Azure Site Recovery / Zerto or Veeam?


Im investigating and testing replication of a test VM we have in azure and failing miserably.  Current production config:
  • Site to Site VPN from our on premise site(s) connected into UK South Azure region.  
  • address space.
  • All production resources (Domain controllers only so far) located here.
  • A test SQL server VM stored here and being replicated by ASR to UK West region.
  • dedicated ASR vnet used at the UKWest site.
  • A dedicated failover vnet also used for the failover replica.

I clearly must be missing something.  I have yet to failover, but understand that the replica VM can have the same IP address as before but its recommended that it doesn't (depending on the address space and subnet?

Also am i right in saying we must either add vnet peering between UK South and UK West?  A VPN connected to UK West should UK South go offline or just allow external WAN IP access?

There doesn't seem to be much simple standard information for ASR.  I was hoping this would be easy and simple.  Which leads me onto Zerto and Veeam (currently using), is anyone using this in an azure to azure setup?  If so any pointers over ASR?

Dear Experts
We are having head office and site office both are connected over MPLS VPN, it is very much essential for us to have video record the activities that happens at the remote site hence we must install CCTV system to monitor and record all the activities, the following is what I am planning
Setup local server install VMware ESXi and on VM install the backup software point the as destination storage device where all the recordings are stored and configure backup software to schedule the backup for every 30 mins , the moment the backup session is completed replicate the same to remote storage which is in head office
1.      please help me with best practice design , can I plan for above design or suggest the best practice.

As there will be continuous recordings 24/7 hence too much of data is stored locally and also gets replicated to remote site , please suggest  the best practice should I have to plan like

2.      Please help on the following approach which one to go for or any other suggestion
At the site backup destination as disk and at remote site replication source also disk
At the site backup destination as disk and remote site where the replication happens is tape
At the site backup destination as tape and remote where the replication happens also tape.

3.      Is it good idea to have one more recording where real time monitoring and backup of site office happens from head office as we are connected over MPLS vpn network.
Please help on above 1 , 2 and 3
I need to confirgure a veeam job to backup a complete lun. Please can anybody give me the configuration?

Thanks in advance.

i created a backup job using a domain account. Once I disabled that account the job failed and gave me the following error
"Error : Unable to allocate processing resources. Error: All backup proxies are offline or outdated"

My question is how to make this job working even when I disable that domain account.

Any ideas?

Dear Experts,

My customer using Veeam Backup & Replication 9.5 U4.

We amended the host file of the Veeam server to point the IP address to each servers FQDN

The mistake happened when I created the backup jobs using the FQDN but the ip address was the production IP.

I have guided my customer to remove the backup agent but when he tried to run the backup job, he gets the following error:

Error: managed session 036b4aa3-e42a-46aa-b847-7367588c123f has failed
Hi Experts

I have a physical server running on Centos 7  and I have Nagios installed and configured on his host

Because we are using Veeam for backup and restore plus we have license for agents for physical servers

I configure the agent on this physical server and I managed to back up the host successfully

When I tried to restore a single file via Veeam console

As all you know Veeam uses a special appliance (( FLR )) to restore a single file

But I got an error

I open case with Veeam they told me no new info which I know before I open the case this is Veam answer

(( All 3 attempts to restore this file was unsuccessful, because Veeam B&R server was not able to connect to the Datamover that was deployed on the Nagios server the Datamover was deployed and started successfully:
So, I'll suggest checking the networking configuration between hosts (Veeam B&R) and (Nagios). It could be, that the port 2500 is closed, or, for instance, opened to establish connection from Linux machine, but closed for the Veeam B&R. If it is possible, as an isolation test, it would be great if you could lift all network restrictions between those hosts and try to restore this file after that ))
but I have no network restriction at all between Veeam server and Nagios server plus I disabled the firewall on Nagios and Veeam server also
please if you can give me n advice how can troubleshooting such issue step by step because Veeam support provides…
Dear experts,

Currently we are using Dell Tape library for backup the data of my company. I would like to ask which is the best technology for backup now a days. Cloud or Tape Library. (Less expensive and Easy to handle and maintain). We generate almost  5TB data per year. Can you suggest me please should I keep the existing one, or go for the cloud like Veeam?

Many Thanks in advanced.


I have purchased a Qnap server QNAP TS-1283XU-RP-E2124-8G 12 Bay Rackmount NAS with 96TB (12 x 8TB Seagate EXOS enterprise class SATA HDD 7200RPM)

I would like to use this for onsite backup, for backing up our Virtual servers using Veeam backup and backing up user files using BackupAssist software with  this Qnap server as a backup target.
In my situation, Is it best to use this Qnap as a NAS for backup Or do I need to set up the qnap with ISCSI target.

