Linux proxy for Xenserver

Hi All,we have to backup a large number of VM on Xenserver.I created Windows proxy and added it as access node. i was able to backup windows & linux Vm with this.but when I went for Guest file level restore then it was asking for FREL enable ( for both Linux & Windows)Then i added another VM in same host with linux os and enabled it for FREL with media agent role and then Guest level restore worked for both.Now, I want to use only Linux VM as proxy and want to get rid of Windows at all, Can i do this?I do not see any option to add non-widows Proxy as access node in xen pseudo  client in commvault.Does it means , i will have to keep one windows VM as proxy for backup & one linux VM for FREL? it would be great wastage  of resources . please confirm and suggest any workaround.

VMware intellisnap netapp

Hello,To improve out RTO time we are thinking about following scenario:current we backup VM via VSA backup to MA, and AuxCopy then the data to a CIFS share which is sitting on a NetApp with SnapLock configured . In case of ransomware attack, we will restoration via VM restoration process from the CIFS share.In future we want restore in case of disaster direct the volume which host the VMsnow my question is possible to handle this during commvault completely?  VM backup configured with IntelliSnap take snapshot on volume, then it triggers a SnapVault to a NearStore only for full backups (SnapLock configured), after this it takes backup copy for standard backup, where we have longer retention and possibility to restore single VM or single files….In case of disaster, we can restore full backup volume via IntelliSnap restoration then we restore VM backups from the standard backup. This should be much faster as restore whole VM from VSA backups.Question is will this work, or is there a thin

Correct order of virtual VSA SCSI Controller IDs for hotadd usage ?

Good morning,according to the BOL arcticle below, it is crucial to check the order of SCSI ID numbers used for a virtual VSA in VMware.HotAdd Transport for VMware (commvault.com)The IDs used in my environment are different to the IDs in the BOL article.Can someone tell me whether it is posible, that I ran into the described situation ?The high number (1184) mentioned in the article is assigned to the ethernet controller, while SCSI Port Numbers seem to be in ascending order also digit-wise.we’re also facing sporadic file access errors as described in the arcticle, each time for different VMs BRKlaus

Issue connecting vCenter to Commvault

Hello, I have a fresh installation of Commvault version 11.28.56. I am attempting to connect to our vCenter instance through the Command Center GUI. After putting in the information to ‘Add Hypervisor’ I receive a ‘Request body is empty or format is invalid.’ error. Clicking equivalent API shows the following:{  "vcenterHostName": "172.16.123.10",  "name": "vCenter",  "accessNodes": [    {      "id": 2,      "name": "n1-prod-commvlt"    }  ],  "userName": "vsphere.local\\administrator",  "password": "cGFzc3dvcmQ=",  "hypervisorType": "VMware",  "skipCredentialValidation": false} Attached is the error. I have tried vsphere.local\administrator, administrator@vsphere.local, and a Windows AD account. I ensured the ‘VSA’ software was installed on the access node. Any help is appreciated!Error

VMware Backup on DRS enabeld Cluster is leaving orphanded files behind

Hi Team,we are running SAN Transport Backups agaings a Fully Automated ESXI Cluster. During the long running backup the DRS feature pops in and doing a Storage VMotion against VMs which are currently backed up. Eg VM on DS1 → is storage vmotioned to DS2 After the backup we still see all the “Orpahned Files” on DS1.  We tried to utilize the additonal Setting “bDisableVMotionDuringBackup” which did not prevent a Storage VMotion during the backup.  We are currently running 11.30.If i am not not wrong we saw in ealrier commvault Versions ( 11.28 ) a Taks in the VCenter → VM → Tasks like “DRS disabled” during the backup.  ( not sure but maybe with Transport mode “NBD” this issue is not seen ) Anyone facing the same issue.

HotAdd not working for VMs on other ESX host than Proxy

Hi,I’m currently experiencing issues with Hotadd backups using a VSA Proxy. The VMs running on the same ESX host as the Proxy are being backed up via Hotadd. However, VMs running on a different ESX host than the Proxy are being backed up via NBD.As described in the Documentation: “If the virtual machine and the proxy are not on the same host, all datastores must be shared between the hosts and the hosts must be within the same datacenter. “All datastores are shared between the hosts but they keep using NBD. I checked the logs and I can see Hotadd being disabled:6452  1724  06/24 07:27:12 XXX CVMWareInfo::AdjustTransportModeForBackup() - Disabling Hotadd for VM [XXX] on NFS storage hosted by [XXX].  Proxy is hosted by [XXX]What am I missing here?Any ideas are appreciated!

P2V SQL Cluster

Hello CommunityAfter restoring a physical SQL server that is apart of a always on cluster to a vmWare VM the mount points did not work.The disks were restored in an offline state and could be brought online manually.However when using powershell to list the disks of the server it only found 1 disk.So the question is whether or not it is possible to use P2V to restore a SQL cluster?

