Looking for a backup option

Hi, we are a IP Telephony company and we are looking for an option to have a better backup system on our servers.We currently have 2 servers running ESXi. One live server with all our VM for our clients and one backup server. Nutanix seems like a good option for us to be able to have a backup system always live and not having to boot up any VM manually.If I wanted to start using Nutanix what would you recommend as best practice for a switch from ESXi to Nutanix?I just started looking into Nutanix and it seems like a great option with all the redundancy and self healing feature. I was wondering where I can find prices for the OS or access to the technical support. I can’t find any option list of subscription or price range for their OS.

Remote site VM snapshot IP address

I have question about remote site's snapshot.When we restore the VM by snapshot from origal siteI have question about remote site's snapshot.When we restore the VM by snapshot from origal siteWhen we restore VM, it will probably be a clone of the original site's VM, so I can understand NIC MAC Address can be changed.However, I hope to know does IP addresses also be change or not.

Recommendations For Leap And Supported Service-level Agreements (SLAS)

Nutanix recommends the following best practices for implementing disaster recovery using Leap. Along with these recommendations, there are specific recommendations for data protection with Synchronous replication (0 RPO).For data protection with Synchronous replication recommendations, see Recommendations for Synchronous Replication.General Recommendations Create all Leap entities (protection policies, recovery plans, and VM categories) at the primary site, where the VMs exist. Upgrade the Prism Central before upgrading the Prism Element running on the clusters registered to Prism Central. Disable Synchronous replication before unpairing the sites.If you unpair the sites while the guest VMs in the Nutanix clusters are still in synchronization, the Nutanix cluster becomes unstable. For more information about disabling Synchronous replication, see Disabling the Synchronous Replication (from 5.12 to 5.17 only). Recommendation for Virtual NetworksDo not create virtual networks that hav

Data protection groups replicated to Azure

At a customer we have a single Nutanix 3-nodes Cluster running like a charm for a few years. All virtual machines are snapshoted by Prism, 3 times a day, and then replicated to a remote backup site which is Microsoft Azure. In Azure we have then a CVM and some blob storage to store backup replicas.I’m currently wondering our possibilities if a severe outage occurs on the site hosting the physical cluster leading to the loss of the hardware.I know that we could order a new physical cluster and then retrieve the snapshots externalized to Azure to rebuild the infra, but it means that the infra is down for a few weeks (supply time, etc...).Is there a possibility to restore externalized snapshots directly to Microsoft Azure VMs?

DR Solution for Oracle workload

On Nutanix cluster , our Oracle workloads are protected via Oralce Data guard. We are looking for some sort or block level replication solution to cut down the Oralce license cost for DR solutions.Does Nutanix or 3rd party application that work on Nutanix cluster  have any DR replication (block level) solution for Oracle and SQL server workloads with point in time recovery?I don’t think the protection domain is suitable for Database workloads. Please suggest DR replication solution available for VMs that runs Oracle/MSSQL database workloads.

VMs downtime on my remote snapshots using Disaster Recovery

I just want to know if there's a downtime on my Virtual Machines, for example my Main site have an outage then I have remote snapshots to DR site. The question is . . . is it automatically activated or powered ON my virtual machines inside on my remote snapshots or I need to manually activated or powered ON the virtual machines on my remote snapshots?

Async, NearSync or Metro - which one is the best?

The abundance of options causes anxiety. That’s a proven fact. It is only true, however, if those options are hardly distinguishable. This is not the case with Nutanix DR options at all as each feature has a clear purpose and application. It all starts with an SLA. Understanding your disaster scenarios and the amount of data that you are ready to lose in the event of the disaster is the key to choosing a solution that is right for you. Roughly, there are several main options: Local backups (also known as Time Stream). Use these to roll back any Guest OS maintenance that went wrong. Remove a snapshot when the maintenance is over and the rollback is no longer required. Do not leave your snapshots unattended. Remote backup and DR: Asynchronous Replication: Protection from VM Corruption and Deletion as well as from a total site failure. Snapshots can be 1hr or longer apart. Near-sync Replication - leverages Lightweight Snapshots that are snapshots of the metadata. Recovery points can

