Instant VM Recovery allows a user to make an application available as quickly as possible in the event of a failure, without the need for additional infrastructure or having to wait for a more time consuming restore process.
If your environment is not licensed for Storage vMotion or that process simply takes too long to get data back to the production storage, users can leverage PHD Motion. PHD Motion does not require any special vSphere licensing. It leverages all the great things about the PHD full VM restore. When the user is ready to switch the running VM to the production storage, they simply perform a very small, planned downtime window to commit the changes from the temporary location to production storage and switch the VM over to the production data.
Application Aware Backups
PHDVB v6.0 provides the ability to take application aware backups for any application. Application aware backups include the ability to properly quiesce the application prior to backup, as well as perform any post backup processes, such as automated log management (truncate, shrink, etc). This is done by leveraging a very small guest application called the PHD Guest Tools.
With this functionality, PHD now has a very good message around backup and recovery for Exchange, especially when combined with the Digiscope solution for Exchange object recovery.
Prior to v6.0, PHD VBA provides a single backup mode called Virtual Full backups include source-side deduplication across all backups within a backup target.
While the Virtual Full is a high performing backup mode, there are certain configurations that are not optimized to handle the many files that the virtual full leverages. Therefore, PHD is implementing a traditional full / incremental backup mode for those configurations.
Email EnhancementsPHD Virtual Backup v6.0 will include several enhancements to email reporting for which users have a high demand.
File Level Restore Usability EnhancementsUsers will now be able to select an option to use CIFS for File Level Restore, whereby the backup will be mounted to the VBA and presented out as a CIFS share. The share will automatically be mapped to the machine triggering the file recovery and a Windows Explorer view of the backup data is presented to the user. This allows for easy access to backup data from almost any OS – Linux or Windows – for file and application level recovery. As always, security can be enabled on the CIFS share so the admin can restrict access to the backup data only to those that need it.
EncryptionThose requiring strict requirements for backup data security can now choose to enable one of many types of industry standard encryption levels for PHD Virtual Backups. When enabled, data will be encrypted at the file system level of the VBA to ensure that it is secure in transit to the backup target and at rest when it reaches the backup target.
Enhanced File and Application Item RecoveryDifferent users have different types of requirements for recovering files and making data available from backups to existing applications and application recovery tools. In v6.0, PHD Virtual provides an additional option for accessing files from backups that makes it easier to recover Linux files, as well as access data that requires permissions to be removed.
The installation package contains:
I configured the Appliance in my environment. Set the Time-zone, apply
the license and added a 100Gb thin disk to save the backups to and
started a new backup. I selected some of my important VM’s I want to
have backed up.Submit
the job and started my firsts backup on local disks attached to the
appliance. My lab runs ESX5i connected with Fiber Channel to my hardware
Nexenta CE box.The above process took me simply 10 minutes from scratch
to setup my first backup!!!
No deploying Windows templates, no SQL installation at all! saves time and licenses!
Now that you’ve installed and configured PHD Virtual Backup, you can:
The PHD Virtual Backup Exporter lets you export backup files from any existing backup storage location for long term or offsite storage. The PHD Exporter must be installed to a Windows Server machine using the included installation file. You only need to install the PHD Exporter if you plan to export backups to another location – the PHD Exporter is not required to run Backups, Restores, or Replication.
PHD Guest ToolsPHD Guest Tools enable application aware processing for individual virtual machines including quiesce, log truncation, and the ability to run custom scripts. To install the tools, you will use the ISO file that is included with the PHD Virtual Backup installation package.
The speed of my backups is very good, I selected 5 VM’s to be backed up:
We just backed up 217Gb of Data on 31.4 Gb of disk space, deduplication ratio of 1:6!
Job completed in 1h 52 minutes
The Appliance is configured with 1vCPU and 1024Mb of memory. With
compression and deduplication enabled I can imagine this would be a
bottleneck.V
Next I configured the VBA with 4vCPU’s and 4096Gb of memory to handle the load and started a new test with the same VM’s:
The Appliance now used 2-3 CPU’s at 100% and all 4Gb’s of memory,
setting 4 CPU’s doesn’t have that much impact.. I think 2 would do it.
I selected three VM’s to my incremental Backup list and just run it a few hours after the full backup:
You can see the deduplication kicks in, the data being written to the backup disk is minimal.
I received The Backup Report of my incremental daily backup in my e-mail after it finished:
The ability to restore files is now possible thru a windows share:
It creates the share on the appliance to be accessed to restore single files
Of course full VMDK backups can be restored on any data store you want:
PHD Virtual Backup v6.0 has matured and is improved with a nice new set of features. Feels very stable and is fast. But the best part again… It is an appliance. No single Windows or MSSQL license required.
PHD Virtual Backup allows you to easily deploy multiple Virtual Backup Appliances and thus creating an unprecedented scalability, without the cost and complexity that other solutions entail.