Please suggest , the best way of setting up this  and  help much appreciated.

I am setting up Veeam.

I have configured a weekly Forward Incremental backup job with synthetic full backup on Thursday. The backup repository is a Synology NAS.

I would like to know if I must select the synthetic full backup or active full backup option in my case as the NAS does not support ReFs ?

What happens if I select both synthetic full backup and active full backup in parallel at the same time ?
I have a client with a 2016 Hyper-V Host running only two guests.  We are backing the server up with Veeam.

Just after a reboot of the host, the backups will run successfully for a few days, then start failing consistently.

The two errors that show up in the logs are:

Hyper-V Server 3280
'server' could not initiate a checkpoint operation: The process cannot access the file because it is being used by another process. (0x80070020). (Virtual machine ID 22148F7D-625F-4EBD-BB60-2057CE7E7918)

Hyper-V-VMMS 18014

Checkpoint operation for 'server' was cancelled. (Virtual machine ID 22148F7D-625F-4EBD-BB60-2057CE7E7918)

Most of the articles I have found so far refer to cluster environments.

Note that application aware checkpoints are configured.
Dear Experts, our Exchange 2016 server's Transport service was stuck and hung at Starting status. We changed the logon account from Network service to Local system but it did not help. Our resource (HDD, RAM) were still normal at that time.

After rename the old queue in TransportRoles data and create a new one, that service could run normally again.

We'd like to know the root cause of problem and how to prevent it to happen in the future. Can you please advise?

Many thanks!

Another question is: in case we use Veeam to restore the queue file, will it be okay to use Sunday backup version?

Have VM Machine on Esxi 5.1.
Issue is the backups with veaam do not work after 41%.
it comes up with error stating next block transmission cannot be retrieved.
any suggestions in regards to this please.

Looking for some inspiration around DR/BC for our proposed migration to Azure.
Currently have on-premise tin.  Two sites where these reside - one production site and another DR/BC (test/dev) using DFS and veeam to replicate some (not all) data.  Its a true separate standby site.

I foresee a few options:

1.  migrate both to Azure and decommission the DR site.
2.  migrate DR site to azure as PoC site and replicate production here (may add complexity and cost).

What would you guys do here?

Dear All

            Is there any way to reduce vm storage size from Veeam backup ? i found that i can do it by using vmware convertor to modify the HD size, but in veeam is it possible to do that ? and i was trying reduce linux red hat size, any help would be appreicated

We are using Veeam Backup agent on a Windows Server 2016 device and we have been getting the following error.

"Error: Failed to create snapshot: Backup job failed. Cannot create a shadow copy of the volumes containing writer's data. A VSS critical writer has failed. Writer name: [SqlServerWriter]. Class ID: [{a65faa63-5ea8-4ebc-9dbd-a0c4db26912a}]. Instance ID: [{a03bc323-3b6f-461e-8101-7a5c41c37db6}]. Writer's state: [VSS_WS_FAILED_AT_FREEZE]. Error code: [0x800423f2]."

We get a similar error with windows backup and our cloud backup.

Veeam support have said its an issue with Windows.

Has anyone seen this before or had similar issues with VSS writers on servers?

Any help would be appreciated

as a reasonably inexperienced person with VMware, I have an issue with a VM. It is an SBS2011 server in production and the last few days there is an error in the event logs about the hard disk having a bad block. Since then our Veeam backups have failed with a CRC error. CHKDSK with no parameters (i.e. no attempt to fix anything) shows 8k in bad blocks.

I know chkdsk can be destructive to data, my worry is if I run it there is a very small possibility the VM will not boot afterwards - unlikely but that would be just me luck. To minimise downtime I was wondering if I could protect against this by taking a snapshot beforehand. If the VM gets broken by the chkdsk I could just revert to snapshot, would that be correct?

Thanks a lot.

I use to backup my Windows 2016 HyperV HV Server (2 VMs) with Veeam Backup and Replication on a Synology NAS repository

COnfig 1:
Windows Server 2016 HV:
- VM1:
- VM2:
NAS Synology

COnfig 2:
Windows Server 2016 HV: NIC1:, NIC2:
- VM1:
- VM2:
NAS SYnology:

COnfig 3:
Windows Server 2016 HV:
- VM1:
- VM2:
NAS Synology:

My concern is about security of data on the NAS which stores my backups (in the event of a CryptoLocker attack in particular)

- Which configuration is recommended for best practice?
- Is Config1 really unsecure and not recommended?
- Should config 3 works OK? The HV will have Internet access ? How?

