When Backup runs from Veeam B&R I get this event id 157

Disk 1 has been surprise removed.

This happens on all servers I listed above.  

Would like to know if I can suppress this event

I applied KB2955164  no change

I ran diskpart automount disable    and diskpart automount scrub     no change

Has anyone figured this one out?



I added a large 3TB VM to the Veeam backup job and ran it over the weekend. It started out processing fairly quickly but gradually got slower.  I looked at the esxi console and there was the question about the redo log file being corrupt.  CAlled Veeam support who suggested that to stop the job and manually consolidate the disks, but I cant do that - the option is grayed out.  

I havent clicked on the OK button to the above question as I fear the VM will boot.

Any advice?
Dear Experts, we are using Veeam B&R 8.0 to backup VMs to a NAS. But the storage's size was consumed very fast. Please see the attached pictures for the settings of restore points and VM retention in Veeam.

In the rest picture, you can see we have some .vib (incremental) and .vbk (full) backup files. Questions are:

1. If we setup the restore points to 15, why did not Veeam delete backup files before October 1st automatically? Is there any setting which we can config to achieve that?

2. Can we delete some backup files manually?

Many thanks in advance!
We have one particular Windows server (an AD sync server that relates to Office 365) that has been failing for days. Three other servers in the same backup group is fine, and can back up with no problem. I removed open snapshots on this particular server but still to no avail. Attached is a screenshot of the error I continue to get. Please advise on what I can do to resolve this issue. There is more than enough space on the C: and storage provided to the VM.

Dear Experts

I plan first to clone the VM from Hyper-v to ESXi 6.0 (via VMware converter - cold migration) to new HW and then I need to increase the VM's C-drive disk space. Best methods to do that?
My Veeam backup server failed.
Would like to reinstall and make it up.
Appreciate if someone can guide how to recover a failed Veam server.
Backup files are safe in NAS.

Now we r running without a backup solution.
An error was received from the ESX host while powering on VM VEEAM.
Failed to start the virtual machine.
Module Disk power on failed.
Cannot open the disk '/vmfs/volumes/56f421ed-263be15c-c931-e435c87f06f4/VEEAM/VEEAM-000001.vmdk' or one of the snapshot disks it depends on.

I deleted some LUNs to recreate a better LUN. Veeam was not installed in SAN it was on local datastore.
I didnt delete the database or VMDK still I cant start the VM.

Server name is VEEAM.
If anyone can guide me how to fix this and boot would be great.
Looking at changing my current backup regimes, at the moment I have two sites that have two separate backup solutions.

Site 1.  All VMware Servers which get backed up to Dell SAN Storage via VEEAM which then gets replicated off-site to another Dell SAN which sits in a Data Centre and has a site to site leased line.

Site 2.  Mix of VMware Servers and Physical Servers which all get backed up to HP via MPLS and then to HP

What I would like to do is set a new backup solution that will backup to onsite SAN then replicate to the cloud for both sites.

I know this is a wide subject but my only stipulation is that I can backup virtual and physical servers using the same software and cloud storage platform.

Hi Expert, not really into veeam, but would like to know if veeam can perform this

i want to keep an incremental copy every day , then every week will consolidate to 1 set, follow by 4 weeks, consolidate to 1 month copy full copy (for a month) , and i wish to keep a full backup image for every month, and able to keep for 7 years.

possible to do that with veeam? as im pretty sure storagecraft manage to do it.

I had a corrupted VM so I just did a restore and now it is working perfectly.
BUT... I cannot backup it anymore.

Is anyone here using AutoDesk Vault and if so, how are you backing up your Vault instance(s)? I am told that AutoDesk only recommends a particular backup solution (Symantec I think) but we're getting ready to move the Vault instance over from a standalone physical box to a VM. I would really prefer (after the migration) to back it up using Veeam along with all our other VMs in our vCenter. However, because Vault uses a SQL backend, I have been told that I may want to also do something specifically with the individual SQL databases in addition to our normal backup ... and that this may very well be the reason why AutoDesk recommends a specific backup solution for it. So I need to know how others are doing it.

In addition, we would love to be able to share certain files stored in our AutoDesk Vault with a partner or two and we are not quite sure how to even approach that, so if anyone on here has any experience in using the AutoDesk Vault product and sharing Vault files from it, it would also be great to hear how you guys do it.
VM Snapshot when Datastore is low in Space

I have a Virtual Machine VM1 of 300 GB disk size, the Datastore1 it is located on has 100 GB Free space.