Azure Access Node Autoscaling

Hello,I have 2022E version of Commvault server in Azure installed. Then I created a Windows media agent and one Windows Access node (VSA agent). I created a Azure cloud library and a server plan. Then I created an IAM AD application (the traditional authentication way) in Azure and then a hypervisor client in Commvault. Then I followed instructions for autoscaling of the access nodes: https://documentation.commvault.com/2022e/essential/128139_auto_scaling_for_azure_access_nodes.htmlI would like to present this functionality to the customer before it will be transferred to production. The configuration seems to be OK, but all test backups are running via the 1st access node I created before. Unfortunately I have only 4 windows VM’s for testing. In the documentation the condittion for creation of next access nodes are:“The Commvault software determines the number of access nodes to create based on the following characteristics: The Recovery Point Objective (RPO) The throughput rate T

VMware backup selection methods for a single vCenter & Commserve manage two DCs apart

Hi Good Day!Environment:One commserve to manage the backup of 2 Data centers in different locations.One vCenter to manage VMs of 2 DCs. It is in the stretched cluster the VMs shall move between the DCs.Question:What is the best method for selecting the VMs discovered in the local DC for backup? Do not want to load the VM backup traffic across the DC in a failover scenario. Could select the backup based on VM presented on the ESXi hosts in the local DC? Or can I use tag, Folder & Data Store based VM selection? Which method best satisfies the requirement?

limiting streams not per datastore but array

Hi guys, I am struggling to find a balance between stream and datastore limits for our environment which has many datastores and clusters on a shared flash array (using SAN transport). The VSA client also contains numerous remote sites all backing over over NBD, all of which funnel to the same MA/access node. The MA has plenty of resources but is fast enough to really hammer the array.https://documentation.commvault.com/11.21/expert/31115_performance_tuning_for_backups.html is what I’m referencing but I see no clear cut way to throttle TOTAL datastore streams hitting the SAN but not limit all the various NBD-based remote subclients. Meaning - I can’t limit the streams of the MA without impacting the run times of all those NBD clients because they take hours to complete in some cases. Basically what I’m looking for is a way to have the proxy/access node tell “hey, all these subclients and datastores reside on the same array, so limit total streams for all those combined SAN streams to s

VMware VSA backups via SAN impact performance on underlying storage

Hello!Customer used to run VMware backup using Netbackup, via NBD. They moved to Commvault and SAN transport mode.Happens that, even with few data readers (6), underlying storage (SAS+SSD pool on a DELL Purity)  where the Datastores resides is suffering a lot. Overall latency goes so high that the production environment goes down. We are using HSX and SAN is 16Gb.Does anyone has any experience with situations like this? Any clue? Is HSX via SAN too much for their storage?Regards,Pedro

2 snapshots of the same vm during backup

We have some strange issues with vmware backup for one of our customer, from what i can understand it looks like commvault has told vmware to take 2 snapshots of the same vm with 30mins between them. we have then had issues with too many cvlt snapshots on the same servers and my initial guessing is that it’s due to what we see from the vmware side that the cvlt serviceaccount has taken 2 snapthots and only removed one after backup is ok. Has anyone here had the same issues before and fixed it?

VMware CBT and Full backups

Hello! I know CBT is a VMware functionality that Commvault and other backup softwares use. Netbackup leverages the advantages of CBT on both full and incre/diff jobs. Does the same apply to Commvault? Check this doc from NBU: https://www.veritas.com/content/support/en_US/doc/21902280-127283730-0/v27791754-127283730Backup of entire virtual machine, with full schedule: Backs up only the blocks that have changed since the .vmdk was created. Note that the blocks that are not initialized are excluded from the backup. Backup of entire virtual machine, with incremental schedule: Backs up only the blocks that have changed since the last backup, as follows: For cumulative incrementals, BLIB backs up only the blocks that changed since the last full backup. / For differential incrementals, BLIB backs up only the blocks that changed since the previous backup of any kind. So, will Commvault full backups also get the advantages of CBT?Regards,Pedro

Amazon MALZ integration with Commvault

Good day.Does anyone have experience with protection workloads in a AWS AMS/MALZ environment? Are all the features supported? I heard that some features relating to agentless protection and recovery operations will not be possible due to the restrictions placed on the making use of snapshots (VSA / RDS), creating VMs/DBs, assigning permissions to resources via IAM, etc.When using the agent in-guest approach this should not be an issue as I have it.The idea is to integrate this environment into an existing on-premise Commvault deployment. I do see that there is an option to create a “Customer Managed” OU within the MALZ environment but this would still make use of some components within the Core OU managed by AWS.Any information will be appreciated.Regards,Ignes

Azure Replication / Sync failed

Hi! We are trying to replicate an Azure VM to a storage account located in a different region. Backup of the virtual machine worked, but when trying to use the “Replicate now" prompt, replication fails due to a sync error. Further investigation into the replication group/VM showed the error “One of the disks exceeds the maximum allowed size for an Azure VHD page blob". Is there a way to work around this? Specially that we are planning to replicate even larger capacity VMs. Any help is greatly appreciated

Virtualize Windows Server

Hello,I have a query to the community. A customer is asking me to create full backups of his virtual machine, so that later, in case of error, I can perform a restore of his full virtual machine in my vCenter. To be able to perform the full backup of his virtual machine, I must create a VMware vCenter Commvault agent of his environment in my commserve, and then in the subclient, add the virtual machine he wants, no? Is there any other possibility? We currently have a Commvault agent of that virtual machine but we are only doing the 'File System' backup.Thank you all very much,Best regards😊