Veeam Backup Chain Break after Nutanix VM failover and back

I’m new to Nutanix and we are using Prism Pro to move a VM from one 6.7 Vmware farm to another and back again. That works 100% but Veeam V11 can not see the VM once it is moved. It’s like the UUID is wrong but I have checked that and it is ok (same) Support are looking into this and are saying this is a unique case… surely this must be common? If there is no solution we will end up with the same VM added to the Veeam backup job, again and again… I have tried using TAGS and direct add to veeam…

Async Protection Domain

Hi All, I'm wondering what configurations people have on Async Protection Domains? How many VMs per PD Create many PDs and group by application/department/roles eg[list] All Web servers in one group, all SQL servers, all application servers All HR based systems, All IT based systems, All Fiance based systems Is there a limit on how many PDs you can have in a cluster What's the dis/advantage to having fewer large PDs over many smaller PDs What frequency and retention are the local/remote snapshots What issues arrise when activating a PD I believe the IP address will be removed and the MAC will change...correct??, any scripts or automation applied?[/list] Thanks for any response you can give.

Commvault with Nutanix - Best Practices Checklist

Use a Nutanix cluster external Data Services IP address when using IntelliSnap. Install a VSA on every Nutanix compute node. Install the MediaAgent software on all the VSA proxies. Install CommServe and MediaAgent on a secondary Nutanix cluster to separate backup and production infrastructure to protect against failure. Follow Commvault sizing guidelines. Create a virtual server client proxy group for easier management. When using IntelliSnap, colocate the MediaAgent software with the VSA. With ESXi, when you add ESX hosts to vCenter, make sure that the format of the ESX host name matches the host name format in vCenter. For example: If the host name format is short name, use short name to add the host to vCenter. If the host name format is FQDN, use FQDN to add the host to vCenter. If the host name is an IP address, use the same IP address to add the host to vCenter. With ESXi, use NBD as the transport mode whenever possible. With ESXi, configure the management network interfaces t

Integrating 3rd party backup with Nutanix

Third party backup integration is data protection that involves creating snapshot and backup copies via third party backup software. The requirements for integration changed depending on the backup software being used. Some of the supported backup vendors are HYCU Veeam Commvault Cohesity Rubrik For full list please visit Alliances Partners within Backup & Disaster Recovery. This is a high level overview of the process. It consists of following components Backup Server Configuration database (usually deployed within the backup server or within the appliance (depends on the vendor)) Proxy (deployed within the NTNX cluster) Repository NTNX Cluster Following Services are involved in creating 3rd party snapshot  Apache Web Service - handles all API calls to and from the backup software Prism - tracks all API v1 and API v2 calls Aplos and Aplos Engine - tracks API v3 calls aplos_engine is responsible for the aplos snapshot (Snap UUID - kind UUID) creation Ergon -

Data protection Migration and failback

Hi, I’m new on the Data protection feature. I’ve done the a test VM migration to another nutanix cluster. The thing is after the migration, the VM on the source will be destroyed. I’m planning to use the Data protection to migrate the VM from the source cluster to the target cluster. I would need to failback the VM to the source VM. Am I able to restore the VM on the source site?

Any HYCU Users Here?

We are currently evaluating Nutanix and also HYCU for backup. So far HYCU looks really good running on my CE lab server but there is one issue that they cannot answer to. For file restores on older recovery points (past the "Fast Restore" point), HYCU must copy the entire VM from the storage target and mount it to even start the search for a file. While for small VM's this my not be a big deal, larger VM's would cause a wait time based on your network connection to the storage target. For anyone using HYCU is this a concern to you? I'm very interested in hearing real world feed back here. Thanks!

Nutanix replication or recovery with volume group

Hi Everyone,I want to know what nutanix version can do replication or leap recovery plan with volume group (iscsi)? I currently use the CE version for testing ,my Nutanix CE and PC version are NUTANIX 20190916.276.I'm testing the iSCSI space of volume group mounted on Windows Server,then execute the plan of leap failure. However, after my windows server fails to DR, there is no iSCSI space on the windows server, and I do not see that the volume group is sync to DR.Is there a problem with my configuration, or is the CE version not supported at present?Has anyone ever done this test?Thanks.

