Rubrik Extending Deeper into the Enterprise Data Center.

Rubrik is committed to providing the same powerful UX and simpler interface for traditional enterprise workloads. Rubrik nows protect AIX and Oracle Solaris,
helping backup admins skip a generation and migrate that data to their storage archive of choice. I particularly like this because how Rubrik can be used to backup both AHV on x86 and on Power. Rubrik also announced support for AHV VSS snapshots.

For AIX support crafted connector with low resource and operational overhead. The connector supports granular folder/file level backups via filesets that integrate with SLA policies. Filesets are a logical construct based on Includes and Excludes. These are often around a direct path to a file or folder but can use wildcards for greater flexibility around what is included or excluded.

For example, you might backup /home on all servers on a daily basis, excluding .mp3 files. At the same time, you might backup other folders on the same servers on a weekly or hourly basis. Filesets can be customized to meet specific needs. While we recommend keeping them simple, there is a high degree of customization possible, especially via calling Pre/Post Scripts. Pre/Post scripts can also be configured to provide application-consistent backups.

For AIX, we’ve Rubrik’s initial support on the versions (7.1 and 7.2) and filesystems (JFS and JFS2).

AHV VSS Snapshots

While Rubrik has provided support for Nutanix AHV VMs since version 4.0, adaptive consistency for AHV VMs
is now provided in the following order of precedence:

1. Rubrik Backup Service (RBS) based VSS snapshot
2. Native AHV application-consistent snapshot
3. Crash-consistent snapshot

With AHV environments, Rubrik leverages Nutanix’s REST 3.0 API to drive an initial full backup followed by incremental-forever backups in the most efficient manner possible. Rubrik CDM interacts with Nutanix Changed Region Tracking (CRT) to query only the changed metadata regions between any two snapshots of a VM or virtual disk. The efficiencies gained through this approach are essential to taking incremental backups, and provide the added benefit of saving on read operations for full backups. Utilization of parallel streams to rapidly ingest data magnifies these efficiencies, minimizing impacts to production workloads to near-zero levels. Supporting this level of performance at scale, Rubrik’s distributed architecture enables linear scaling of
throughput processes. Though straightforward in its architecture, the Rubrik integration with Nutanix delivers granular RPOs and application-consistent backups while automating the protection and restore workflows. With no hypervisor stun and both companies parallel streaming approach rapidly ingests the snapshot disks’ data into Rubrik’s Atlas filesystem.

Additionally, using VSS snapshots with Rubrik also provides app-consistent log truncation for Exchange – it automatically check to see if logs are backed up, and if done, truncate the logs up to the nearest point when the backup commenced. Rubrik doesn’t require specific settings to be turned on to allow app-consistent log truncation. Log truncation prevents the VM from running out of disk space and eventually crashing.

Demo: ESXi Backup with Nutanix Snapshots with HYCU

In addition to the support of Nutanix clusters that use Nutanix native AHV hypervisors, HYCU introduces the support for Nutanix environments that use VMware ESXi hypervisors. By using the native Nutanix storage layer snapshot technology, VMware snapshot stuns are avoided.

HYCU – Backing up virtual machines from Replicated Nutanix Snapshots

In remote office/branch office (ROBO) environments, HYCU allows you to back up virtual machines from their replicas on the central site Nutanix cluster. Backing up data from replicas without having to transfer the virtual machine data twice frees up WAN bandwidth for other business processes.

To be able to back up virtual machines from their replicas, make sure that the replication retention on the Nutanix cluster is adjusted to the backup policy’s RPO. This allows HYCU to use the Changed Region Tracking (CRT) feature to get a list of changed data since the last snapshot and perform an incremental backup. For example, if the Nutanix schedule interval is two hours and the RPO of the HYCU backup policy is eight hours, the retention policy for the remote site must be set to 4 or more snapshots (that is, at least the last four snapshots must be kept).

    The Wish List for Nutanix Centric Enterprise backups?

    I was asked today what I would look for for in a solution that was Nutanix focused for backup. Just quickly spit balling I came up with the following list:

    Backup vendor must use ABS to eliminate the needs for multiple proxies or solve this using a similar method.

    Backup vendor must support or show a road map of supporting AFS change file tracking? Minimum of supporting NAS backup

    Backup vendor must support backing up volume groups.

    Backup vendor must support backing up Nutanix snapshots that have been replicated from a remote site to a primary DC.

    Backup vendor must support Change Region Tracking for AHV. ESXi is a plus.

    Backup vendor must support synthetic full backups.

    Backup vendor must have native support for X APP, list your App like SQL.

    Backup vendor must have an open API.

    Got any others to add?

    NetBackup Got Upgraded: Modern Workloads use Parallel Streaming.

