Veeam Backup Interview Questions
| Question |
| Is there any advantage for veeam over netbackup or networker ? |
| Answer |
| Compared to other backup software, veeam has below mentioned benefits 1. Its a agent less software , when we want to take DB or other application related backup , agent is required in other backup softwares. Whereas Veeam does not require any agent to be installed for application backup like Oracle/SharePoint/Exchange etc. 2.If we take snapshot backup via Netbackup or networker, in order to perform GRT level backup, again client plugin should be installed, where as in Veeam without any plugin installation at client level we can take snapshot backup and restore file level and So on. |

| Question |
| Can you explain about the backup proxy server? |
| Answer |
| Backup proxy is a server which fetches the VM data (configuration files and virtual disks) from the production storage, processes the data by applying deduplication and compression, and sends it off to the backup repository (in case of backup) or another backup proxy server (in case of replication). Backup proxy is also used to write the VM data (configuration files and virtual disks) back to the production storage which is used for VM restores, and to create and update replica VMs for replication. |
| Question |
| How is Veeam Backup and Replication licensed? Do Veeam has different editions? If yes, features difference between these editions? |
| Answer |
| Veeam Backup & Replication is licensed per CPU socket on VM hosts that are being backed up and/or replicated. A license is required for each occupied motherboard socket as reported by the hypervisor API. Note: Target hosts (for replication and migration jobs) do not need to be licensed. |

| Question |
| Will veam support long distance replication..? If yes Wat is the network bandwidth requirement for long distance replication.? |
| Answer |
| yes veeam supports long distance replication ( WAN) Currently Wipro colud computing backup is implemented using Veeam, and the current replication speed is 6 mbps Its all depends on how we configure the backup and you network traffic. Network: 1 Gbps LAN for on-site backup and replication, and 1 Mbps WAN for off-site backup and replication recommended. High latency and reasonably unstable WAN links are supported. |

| Question |
| What will be the backup method for VM’s with RDM , as snapshot isnt supported on VM’s with RDM? |
| Answer |
| VMs with physical RDMs and independent disks cannot be backed up with Veeam Backup & Replication. In both cases, this is because VM snapshots cannot be applied. Veeam Backup & Replication performs its backup and replication tasks by issuing a VMware snapshot to the VM. Defining how an RDM is set up on a VM is decided during the add hardware wizard if the RDM is larger than the maximum VMDK size of the datastore that hold the VM’s configuration file; performing a snapshot on the VM with an RDM will fail. For VMs to be backed up with Veeam Backup & Replication, the virtual mode of the RDM must be used. VMs with a RDM in physical mode can’t have a snapshot taken against them |
| Question |
| If veeam can backup VM’s with RDM’s , which backup method it will use as snapshot isnt supported for VM’s with RDM??? |
| Answer |
| Physical RDM’s don’t support snapshots, so they are a “no-go” with Veeam. Veeam is a VM level backup product so it depends on VMware snapshots to work. |
