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

Backup and Restore very slow in Oracle Cloud Infraestructure

Hi Commvault community! Does anyone know if commvault has any paper for the case below?Does CommVault have implementation best practices documentation for backing up VMs on Oracle Cloud Infrastructure?Backup/restore performance involving Oracle Cloud Infrastructure is very slow. In the backup configurations of Oracle Cloud Infrastructure, there are no features like there are in VMware so that we can adjust and improve performance.Is there anything we can do on the CommVault side to improve performance?In VMware, we tested restores with a throughput of > 200GB/h. Oracle Cloud Infrastructure's throughput is always less than 40GB/h using the same servers.This makes an OCI native VM of only 50GB take more than 1 hour to restore. We don't have bottlenecks between Oracle Cloud Infrastructure and CommVault because the entire Commvault architecture is built inside Oracle Cloud.Does anyone have similar infrastructure with backups and OCI? Thanks,Heitor

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.

VMware Cloud Director 10.5 support

Hello, Has anyone heard anything from Commvault regarding support of vCloud director 10.5?It was released sometime a month ago i guess and customers are already starting to push us for the upgrade.With the 10.4 release in mind and the deprecated API’s for backup in that release I googled and I see that on the green competitor’s forum that if you do the upgrade to 10.5 now, backup will just stop as it did when 10.4 was not supported by Commvault or other backup providers.

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
