If anyone is using HYCU to back up their AHV environment, please let me know your feedback. 1- Is the product good and acceptable solutions to back VM on AHV? 2- How was your restore experience, when you had to recover a VM or file or app data? 3- How is the support? 4- Is their documentation clear and easy to follow on any KB or DIY. Thanks a Bunch
The best way to know if your DR solution will work when you need it is to actually test the DR workflows, right? Of course a DR test can be disruptive so you’ll want to understand the procedures and best practices before your testing window actually starts.The Async-DR solution built into your Nutanix cluster can handle both planned and unplanned failover scenarios. Testing these capabilities is not much different from simply using them when needed.The two most relevant documents for these procedures will be the Prism Web Console Guide and the Data Protection and Disaster Recovery best practice guide. The Prism Web Console Guide provides the execution steps for setup and failover, while the best practice guide provides additional detail on available solutions, requirements, and related considerations around space, bandwidth, and seeding, and a best practices checklist. After reviewing the requirements and scheduling a test window, you can follow the planned failover workflow in the Pri
Good Day, I am very new to Nutanix and recently purchased a cluster. It has only been running for about 30 days now managing my network and I am in the process of make some configurations to it. I need some assistance with an error message that I am receiving. I am using AHV as hyper-visor on my 3 node cluster. On this cluster I am running 5 Windows based Server VM's (not using Hyper-V or VMware). I followed the instructions from the Administration Guide by enabling VSS Shadow Copies on the Servers, then installing guest tools on all the servers and creating a protect domain Async DR. My configurations are working and snapshots are being created for my Domain Controllers and Application Servers. However, when a snapshot is trying to be created of my File Server, I keep getting the following error. "Warning : VSS snapshot failed for the VM(s) FS-01 protected by the FileServer in the snapshot (169035, 1563300389081879, 960) because Quiescing guest VM(s) failed or timed out. Impact
There are many situations when you might need to abort an ongoing disaster recovery replication job on your Nutanix cluster. You may be deleting the protection domain or maybe you added a large VM to an existing protection domain and now you don’t want to include this new VM’s baseline replication in the existing job, at least not before the weekend. Maybe the destination is running short of space and we need to stop adding to the problem. You can see the replication in Prism, but there’s no button to pause or cancel it. To abort the replication we will need to go to the CLI. This process is covered in https://portal.nutanix.com/kb/3272 SSH to a CVM in the cluster as the user ‘nutanix’, then run ‘ncli’ to get into this interactive CLI. First, list current ongoing replications with this command. You’ll need the Protection Domain name and ID from this output for the next command. <ncli> pd ls-repl-status You’ll need the Protection Domain name and ID from this output for th
It’s five-o’clock on Friday and the database admin has just let you know they’re working on a problem and need to keep last week’s Friday afternoon snapshot until further notice. If you do nothing that backup will expire in about an hour due to the protection domain schedule. How can we make sure this snapshot sticks around? Don’t worry! There‘s an NCLI command for this. You can change that snapshot’s expiration time to indefinite, and it will wait around until you delete it manually later. See the solution in the KB article here: https://portal.nutanix.com/kb/8594 First, you need the snapshot ID and the protection domain name. You can get this from the Prism UI, or from NCLI. To capture these details from Prism go to the Data Protection dashboard, Table view, Async DR tab, and select the protection domain from the table here. In the lower panel click on Local Snapshots and find the snapshot with the right Create Time. The number in the ID column is the snapshot ID you need, alo
Trying the veeam AHV appliance, i had a crash whilst taking a backup now am left with orphaned snapshots on a PAID ACCOUNT, and nutanix sends the ball to veeam back to nutanix, so here i am Protection Domain DP-QC-3 has 3 aged third-party backup snapshot(s) and may unnecessarily consume storage space in the cluster. i have a multitude of these and want to manually remove those snapshots, is there a process for this ?
We are currently considering implementing NearSync for a DR with an RPO of 15 minutes. Is there still a cluster limit of 40TB in 5.16? I can't find anything more specific in the documentation. https://portal.nutanix.com/#/page/docs/details?targetId=Prism-Element-Data-Protection-Guide-v5_16:wc-dr-near-sync-requirements-limitations-r.html The restrictions that backup tools like rubrik or netbackup cannot take normal snapshots when nearsync is active should be solved in 5.9 or not?
