Amanda Enterprise 3.3.5 Release with Hyper-V and Vaulting Support

Friday, December 6th, 2013

Our objective with Amanda Enterprise is to continue to widen its umbrella to protect most common IT infrastructure elements being deployed in the modern data center. We also seek to support various workflows for secondary and tertiary data as desired by the IT administrators. The new release of Amanda Enterprise (3.3.5) comes with two key features for these objectives.

Hyper-V Support

Hyper-V is a native hypervisor, which is getting increasingly popular especially in Windows server-centric IT shops. Amanda Enterprise now supports image level backup of live VMs running on Hyper-V. We support Hyper-V which is installed as a role either on Windows Server 2012 or Windows Server 2008.

One license for Zmanda Windows Client and Zmanda Client for Microsoft Hyper-V enables you to backup an unlimited number of VMs on one hypervisor. You need to run the Zmanda Windows Client on the hypervisor, and configure backups of VMs via Zmanda Management Console (GUI for Amanda Enterprise). ZMC discovers the VMs running on each hypervisor. You can choose whether you want to backup all or a selected set of VMs on each hypervisor.

A full consistent image of the VM is backed up to media of your choice - disk, cloud storage or tape.

Of course, you can continue to install and run separately licensed Zmanda Clients within your virtual machines (guests) to perform finer granular backups. This enables you to recover from smaller disasters (like accidental deletion of a file) without recovering the whole VM. You can consider having different schedules for your file-level or application-level backups and VM level backups - e.g. file-level backups may be performed daily and VM level backups may be performed each weekend.

Vaulting Support

While many of our customers have already implemented disk-to-disk-to-cloud (d2d2c) or disk-to-disk-to-tape (d2d2t) data flows using our products, we have formally introduced Vaulting as a feature supported via Zmanda Management Console. There are two key use cases supported by this feature:

  • Backup to disk and then Vault to lower cost disk or remote disk (via NFS)
  • Backup to disk and then Vault to cloud or tape for offsite storage

Our implementation allows very flexible media duplication (e.g., you can vault from multiple disk volumes to a smaller number of physical tapes). You can also choose to vault only the latest full backups for off-site archiving purposes. All storage devices supported by Amanda Enterprise can be a source or destination for vaulting (e.g., for one of the backup sets you can vault to a tape library and for another backup set on the same backup server you can vault to cloud storage). The Backup catalog of Amanda Enterprise keeps tracks of various backup copies and will allow for restoration from either the backup media volumes or vaulted volumes.

Note that vaulting is most useful when you want to duplicate your backup images. If you want to have a data flow to periodically move your backups e.g. from disk to cloud, you can simply use the staging area in Amanda Enterprise and treat the storage on staging area as your first backup location.

In addition to above new features, Amanda Enterprise 3.3.5 has several bug fixes and usability improvements. If you are interested in learning more, you can join one of our upcoming webinars (next one scheduled on December 18th): http://zmanda.com/webinars.html
