Resolution

We plan to resolve any product defect with symsnap.sys by providing an upgrade path to System Recovery 2013 R2 without the further investigation for this driver issue on System Recovery 2011 or earlier.

Customers with a valid maintenance license can get upgraded to System Recovery 2013 R2 or the latest System Recovery version.

For customers with valid support agreements (without maintenance) who have encountered an issue with the symsnap.sys driver, a free upgrade to System Recovery 2013 R2 will be provided once Technical Support have confirmed the issue is caused by symsnap.sys. The free upgrade is provided by End of Support Life (EOSL) date for System Recovery 2011. 

In addition to fixing your current issue (by upgrading), SSR 2013 R2 also offers the following benefits:

  • Support for Windows Server 2012 and Windows 8
  • Support for VMware vSphere 5.1
  • UEFI Support: System Recovery now enables boot from UEFI Unified Extensible Firmware Interface) in addition to BIOS.
  • 64 bit Support:  Full 64 bit support is now included.
  • Advanced Monitoring and Reporting: System Recovery Monitor is a new monitoring solution that's extremely simple to use and is FREE of charge to all System Recovery 2013 customers. It's a standalone and lightweight solution for managing up to 100 nodes. It’s simplicity and no extra dependency eliminates the learning curve for users. Intuitive GUI along with essential action controls provide crisp status along with ability to take desired actions seamlessly through the same view.
  • Smart Reconciliation:  Now backups and reconciliation are efficiently done by smartly tracking changed blocks. The reconcile time is drastically reduced to seconds by eliminating the need to do a complete reconcile in cases of crashes or abrupt shutdowns. In addition,  incremental backups are now up to 750% faster.
    - Incremental Backup without reconcile – At least 35% faster than System Recovery 2011
    - Full Backup – At least 15% faster than System Recovery 2011
    - Incremental Backup with reconcile – At least 750% faster than System Recovery 2011
 

 

Issue/Introduction

One of the key driver modules (symsnap.sys) of the existing System Recovery (SSR) 2011 product had a limiting design and needed a code restructuring. We have put in extensive work in System Recovery 2013 R2 to rewrite this code. This is a massive code change which cannot be back-ported without risking customer environment stability. This enhanced product area has been deployed in a large number of customer environments since early 2013 and has been well proven in the field.