Looked around for new backup tools and found two interesting ones: http://www.nakivo.com/VMware-VM-backup-replication-recovery-software.htm And second Cloudbacko Cloudbacko shows a screen were a 1 TB is backup in 2 Minutes http://www.cloudbacko.com/en/cloudbacko-advanced-cloud-local-server-workstation-amazon-S3-google-backup-software-benefits.jsp
Configuring data protection and disaster recovery solution in your Nutanix environment is seamlessly simple and interesting. What if you have configured a remote site and have configured all the settings but still you are not sure regarding the configuration. Have you configured the vstore mapping correctly? Have you configured the network mapping correctly? Is there a check which can help me verify all the remote site configuration? Nutanix Cluster Check provides a check which helps you to verify the mapping configuration of a remote site. Give the following Knowledgebase article a read to know more about the check. KB-3335 Give the following documentation a read regarding best practises of DATA PROTECTION AND DISASTER RECOVERY to understand the configuration and limitations in-depth.DATA PROTECTION AND DISASTER RECOVERY
Getting the following error “VSS Scripts Not Installed” in your Nutanix environment with the description “VSS software or pre_freeze/post_thaw Scripts Not Installed”.Confused about VSS and the above-mentioned scripts?Let us help you understand the use of VSS for a snapshot!When you are enabling the Nutanix Guest tool, the following features VSS and Application consistent snapshot is enabled by default.Nutanix native in-guest VmQuiesced Snapshot Service (VSS) agent is used to take application-consistent snapshots for all the VMs that support VSS. This mechanism takes application-consistent snapshots without any VM stuns (temporary unresponsive VMs) and also enables third-party backup providers like CommVault and Rubrik to take application-consistent snapshots on the Nutanix platform in a hypervisor-agnostic manner. What’s the use of pre_freeze/post_thaw then? Within a Windows VM, NGT will use the Microsoft VSS writer built into the OS to quiesce the VM to take the app consistent snapsho
We’re in the process of testing Veeam for AHV on our NTNX running AOS 5.10. So far with Windows issues we have had very few issues and we worked them out quickly. However with a Linux VM running Ubuntu we’re getting errors on the Nutanix where the snapshot is checking for pre-freeze and post-thaw scripts. We’ve attempted a variety of ways to get those scripts in place, but it seems that there is no clear path. Does anyone else have experience with Veeam for AHV and backing up Linux VMs? Does anyone have any info on setting up the pre-freeze and post-thaw scripts? While we have some experience with this on Linux we’re certainly not experts.
Netbackup 8.1 was released yesterday. One of the features is "NetBackup for Nutanix – Parallel, scale-out backups of Nutanix clusters". Seems to only support full backups. There also is a requirement of a Linux backup host of client: [url=https://www.veritas.com/content/support/en_US/doc-viewer.18716246-126559472-0.v127139966-126559472.html]https://www.veritas.com/content/support/en_US/doc-viewer.18716246-126559472-0.v127139966-126559472.html[/url] [list] [*][b]Backup_Host=[/b] The backup host must be a Linux machine. The backup host can be a NetBackup client or a media server. [*][b]Application_Server=[/b] [/list]
Netbackup 8.2 has announce release of NetBackup Accelerator support for Nutanix AHV. [b]What is Accelerator :- [/b] If the client has no previous backup, NetBackup performs a full backup and creates a track log. The track log contains information about the client’s data, for comparison at the next backup. At the next backup, NetBackup identifies data that has changed since the previous backup. To do so, it compares information from the track log against information from the file system for each file. For NTFS and ReFS file systems, it also uses the Windows change journal to help identify the data that has changed since the last backup. Accelerator uses the Windows change journal in two ways: To check for changes in the file system metadata, and to help detect which files have changed since the last backup The NetBackup client sends to the media server a backup stream that consists of the following: The client’s changed blocks, and the previous backup ID and data extents (block offset a
I have issue about Rubrik backup. I have monitored that some vms could not backup some days with alerts are same. However, some days work fine.[img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/10508755-dbb2-4d48-a12a-4bb18e04410c.jpg[/img][img]https://d1qy7qyune0vt1.cloudfront.net/nutanix-us/attachment/a6fad98e-7e72-44b8-8b57-38e325ea3cdf.jpg[/img]
Hello, First-timer here, I don't know if I'm posting on the right place, I'm sorry if I'm not... I have Acronis 12.5 Backup installed on a Windows Server 2019 Essentials 64 bits (that's installed bare-metal on a Lenovo SystemX 3650 M5). Attached to it, there's an IBM TS4300. I'm trying to figure how to backup the VMs running on my AOS 5.10.1 in the tape drivers inside the TS4300. I know I can install Acronis Agents on my Windows VMs, but I don't know if that's the answer for my question. And, if a disaster happens and I need to restore the Acropolis VMs from the tapes, how can I do it? Sorry if my questions seem too basic, but I'm googling for the desired infos all day long with no success up to now, so I'm asking for help here. Best regards,
Hi, Looking to see if it is possible to manually deploy the CVM to Azure for use with Cloud connect? Also what is the reliance on the classic deployment model? Why can't the CVM be deployed using the Resource Manager model? Microsoft have been pushing customers away from the classic model over the last few years, its likely that the majority of customer with mature Azure deployments won't be using the classic model.
We are moving away from VMware over to Acropolis and I was wondering what others have been using to backup their VMs under Acropolis, 3rd party wise? Under VMware, we had been using Veeam, but this is no longer a choice.Any comments/suggestions would be helpful.
Does anyone have thoughts on how backup and recovery will work with the Acropolis hypervisor? Our company is definitely interested in moving in this direction, but the simplicity of Veeam B&R has been great, and I do not want to move away from that unless there is a solution that provides all of veeams features.
