machines to the Tape library?Do I need to have a separate all agents installed on for each virtualization?Thank you!Best regards,Elizabeta

Migration of Indexing v1 to v2 for multiple pseudo-clients targetting the same VCenter

Hello !There are many helpful links and docs about VSA Indexing v1 to v2 migration, requirements and post-migration tasks.. But as of now, I have not yet found the answer to my question regarding my environment.  We have a single VMWare VCenter, lets call it VCENTER.This single VCENTER server manages multiple locations, like USA, CANADA, INDIA, etc.., where each time we have a corresponding VMWare Datacenter, with ESXes, VMs we need to backup, and MAs. In our Commvault environment so far, for internal reasons, I have created a VMWare Pseudo client for each location, like :VCENTER-USAVCENTER-CANADAVCENTER-INDIA Each point to the same VCENTER, but the VSA configuration for proxies, SPs and target VMs to backup are different as they’re pointing to the servers for each location.They were all created using indexing v1.So far I can only migrate using the indexing v1 to v2 workflow.My question is, is it possible to update only 1 of those pseudo client, like VCENTER-INDIA, AND to not affect th

VM proxy hot add mode - logs of the VSA backup process

Hi all, we are still facing the issue with failing VSA HotAdd mode backup, that ends with the error "Virtual disks needs consolidation".We know, that during the back up, the virtual disks are binded to VM proxy, a snapshot is done, but the virtual disks stay attached to the backup proxy.My question is, where to find logs from the back up process from the VM proxy. I think, in these logs it could be documented, why the virtual disks are still attached to the backup proxy VM. I have checked the log of the job, but there was no such information. Is there any log, that describes what is being done during the backup job on the VM proxy? Cheers!

Unable to restore full virtual machines for VMware client

Hello! I’m trying to do a “full virtual machine” restore of a few VMs, and I think that something is majorly wrong with the system. Disclosure that full VMs are not something we have to do very often at all.About 6 months ago we switched from using a Dell SAN that had intellisnap support in commvault via Dell Storage Manager (DSM) to a cheaper SAN (a powervault) that doesn’t have intellisnap support. So at the recommendation of our Commvault local partner that we buy our licenses through, we switched our VSA backup type from NBD/Auto to SAN.Now, for the first-ever attempt of a “full virtual machine” the restore job starts, then I immediately get an error like below.Error Code: [91:81]Description: Unable to write data to the virtual disk [[iSCSI (ME2)] VM4_testrestore_delete/VM4_testrestore_delete.vmdk] because it is read-only. Please ensure that the proxy has write access to the disk. For SAN mode it may be necessary to use DiskPart to clear the Read-Only attribute.Source: mediaagent01

Windows Proxy with linux MA+VSA

Hello,Hypervisor is VMWare 6.7VMs are windows server 2019Media Agent is a linux one, with VSA installed. Full VM backup/restore are easily performed.But for granular restore (live browse) from the VSA backup of a VM, a Windows VM is required. It have difficulties to find documentation (or best practices) regarding the deployment/configuration of this VM. Simple questions, like which packages to deploy on it… Surely MediaAgent, but only this one?. A lot of documentation exists when the MediaAgent is running Windows and the VM is linux, as the FREL is available to download, or even how to install a MediaAgent over a linux VM and convert it to FREL. But when the OSes are reversed, I’m lost. Has anyone information to share (at least to me ) ?

Issue adding tags to virtual machines with vCenter Server 7.0 U2b

 IssueVMWare recently released update 7.0 U2b to address two high profile security vulnerabilities.If this update is installed it breaks VMWare tag associations, which in turn means that if Commvault backups and virtual machine reporting (specifically Chargeback) are based on VMWare Tags those backups or Reports will also no longer function properly.Security IssuesVMware vSphere Client (HTML5) contains a remote code execution vulnerability due to lack of input validation in the VMware vSAN health check plug-in. A malicious actor with network access to port 443 might exploit this issue to execute commands with unrestricted privileges on the underlying operating system that hosts vCenter Server.

Why SAN transport mode is only supported for proxies on physical computers ?

Hi,We are planning to change the setting of our current Commvault Server transport mode from Network to SAN based.However, when I check the manual, it says the SAN transport mode must a physical Server as the Proxy Server to back VMsThe fact is, we have been using Netbackup environments at somewhere else for years where the master / Media Servers doing VM backups are Virtual Machines but with HBA cards directly presented to them, so that all the datastores are visible to them. So, I’m just wondering why many backup software vendors (like Commvault) don’t support the configuration of using a Virtual Machine as the backup host for SAN (transport mode) backup VMs ? Thanks,Kelvin
