Powershell: Change Veeam San Snapshot Options


In the case you want to use the Storage Snapshot feature with Veeam Backup, the feature will be enabled for all the Backup jobs and will be the default option to process a backup job.

We only want to enable the feature for certain jobs with a special name convention like SAN-BackupJob-01. So I created a small Powershell script to disable this feature for all the jobs without the special name convention.

The Powershell script below will return all the jobs where the job name not match the “SAN” search string. The next step is to disable the “Use storage snapshots” feature for the jobs.

Script: Disable-SanIntegrationOptions.ps1:

if((Get-PSSnapin -Name VeeamPSSnapIn -ErrorAction SilentlyContinue) -eq $null){
    Add-PSSnapin "VeeamPSSnapIn"
}

foreach($vbrjob in (get-vbrjob | ?{$_.Name -notmatch "SAN"})){
    Write-Output "Changing job: $($vbrjob.name).."
    $SanIntegrataionOptions = $vbrjob.GetOptions()
    $SanIntegrataionOptions.SanIntegrationOptions.UseSanSnapshots = $false

    $vbrjob.SetOptions($SanIntegrataionOptions)
}

From now on only the jobs that need the SAN Snapshot feature, can utilise this feature and all the other jobs will use the default processing mode.

Veeam: End of support Veeam 6.5 in Q4 2014 with the release of v8


A quote from Gostev, in the Veeam Community Forums Digest mailing, send on august 4:

If you, or your customers are still using B&R 6.5, please keep in mind that we will stop supporting this version along with our v8 release, which is planned for early Q4. So please take the opportunity of slow summer time to perform the upgrade to v7. New releases typically increase load on our technical support team, which may in turn increase response times to handle possible upgrade issues (although frankly, we are not getting a lot of those for v7).

So if you’re still using Veeam 6.5 in production. Start working on your RFC to upgrade to Veeam v7.

Release: Veeam Backup & Replication 6.5


Yesterday was the release day of Veeam Backup & Replication 6.5. The first backup solution with full support for vSphere 5.1 and Windows Server 2012 Hyper-V 3.0.

An overview of the new features can be found in the this Youtube video:

I think the following features and enhancements are worth an upgrade. If you’re running a vSphere shop.

Features:

Restore from SAN snapshots
Version 6.5 also introduces Veeam Explorer for SAN Snapshots, which provides granular VMware recovery from HP StoreVirtual VSA and LeftHand snapshots. Codeveloped with HP, Explorer for SAN Snapshots lets you perform Veeam restores (Instant VM Recovery, Instant File-Level Recovery and Explorer for Exchange item
recovery) of VMware VMs directly from array-based snapshots.

You can find a short demo over here:

 

Reminder: Although SAN snapshots can provide excellent RPOs (recovery point objectives) for certain operational disasters, they cannot serve as real backups since they would be lost along with production data in the event of a storage disaster. Thus, you should never rely solely on SAN snapshots for data protection. To ensure protection against all types of disasters, continue to perform regular backup of all VMs to backup storage using Veeam backup jobs or VeeamZIP™.

vSphere 5.1 support:

Veeam Backup & Replication 6.5 provides full support for VMware vSphere 5.1.
And like vSphere 5.1, Veeam Backup & Replication 6.5 supports VMs running
Windows Server 2012 or Windows Server 8.

Enhancements:

Engine:

  • Synthetic full transformation and reversed incremental backup. Improved performance (up to
    several times, depending on backup storage).
  • Storage optimization. New storage optimization setting provides improved performance and
    resource utilization for backup jobs with backup files over 16TB in size.
  • Memory consumption. Average memory consumption by the job manager process has been
    reduced up to 3 times.
  • Network packet loss. Increased the processing engine’s tolerance to network packet loss.
  • Network traffic verification engine. New network traffic verification engine detects and automatically recovers from in-flight data corruption caused by malfunctioning network equipment and similar issues.
  • Improved NAT support. Control whether the source backup proxy server or the backup repository/
    target backup proxy server establishes network connectivity. This is helpful when deploying Veeam
    Backup & Replication in a network with NAT and firewalls.
  • Storage space notification. Added support for low disk space notification for CIFS-based backup
    repositories.
    File-level restore
  • Direct file restore. When restoring a guest file back to its original location from the backup console
    (Backup Browser), perform the restore with a single click. You no longer need to supply destination
    information, and Veeam Backup & Replication does not have to stage the file locally on a backup server
    or on a network share.
  • Dynamic disks. Extended support for file-level restores from dynamic disks to include spanned,
    striped, mirrored and RAID-5 volumes.
  • Backup Browser UI. Updated the Backup Browser’s user interface (UI) to match the new product UI
    introduced in version 6.1. Removed the hidden system partition from the volume tree. Now retrieves
    actual drive letters from restored guest OS settings (rather than simply assigning in sequential order).

Enhancements specific to VMware:

  • Improved processing performance. Significantly reduced data transfer initialization time in all
    transport modes by disabling excessive VDDK logging.
  • Direct file restore. Perform a direct file restore (described earlier) without a network connection
    between the backup server and the destination VM.

You can read about the rest of the enhancements in the What’s new PDF here.

Personally I hope that I can find some time to test the Restore from SAN snapshots feature soon. We are running a huge Lefthand shop so this feature might become handy in the near future.
