Windows Cluster Backups Creating Non __GX_Backup Checkpoints and not removing them

I’ve had this problem for years with 2012, 2016, 2019 and now Azure Stack HCI clusters where, if there’s been some sort of blip on the network or with a particular host, that we can get increasing numbers of non __GX_Backup named (normal named) .avhdx files at every backup on a small percentage of VMs (not the same VMs each time and problem is intermittent).The disks show as differencing but there are no checkpoints listed on Hyper-V manager and this usually requires downtime to consolidate the disks by restore to fix it.Commvault support advised they’ve never seen this particular issue before and that have always said that it’s a Microsoft issue but I wondered if anyone else had ever seen it.I don’t have the issue with non clustered VMs where the backup type is set to “File System and Application Consistent” instead of “Crash Consistent” like it is on the clusters.I think the issue is probably more related to the clusters than the backup type but am not sure. If I do change the backu

Mount Points not being backed

Hello, I am trying to investigate an issue going on in our environment where a stakeholder is asking us to audit our environment and what is being backed up. I am starting to look into their servers and notice on a couple of servers in the most recent full and see several mount points are listed but some of the mount points show no data, this is what I was suspecting. However, some of the mount points are showing data and it appears that it was able to backup the data in this mount point. Looking into why Commvault was able to backup some mount points but not others? Does it matter what type of protocol the storage array is using - CIFS or NFS to be able to be backed up? Thanks for any info or documentation you can provideCody

SOLVED - Misleading Error: "Live Mount is supported by VMware VMs only".

Hello, everyone!This post is mostly intended to provide a search result in the event someone comes across the same issue I did. If this type of post is not allowed please forgive me. While trying to perform a Live Mount for a VMware VM being backed up via a connected vCenter environment, the job was failing with error description “Live Mount is supported by VMware VMs only.” Naturally I was confused because the backed up VM was in-fact a VMware VM. Googling yielded no results, hence this post. The cause was rather simple: the job was just failing because an existing backup job was still running. Even though the VM itself was already finished being backed up, the parent job was still running on another VM. The solution was to just wait for the entire backup job to complete. I hope this helps keep someone from panicking in the future!

Virtual vs Hardware Agent

I have a Windows server configured as a VM running on VMware, this server has a LUN attached with iSCSI with a file system that is NOT a virtual disk. Am I correct in saying to back this up I need to use a Full Agent such as a Hardware agent? Currently as configured the only backups I am seeing are the Virtual disks associated with this server such as the startup disk.

VSA Transport Mode on VMware over Nutanix Virtualization Environment

Hi everyone.We are facing a Commvault Backup implementation of a VMware Environment over Nutanix Cluster. Our initial idea is to perform NAS Transport Mode or HotAdd mode so as to avoid NBD and get more backup performance.On Commvault side we see that it’s fully soported (we treat this kind of Backup as it was a regular VMware deployment at Commvault level).The thing is that we have found on a Nutanix Document (attached) that it’s a Best Practice to implement NBD backups once protecting VMware VMs with Streaming mode, as you can see in the capture below: We suppose “that performance issues” refer to too much I/O on Distrubuted DataStore of NTX environment. We have checkd on other environments that HotADD mode works and “apparently” no impact has been seen. Does anyone has faced a similar scenario? and in that case, was NBD implemented? Regards and thanks for your help!