Nutanix Disaster Recovery Solutions

Nutanix offers a variety of DR solutions. The flowchart provides a detailed representation of disaster recovery solutions.  Leap with two Prism Centrals: Asynchronous replication: it enables you to protect your data with an RPO of 1 hour or beyond.The policy creates a recovery point of the VMs in every 1 hour (or in the hourly time interval that you specify in the RPO) and replicates it to the recovery site NearSync replication: It enables you to protect your data with an RPO of as low as 1 minute.The policy creates a recovery point of the VMs in minutes (1–15 minutes) and replicates it to the recovery site. You can configure disaster recovery with NearSync replication between two AHV or ESXi clusters at the same or different on-prem sites Synchronous replication: It enables you to protect your data with a zero recovery point objective (0 RPO).You can configure a protection policy with Synchronous replication by defining the VMs or VM categories that replicate all the writes on the pro

Restore recovery point in place in PC

Hi, I’m tryning to wrap my head arout the differences between Snapshot and recovery point on a functional perspective. My target is to take vmware like snapshot of my vm. For that i saw 2 possibilities :the recovery point, which are managed by PC and allow for easy replication The snapshot which, correct me of i’m wrong) can only be created in PC My issue is that the recvery point cannot be restored “in place”, I mean in the vm object itself, but only by creating a clone of the vm, this create a extra administrative burden if i have to restore a vm from a recent recovery point as i have to :restore/clone the recovery point into a new VM delete the old one update the clone with the previous name, categories, etc ….In addition the newly restored/cloned vm has lost all the previous recovery point However the snapshot can be restored in place, but they are not managed by PC and replicated to the backup cluster … TL;DR ; Is there a way to either create a snapshot via PC or restore in place

What Happens When Restoring Protection Domain Entities with Volume Groups

When performing a restoration of a VM with a volume group on a different cluster, changes are made to the guest OS in order to connect to the restored volume group.Since the primary site’s data services IP address will no longer be valid, the guest OS will connect to the volume groups using the secondary site’s data services IP address. Also, all other SCSI target IP addresses on the guest OS will be removed.Another change that occurs is the IQN of the VM. When the volume group is restored, the IQN is updated with the timestamp of when the volume group was recovered. This allows for multiple restorations of the volume group if necessary. Therefore, the IQN needs to be changed in the guest OS iSCSI configuration as well. The Nutanix Guest Tools (NGT) CD is mounted on the VM to facilitate this iSCSI configuration change so that no manual changes are required.More information about the above restoration process can be found in the Support Portal here.

Can Nutanix infrastructure create memory dumps from snapshots?

Hello, I am an engineer with a security software vendor. We have a mutual customer that seems be experiencing system hangs on their vms in use on their Nutanix Acropolis platform. Admittedly I am not very familar with Nutanix as I mostly work with Vmware. These hangs are reportedly occurring after they upgraded our security product. Vmware has a process where we can create snapshot files and convert them into a memory dump file. This is helpful for our troubleshooting effort when normally you cannot take any action within the vm image to force a dump. I am trying to find out if the Nutanix Acropolis infrastraucture has any comparable capability. I will be suggesting that our mutual customer reach out to you as well, but am trying to inverstigate capability in parallel. Your assistance and advisement is welcome. David Alexander

is it possible to retrieve a single snapshot from dr site instead of the entire policy?

when i do retrieve, i can do for the entire snapshot. but the snapshot contains a lot of vms and i only need one. so how can i pull just one?

Storage Containers vs. vStores

While learning AHV I’m a bit confused on a few things as it relates to vStores and Remote Sites. What is the purpose of a vStore and how do they differ from Containers? What are the implications of mapping a Site-A’s vStore (Container-A) to Site-B’s vStore (Container-B) that has running VMs in it? What are the implications of not including all VMs from within Site-A’s Container-A in a Protection Domain and failing-over said PD to Site-B?      - Will the unprotected VMs from Container-A continue to run in Site-A?      - What happens when I fail-back the PD to Site-A? Let’s say I’ve mapped Container-A (Site-A) to Container-B (Site-B). If I create a Protection Domain that contains VMs from Container-A2 (Site-A), how does this factor into my vStore mappings between sites? Thanks for the assist!