    A new capability in NetBackup 8.1 is its ability to protect modern web-scale and big data workloads like Hadoop and NoSQL that generate massive amounts of data. With the new Veritas Parallel Streaming technology, these modern scale-out workloads can be backed up and protected with extreme efficiency by leveraging the power of multiple nodes simultaneously. The result is that organizations can now adopt these modern workloads with confidence, knowing that their data, even in massive volumes, will be protected. And since new workloads can be added via a plug-in rather than a software agent, organizations can add new workloads without having to wait for a next NetBackup software release. NetBackup Parallel Streaming also supports workloads running on hyper-converged infrastructure (HCI) from Nutanix, as Nutanix and Veritas have partnered to certify protection of those workloads on HCI.

    source


    Netbackup takes care of utilizing all of the Nutanix storage controllers. NetBackup will mount using NFS of the local storage controller for each node removing the need for a proxy host.

    For some general best practices with the first release of this plugin:

      * Apply limit to backup maximum n*4 VMs concurrently, where n is number of nodes in the Nutanix cluster. 16 node cluster than would have 64 VMs being backed up concurrently.

      * Use Media Server as Backup Host if possible.

    Note: If VMs are powered off, then Prim element VIP will be used.

    Automatically Snap, Clone and Backup AFS (Acropolis File Services)

    I wrote a script on the Next community site that automatically snaps, clones and then you can use any backup product that can read off a SMB share. The script can be used to always have the latest backup copy and avoid impacting your production users.

    Automatically https://next.nutanix.com/t5/Nutanix-Connect-Blog/24-Hour-Backup-Window-with-Nutanix-Native-File-Services/ba-p/23708

    Hope you find it useful.

    HYCU v1.5 – Nutanix AHV Backup gets new features

    HYCU v1.5 has been released by Comtrade.

    The biggest one for me is ABS support! Know you can use cheap and deep storage and drive all of the storage controllers. Remember that ADS works with ABS so its a great solution.

    The following new features and enhancements are available with Hycu version 1.5.0:

    Backup window
    It is now possible to set up a time frame when your backup jobs are allowed to run (a backup window). For example, this allows you to schedule your backup jobs to run on non-production hours to reduce loads during peak hours.

    Concurrent backups
    You can now specify the maximum number of concurrent backup jobs per target. By doing so, you can reduce the duration of backups and the amount of queued backup jobs.

    Faster recovery
    Hycu enables you to keep snapshots from multiple backups on the Nutanix cluster. Keeping multiple snapshots allows you to recover a virtual machine or an application quickly, reducing downtime. If your know Commvault Intelisnap, very similar benefits

    iSCSI backup target
    A new type of backup target for storing the protected data is available—iSCSI, which also makes it possible for you to use a Nutanix volume group as a backup target. You can use the iSCSI backup target for backing up the Hycu backup controller as well.

    Improved backup and restore performance
    Hycu now utilizes Nutanix volume groups for backing up and restoring data, taking advantage of the load balancing feature offered by Nutanix. Therefore, the new version of Hycu can distribute the workload between several nodes, which results in increased
    performance of your backup and restore operations, and reduced I/O load on the Nutanix cluster and containers.

    Support for AWS S3-compatible storage
    Hycu enables you to store your protected data to AWS S3-compatible storage.

    Shared location for restoring individual files
    You can now restore individual files to a shared location so that recovered data can be accessed from multiple systems.

    Support for Active Directory applications
    In addition to SQL Server applications, Hycu can now also detect and protect Active Directory applications running on virtual machines. You can view all the discovered applications in the Applications panel.

    Expiring backups manually

    If there is a restore point that you do not want to use for a data restore anymore, you can mark it as expired. Expired backups are removed from the backup target within the next 24 hours, resulting in more free storage space and helping you to keep your Hycu system clean.

    Support for Nutanix API changes

    Hycu supports Nutanix API changes introduced with AOS 5.1.1.1

    SRM and Commvault Health Check

    The NCC health check pds_share_vms_check verifies that the protection domains do not share any VMs. It would be good practice to run this healh check after configuring either SRM or using Intellisnap from Commvault. It’s one of over 200 hundred checks NCC provides.

    This check is available from the NCC 2.2.5 release and is part of the full health check that you can run by using the following command:

    nutanix@cvm$ ncc health_checks run_all

    You can also run this check separately by using the following command:

    nutanix@cvm$ ncc health_checks data_protection_checks protection_domain_checks pds_share_vms_check

    A protection domain is a group of VMs that you can replicate together on a desired schedule.

    A VM can be part of two protection domains if the following conditions are met:

    A protection domain (Async DR or Metro Availaibility) is created, and the VM is added as a protected entity of this protection domain. The vstore containing the VM is protected by using ncli or by an external third-party product such as Commvault or SRM. Protecting a vstore automatically creates a protection domain. These protection mechanisms are mutually exclusive, which means that the backups of the VM might fail if the VM is in 2 protection domains.

    Solution

    If the check returns a FAIL status, the reported VMs need to be removed from some of the listed protection domains, so that they remain only inside one protection domain.
    If your using metro availability you may have move the VM to another container or stop protecting the vstore.