Thank you for your comments and recommendations

I am in the process of setting up my Veeam Backup & Replication backup job for my VMware environment.  I was thinking that it would be best to backup the entire cluster so that all VMs, including those created at a future date, would be backed up.  The issue that I have is that my vCenter Server Appliance (VCSA) is also within that cluster.  

According to Veeam knowledge base article kb2328, I should enable VMware Tools Quiescence and that the Application-Aware Processing and Guest File System Indexing setting is either disabled or excluded for the VCSA VM.  After reading some further information of the Veeam site, it seems that if I enale both VM Quiescence and Application-Aware processing at the job level then Veeam will first attempt to use application-aware processing.  If Veem is able to quesce all the VMs int eh job with application-aware processing then it will not use VMware Tools quiescence.  However, if some VMs cannot be quiesced with application-aware processing, or application-aware processing is disabled for some VMs in the job, the Veeam will use VMware Tools quiescence to prepare the VMs for backup.  

Due to the fact that I have a bunch of Windows VMs, including SQL Server and Exchange Server, I want to use the Application-Aware feature.  It's my interpretation that Veeam will use either Applicaton-Aware for all of the VMs or VMware Tools Quiescence for all of the VMs in the backup job.  If my interpretation is correct, I will need to setup two backup …
Hi Everyone

What is the best DR plan using 2 Readynas in a VMware/Veeam environment?

I have a VMware 6.5 box running 2 VM's.  I use veeam replication to replicate to a iSCSI datastore which in on a LUN on the Nas1 box.   On the Veeam Box I run a backup job to iSCSI connection to another LUN on the same nas1.  Also running on the Veeam box is Veeam Office365 which backs up to another LUN on the same nas1.

On the main nas1 I have 3 ReadyDR jobs which run to a second readynas of the same type.  I was looking at trying to replicate the LUN's from Nas1 to Nas2 but couldn't get the, to see each other.  I was initially using ReadyReplicate however this is not supported anymore by Netgear and I cant see the LUN's in ReadyReplicate any how.

My question is what is the best config?  What is the best DR plan if you have the following:

1 VMware box running 2 VM's with a iSCSI connection to a LUN on a Nas box
1 Workstation running Veeam Backup Up and Replication and Veeam Office365
2 x readynas 8TB


Dear Sir,

We had a Veeam Backup and Replication 8 and using MS SQL Server 10.50.2500 (Microsoft SQL Server Express Edition (64-bit) which is not compliance to company's policy. I had installed MS SQL Server 2014 with SP2 (12.0.5571) on another server.

Anyone have experienced how to migrate the VEEAM configure database from MS SQL Express to MS SQL Standard edition? How the VEEAM pointing to the new database server?Please help.

With regards,
I have a laptop that is dead but I do have a Veeam full computer backup and I wanted to restore the volume from the old laptop to the new laptop (different hardware - one is a Latitude 5580 and the new is a 5590).  I did see this article and followed it, but it's a physical laptop, not a VM:

I used the recovery media from the new laptop and restored the C:\ volume from the backup - no errors in this process but when I boot the new laptop, Windows wants to try and do a repair (Preparing Automatic Repair) but can't.  I did have to use there "manual restore" option and map the C:\ since the volume info on the old laptop is most likely different from the volume info on the new.  Any ideas?  My guess is there's something wrong with the partition so it can't boot off of it.
Is there any free tool for backing up Exchange Online ?

For Veeam Backup for Microsoft Office 365, does it count for number of users on Exchange online ?

At present, we have 300mailbox with total size of 1TB. Which solution is suggested ? Will backup to premise is not possible in our case due to huge amount of data move through the network.

For Veeam Backup, can it backup by incremental ?


We have moved from BackupExec to Veeam and currently backup 10 x VM's and 5 physical servers.

Our backup repositories includes local disk, remote NAS and a robotic tape library.

I have been trying to work out the best practices for the requirement which is a follows.

Backups are Monday to Friday from 10pm.
Monday to Thursday are incremental, Friday are full backups.

We would like to store the backups on the local disk each night, copy incrementals to the NAS and over the weekend copy all of them to tape which is removed offsite and rotated each month.

If anyone has a suggestion on how to do this that would be great.
We presently have two UCS and EMC data domain systems.  One of them is in our colo and the other is our site.  We wanted to verify the pros/cons with going with either Avamar or Veeam or possibly another solution to replicate data and especially our virtual machines.  Our EMC data domain houses about 1 TB of data although our capacity is between 25 or 30 TB.  

Can someone offer some suggestions as well as alternatives to Avamar and Veeam?  Price will be a big concern as well.
Dear All

              i have a issue when trying to restore from tape from veeam, when i choose a restore point from backup tape, i received below "there is not enough space for backup files", any help would be appreciated, thanks