However the Datastore1 is in a Storage ClusterA, I mean under Datastore ClusterA, there are several Datastores , with plenty oof space,  besides Datastore1

I wonder if the Snapshot of VM1 will work even if Datastore1 has lower space (100GB) than the disk of VM1 (300GB)

*** The snapshot is initiated by Veeam Backup Software, I see:
Error: The operation is not allowed in the current state.  

Thank you
Hello Expert Exchange community,

We have one backup server that is running 2 backup applications - BackupExec 16 (to backup our physical servers) and Veeam (to backup our VMs).  The server is connected to a HP StorageWork MSL2024 with 2 drives. Is there a way to dedicated one drive to Backup Exec application and the other drive to Veeam without any conflicts?
How can we setup a temporary VEEAM server for a customer that will be moving to a new IT firm and datacenter in a couple of months?
Normally we'd setup a site-to-site VPN install a vCenter appliance at the client datacenter and a VEEAM console on a Windows VM, and we'd rent out VMWare vCan license and VEEAM to use in the client datacenter.  
In this case the customer is moving to a new IT firm and datacenter shortly and the new IT firm already has full access.  So we can't let the new guys in the other firm get hold of the rental licenses.  
Is there a feasible option for running the VEEAM and vCenter appliance on our end, and some kind of proxy at the client datacenter?  The backups are to be stored at a locally attached storage device at the clients, maybe with a replica in our datacenter as a bonus.

Backup was running fine for a couple of months until recently. Error: VSSControl: Failed to freeze quest over network, wait timeout.

Restarted server, repaired SQLVSS Writer, increased timeout as recommended by Veeam, changed service to domain administrator, VsPhere able to take snap and another backup software able to do application aware backup.
Hi Expert

we have around 20 of ESXI servers with around 400 VMs

we need to buy VEEAM

my question

we are going to backup to disk let us say to NFS or CIFS and we need also to backup to tapes

but what type of tape library we have to buy if we don't want to use fiber

can we backup from our ESXI server using  VEEAM to tape without any other server to work as storage node or something like this

can we avoid using fiber interface and fiber switches

kindly advice
I recently updated Veeam Backup and Replication from 9.0 update 2 to 9.5 update 2. Since completing the update my nightly backups have started having multiple backup failures on random guest OS running Windows. I run VMware ESXi 5.5 backing up to HP StoreOnce using CIFS. There were absolutely no VSS errors prior to the upgrade to Veeam 9.5. The guest systems having issues are a mix of Windows server 2008 R2 and 2012 R2 and Windows clients 7 and 8.1. There are three different backup jobs, each has guests experiencing the issue. I also have two 2003 servers that have not experienced the issue.

I have contacted Veeam support and provided event logs from a few target systems and Veeam Backup and Replication. They have told me to contact Microsoft stating it is a VSS issue and not Veeam. Microsoft will only test one guest per incident for this which does not help resolve the issue.

I am curious if anyone else running Veeam Backup and Replication has upgraded to 9.5 and experienced these issues, if so have you been able to resolve the problem?

Also important to note, for the backups that fail on first run, some succeed on first retry, those that fail on first retry succeed on second retry. I have not had any systems that have not had a successful backup after 3 attempts, this tells me Windows systems are ok otherwise I would expect the backup to fail every time.

On Windows machines that experience the error the following event log entry is found:

I am using Veeam Backup and Replication to perform some backups of some linux based VMS. Recently, I started getting this error below:

Getting VM info from vSphere
Error: DiskLib error: [16].No file exists for given path -- File open failed: Could not find the file --tr:Failed to start file downloading.

so far I have deleted the VMs from the backup job and readded them, created new backup jobs, but I still get the same error message
The is using Veeam agent for Windows. The setup and configuration is straightforward, and the backup works perfectly. However, found that the retention policy doesn't work. Please see the configuration as attached. I use the default 14 days for retention. Besides this, the Active full backup is enabled too. However, the end result is, backup images of older than 14 days are still there. What's went wrong, and how to get this retention works?

Thanks in advance.
I backed up a 500GB HD with the latest VEEAM Free for Windows.
Then I tried to restore to a 1TB hard drive and it came back that "Auto......." was unsuccessful .. something like that.
I think this strange and would have like to avoid it.

Next, I manually restored the C: partition and the likely other partition of size ~450MB.  I left out the 18GB (recovery partition?) and one other very small partition.  It wouldn't boot from this....
It would be nice to know how to select so the drive will boot.

(same computer...)

I have 2 Physical Servers.
1 is having my VMs (5) and the other one is having REplica's of those VMs using Veeam.

The replicas are getting big (coz I increased the VMs sizes of their HDDs. and I am running out of space In the Replica Folder (D:\) of the second Physical server.
My question is the following
Can I delete those replicas and re-create them on my NAS ? (I have a QNAP that has enough space). or the replicas can only be on the Fixed disk of the Server (second Server that has Hyper-v Installed ?
Is it "dangerous" to delete the replicas ? How do I delete them ? just delete ?

Thanks for pointing me to the right direction
Env. Windows 2012 R2 / Hyper-V / Veeam Backup & Replication V9.2

Thanks again
Dear Experts, we realized that Veeam 8.0 displayed the incorrect information about our VMs. These 2 hosts have nothing in used size for sure (they were thin-provision and took about 500 GB each). This leads to the slow backup time (even it is just incremental). I also got the proxy bottleneck. I also got the notification from Veeam that these 2 hosts were no longer processed by this job?

Do you know why and how to fix this?

- Veeam 8.0 R&R
- Win server 2012R2
- VMware ESXi 6.5

My Exchange Server 2013 DAG mailbox (Passive) cannot truncate the transaction logs with the below error as I can see from the backup software (Veeam):

As at the moment, there is no Active mailbox DB running in PRODMBX01-VM so it only holds a passive copy.

Any help would be greatly appreciated.