Need to Improve backup and restore speed

Hi,Below is my configuration:Commserve is VM machine and version is 11.24.103.Media servers - 1 is Physical and another is VM - Both are configured as Disk’s library (Disk’s are coming from Storage Lun’s).Proxy Node (Access Node) - Both media servers are assigned as access node.We have around 100 VM servers under a vCenter, so I have split 10 sub clients in each VM.I have selected the Auto mode and backups are running nbd most jobs.Currently, I can see the backup/restores are running very slow. Is there anything I can do improve the speed. Thanks in advance.

hotadd port requirments in vmware

Hi,i have a question about the implementation of some VSA proxy in hotadd mode only on vmware VSAN.it is really needed to open network port 902 between VSA proxy and ESX host ? can we only open port 902 between Vcenter / media agent /vsa ?in my undestanding the port 902 is only use in NBD/NBDSSL mode as a fallback mode when other transport mode are not available.regards,Christophe

Commvault and Google Cloud VMware Engine

Hello everyone, I looked in the documentation, however, I did not find anything about it. How can I perform DR of on-premise VMware VMs using Google Cloud VMware Engine as target? Are there any restrictions or best practices for implementation? Thanks, 🙂Antonio.

Issues with sporadic failed VM Backups via hotadd

Hi,We’re running into a strange issue with hotadd VM backups.For some VMs we see the error “Failed to download config file” and “Failed to open disk”. This is never for the same VMs over and over again, but sporadic and always for different VMs.We have two SCSI controllers defined on the Proxy and each controller has a “dummy”/”actual” disk as the first disk. (As advised by VMWare: https://kb.vmware.com/s/article/2075069Has anyone ever seen this issue? Any idea what might be causing it?

Max number of Simultaneously Mouted HotAdd Disks PVSCSI on VSA Proxies

Hi everyone,We are currently deploying a Commvault environment to protect via VSA a great amount of VMs (almost 6000VMs)VSA proxies are Windows Server 2019 SE VMs that reside on the same cluster that VMs we would like to protect. So transport mode will be HOTADD.We are currently on test phase so as to obtain results and determine the number of VSAs Proxies that finally we will deploy.The environment is the following: Commvault version: v11.24.7 VCSA: VCenter 7.0u2 ESXi Version: 7.0uw VSA Proxies O.S: Windows Server 2019 SE VDDK version used on Backups: 7.0.1As per VMWare documentation says on VMWare 7.0u2 each PVSCSI card on the proxy VSA should be able to mount 64 vmdks of the Backed-up VMs.The issueis that we are monitoring during the backup and each proxy is just able to mount 15 disks via hotadd (stucked on the previous limitation of VSphere 6.5)We have added manually more than 20VMDK disk on the Virtual Machine so we understand that this is not a VMware issue. The limitation arise

Intellisnap backup of an AWS EC2 instance that can perform a Pre and Post job script on the EC2 instance that is being backed up

We would like to run a pre-backup script that freezes our IRIS database on a Red Hat EC2 instance, after the freeze is successful we would want to run an Intellisnap backup of that Red Hat EC2 instance and then once the backup completes, unfreeze the IRIS database. What is the best way to get Commvault to orchestrate this process ? Thanks

Vmware VSAN Fault Domain support not working properly

Hi Guys,we’re running on Commvault 11.28.69Backup of VMs on a streched VSAN Cluster, where VSAs are deployed to both fault domains, enabling the use of hotadd transport mode in both locations.The backups are currently assigned to any available VSA, without honoring the fault domain. This creates additional WAN Traffic and also has an impact on backup performance.According to BOL this feature is available since 11.20New Features for Virtualization in 11.20 (commvault.com)I also defined bEnableClusterFaultDomainDispatch = true (should be default) on all VSA, but doesn’t lead to a proper VSA selection. Once the VM is not running on the same host as a VSA, any VSA is assigned.Are there any further settings to enable (or the other way arround to disabled) that lead to a propper asignment of VMs to VSA ?As a workaround, I now assigned the usable/wanted VSA now to each virtualization client’s subclient instead of the instance only. This restricts the VSA to the local fault domain only, but th

Live Sync: Prioritize replication of full backups

We currently have Virtual Machines replicating with Live Sync, Full is executed and then incremental, my question is, is there a way to prioritize that the Full backups are copied first and then the incremental ones, we see that it does not replicate the full VMs first, if not It seems that it prioritizes smaller VMs.
