  • Page 2: Executive Summary

    Executive summary HP StoreOnce Backup Systems and Quest Software’s vRanger deliver an efficient, high performance, and robust solution for backing up and recovering VMware environments. vRanger provides simple management and powerful protection management features. StoreOnce Backup Systems provide a high-performance deduplicating disk backup target.

  • Page 3: Hp Storeonce Deduplication Technology

    For reliability and ease of management the StoreOnce Backup System are built on HP ProLiant machines and HP disk systems. The unique HP StoreOnce software is optimized to this platform. It is important to ensure the firmware and software in the StoreOnce Backup Systems is fully up-to-date.

  • Page 4: Hp Storeonce Replication Technology

    HP StoreOnce replication technology Replication enables a copy of the backup data to be created at a second location. This remote copy is most commonly used for disaster recovery (DR) and copy to tape. The replication is bandwidth optimized by the deduplication technology.
  • Page 5 Figure 2: vRanger Hot Add backup mode Physical proxy This configuration is for larger environments, and delivers the highest performance for ESX and ESXi servers. This architecture runs vRanger on a dedicated physical machine connected to the VMware shared storage. A performance advantage of the physical proxy is that it offloads the backup processes from the VMware servers and enables a LAN-free backup.

  • Page 6: Change Block Tracking

    Service Console based This is for any size environment, but is only possible on ESX servers. vRanger can be installed inside a virtual or physical machine. vRanger requests a snapshot of the virtual machine and then initiates direct copy of the virtual machine from the ESX server console to the vRanger Repository.

  • Page 7: Quest Vranger Active Block Mapping And Hp Storeonce Backup System Deduplication

    Figure 5: Enable Change Block Tracking in vRanger Quest vRanger Active Block Mapping and HP StoreOnce Backup System Deduplication The vRanger backup and replication engine ignores whitespace (unallocated blocks or zero-filled blocks) by default. Additionally, vRanger offers the option to enable Active Block Mapping (ABM) on a per-job basis.
  • Page 8 Figure 6: vRanger Resource Management The configuration options available are: • Maximum number of task running on vRanger (>=1): This value limits the total number of simultaneous tasks for the vRanger machine. This is affected by machine type and hardware as well as deployment architecture. The default value is 100, which does not normally need to be changed as other limits take effect before this value is reached.

  • Page 9: Repositories

    StoreOnce Backup System Maximum Values for vRanger When configuring backup jobs to a StoreOnce Backup System, consider the following limits. This information is particularly relevant to the maximum number of tasks running per Repository setting described above. Figure 7: Maximum and guideline values for StoreOnce Backup Systems when used with Quest vRanger D2D4312 G2 D2D2502 G2 D2D2504 G2...

  • Page 10: Cataloging

    Figure 8: The view of the vRanger Repository contents The human readable format is helpful when restoring the Repository from a tape backup (see Figure 8). vRanger includes an option for encrypting Repositories, which should not be used when backing up to a Repository on the StoreOnce Backup System because encrypted data cannot be efficiently deduplicated.

  • Page 11: Integration Of Hp Storeonce Backup System And Vranger

    The purchase of a replication license for any StoreOnce Backup System entitles the purchaser to a license for StoreOnce Backup System Replication Manager software. HP Replication Manager is a standalone application that provides basic management capabilities in a replication environment and provides an easy way to monitor up to 300 StoreOnce Backup System devices that are in replication relationships.

  • Page 12: Physical Installation

    Physical installation The StoreOnce Backup System requires installation into a suitable rack. A rail kit, power cables and full instructions are included with the appliance. A supplied network cable should be connected to the 1 GbE LAN port identified in the installation instructions for the appliance.
  • Page 13 Create HP StoreOnce Backup System CIFS NAS Share For most StoreOnce Backup System and vRanger integrations, it is recommended to create one HP StoreOnce CIFS Share and use this as the vRanger Repository. If you want to use StoreOnce Backup System replication on a subset of your virtual machines you might consider creating multiple CIFS Shares and multiple vRanger Repositories.

  • Page 14: Backup Job Options

    Figure 12: Add HP StoreOnce Backup System CIFS Share to vRanger Use the “User” and “Password” defined when the Share was created. Make sure you use a fully qualified Domain Name in the “Server” field. Do not check the “Encryption” checkbox, as this will cause vRanger to encrypt the backups before writing them to the StoreOnce Backup System Share.
  • Page 15 Figure 13: vRanger backup job options Particular attention should be paid to the following options: • Compress backed up files should not be enabled. The compression process effectively randomizes the backup data stream, which results in a reduced deduplication ratio on the StoreOnce Backup System and a slower backup job. The StoreOnce Backup System will compress the backup data after deduplicating it to improve the Repository utilization.
  • Page 16 vRanger Retention Policy, Space Saving Technology, and Deduplication The Retention Policy should be set based on the number of recovery points from which the organization needs to be able to recover. Each recovery point is a previous backup. The parameter to define the number of recovery points is the Savepoint count.
  • Page 17 Consumes more network bandwidth Consumes less network bandwidth HP StoreOnce Housekeeping Housekeeping is a regular background task run by the StoreOnce Backup System to optimize the physical storage utilization by reclaiming space after backup data is deleted or expired by vRanger. After a deletion or expiration, any unique chunks are marked for removal and duplicate chunks are de-referenced to the deleted data.
  • Page 18 StoreOnce Backup System GUI, see Figure 17. The GUI also reports statistics on Housekeeping, which should be used to tune the Blackout Windows. Figure 17: HP StoreOnce Housekeeping configuration is set to have a daily blackout window between 8pm and 8am to coincide with the time vRanger backups are scheduled Housekeeping is an essential process to maximize the deduplication efficiency of the appliance;...

  • Page 19: Integration With Tape For Long Term Retention Of Backup Data

    Appendix 1—Certification Test results In the certification process, we used vRanger as both physical proxy (HP BL460 G1) and virtual machine (4 vCPU and 4 GB memory) with Hot Add. The goals of the testing was to: •...
  • Page 20 Figure 18: Backup—results Incremental vRanger efficiently removes whitespace (unallocated blocks and zero filled blocks) and deleted data before sending it to StoreOnce Backup System, which further enhances this with inline target deduplication. The deduplication ratio above is calculated as User Data Stored/Size On Disk. Remember that the original disk size for the selected VMDKs was 432 GB.
