Restored vhdx (Hypver-V) unable to mount
Hi all, I'm working for a small charity that has three WIndows Server 2019 hyper-v servers running a couple of VM's. I have forever incremental backup jobs running that seem to be running fine. However, after a successful restore, I've discovered that some, but not all, of the restored vhdx files have no partitions or no drive letters assigned when mounted. When right clicking on a restored vhdx file, one of three things happens depending on the vmdx. It mounts fine and assigns drive letters - that's the normal behavior that I'd expect. That does happen with many of the restored files, but not all unfortunately or Frequently I will get this error message Couldn't Mount File The disk image isn't initialized, contains partitions that aren't recognizable, or contains volumes that haven't been assigned drive letters. Please use the Disk Management snap-in to make sure that the disk, partitions, and volumes are in a usable state. then one of 2 things happens. Either 2a. In disk manager, I am asked to initialize the drive. After doing so there are no partitions on the drive, making it unusable. or 2bSometimes I can se the partition(s) on a virtual drive in disk manager, but there's just no drive letter assigned. I still get the above "Couldn't mount file" message, but I don't need to initialize the drive, it just shows up in disk manager with no drive letters. This is pretty infrequent, it's usually 2a when I have a problem VHDX. When I can see the partitions, I can assign a drive letter, but I'm not sure what would happen if that VHDX file were used as a restoration that was to be spun up in Hyper-v Has anyone seen this before? I've not on any of the other servers I manage elsewhere with a very similar configuration. I should add that for each vm, all restored vhdx files for that vm will either all be okay, all have no partitions, or all have partitions but with no drive letters. I did create a NEW forever incremental backup for each of the 3 servers. I ran a new backup on one to test, then did a restore. 3 vm's restored fine where I could open the vhdx file, 3 gave me problem 2a above, and one gave me problem 2b. Any suggestions as to why this is happening and/or what I might be able to to stop it? No point in backing things up if the restores are unusable!! Thank you all
nbhypervtool.exe
Dear Veritas Enthusiasts, i would like to ask if anybody has additional information about thenbhypervtool.exe. i need to know whatnbhypervtool.exe does in the back, does it only delete the snapshot, is it the same as using the powershell cmdlet remove-vmsnapshot or there is slightly different functionality. i am asking for these details in the context of some left snapshots of hyper-v virtual machines and the possible supported steps to remove old snapshots that netbackup left after the backup. thank you in advance!hyper-v backups are failing with status code 13 or 25 if the hyper-v virtual machines has a snapshot
any ideas are welcome on the following as the case we have with veritas is almost 2 months old without any progress: if the hyper-v virtual machine has a snapshot which was created from hyper-v or failover console, the backup of the vm fails with status code 13 or 25: 28.09.202018:57:27-Errorbpbrm(pid=145214)socketreadfailed:errno=104-Connectionresetbypeer 28.09.202018:57:27-Errorbptm(pid=147427)systemcallfailed-Connectionresetbypeer(at../child.c.1289) 28.09.202018:57:27-Errorbptm(pid=147427)unabletoperformreadfromclientsocket,connectionmayhavebeenbroken 28.09.202018:57:28-Errorbptm(pid=147293)mediamanagerterminatedbyparentprocess 28.09.202018:57:33-Infoxxxxx(pid=147293)StorageServer=PureDisk:xxxxxx;Report=PDDOStats(multi-threadedstreamused)for(xxxxx):scanned:3KB,CRsent:0KB,CRsentoverFC:0KB,dedup:100.0%,cachedisabled 28.09.202018:57:35-Errorbpbrm(pid=145214)couldnotsendserverstatusmessagetoclient 28.09.202018:57:37-Criticalbpbrm(pid=145214)unexpectedterminationofclientxxxxxx 28.09.202018:57:38-Infobpbkar(pid=0)done.status:13:filereadfailed 28.09.202019:00:15-connecting 28.09.202019:00:16-connected;connecttime:0:00:00 28.09.202019:00:22-beginwriting 28.09.202019:00:35-endwriting;writetime:0:00:13 filereadfailed (13) a workaround is to disable exclude deleted block and swap and paging files but this is not appropriate for us due to negative performance impact thank you all!
Choosing backup source for VMs on Hyper-V: Cluster or Node?
Greetings, all! Our site has a new 2-node Hyper-V cluster that will replace our well-aged VMware ESXi 5.5 cluster. So, I'll be using Backup Exec (v.20.5) on Hyper-V for the first time as we build new servers on and move existing servers (?) to the new system. Having pushed the Agent for Windows successfully to the two nodes, I noticed that the cluster appeared in the list as well and can be backed up along with its VMs. The VMs can be backed up by choosing the nodes, too, which makes me ask which method is the better one. I don't recall seeing a mention of the two possibilities or a recommendation in the Administrator's Guide. What can those of you with experience in such a situation recommend as a backup strategy? Thank you for sharing your collective wisdom!
Protecting Hyper-V Virtual Machines on SMB using Backup Exec 20.4
Starting from Windows Server 2012, virtual machines in Hyper-V can be configured to use Server Message Block (SMB) 3.0 file shares as storage just like local volumes. By using SMB shares, storages for Hyper-V can be converged and operating costs can be reduced. Additional advantages of Scale-out file servers include continuously available file services, automatic load balancing and easy management of servers. Deploying Hyper-V over SMB shares from Scale-out file servers is an ideal solution for Hyper-V.need help to configures hyper-v server backups
A little background infomation: I am in the process of upgrading our BackUp Exec server and backups. We were on version 2012. We are upgrading to BackUp Exec 16. I built a new Windows Server, OS 2012r2 and installed the Backup Exec 16 software without an issues. I have a few physical servers that aren't VM host. I comfigure them. All are backing up without issue. As for the VM Host and virtial machines, I'm wanting to use the new features so I can use file/folder-level Granular Recovery Technology (GRT). I'm just not sure how ro back up the VM's so I can do this and use Simple Disadter Recovery too. In otherwords, I want to be able to recover the whole VM and/or a file from that VM. What is the correct way to do this? As so, when I configure the backup, when do I need to capture the Host Components? I have included a screenshot of what I'm trying to do. Just not sure if I need to have 2 backups, one for SDR and one for GRT. Any advice or instruction on this matter would be greatly appreciated. Regards, ABBEadmin
V-79-40960-38528 received when backing up Ubuntu 16.04 Server guest on Hyper-V 2016 host
Hello- I am running a Server 2016 Hyper-V host. On the host I have multiple Windows and Linux VMs running as guests. The Linux VMs are Ubuntu 16.04 Server-based. To simplify administration, I back up the Windows VMs in one backup job and the Linux VMs in a second, separate backup job. I am receiving the following in the job log for the Linux VMs: V-79-40960-38528 - The Hyper-V subsystem has reported that the Hyper-V Integration Services (HIS) inside the virtual machine do not match the version expected by the Hyper-V host. An offline backup of this virtual machine has been performed, update the Hyper-V Integration Services to ensure online backups can be performed whenever possible. I have de-selected all GRT-related options for the job under Backup Options-->Virtual Machines-->Virtual Machine Granular Restore Technology Settings. I have Instant GRT enabled under Backup Options-->Instant GRT (the default). Also, I have installed and upgraded both linux-tools and linux-cloud-tools packages in the VMs. I still receive the error. Any help would be appreciated.
