Issue



Backup Exec (BE) 2010 or Backup Exec for Windows Servers (BEWS) 12.5 with Hotfix 331998 are unable to backup System Reserved partition on a Windows 7 or Windows Server 2008 R2.


Error



V-79-10000-11226 AOFO: Initialization failure on: "Shadow?Copy?Components" Unexpected provider error.
V-79-57344-65225 - AOFO: Initialization failure on: (0xE000FEC9): A failure occurred accessing the Writer metadata.
 


Cause



When Windows 2008 R2 is being installed, an unnamed Recovery Partition (usually 100MB) is created. This is a System Reserved only created to backup the OS boot files.
When AOFO tries to back it up, it uses the Volume Shadow Copy Service (VSS) - through the "ASR Writer" - to create the OS snapshot. If the Partition is named as a drive, the snapshot shouldn't have a problem performing the backup.

However, if the System Reserved partition is NOT named, Backup Job fails with this error.


Solution



Attention:

Before performing any troubleshooting related to this Technote see the Product Compatibility Information for Windows 7 and Windows 2008 R2 on the Related Technotes.

 






Workaround to avoid error messages without backing up the System Reserved partition:

When setting up the Backup Job, have an exclusion of the path C:\boot so it is not backed up.

Or

Workaround to backup up the System Reserved (\boot) partition:

- On the Computer/Server Manager > Disk Management > Assign a drive letter to the System Reserved partition.

 


- vssadmin list volumes may be used from the command prompt to verify volume's path

C:\Users\Administrator>vssadmin list volumes
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool
(C) Copyright 2001-2005 Microsoft Corp.

Volume path: P:\
Volume name: \\?\Volume{a2b716d3-8c1f-11de-a5ed-826d6f6e6973}\
Volume path: C:\
Volume name: \\?\Volume{a2b716d4-8c1f-11de-a5ed-826d6f6e6973}\
Volume path: D:\
Volume name: \\?\Volume{75c2418c-8c0e-11de-ae3c-001143dd2544}\


All the partitions should be listed. If this is set you may also set a Shadow Storage for the System Reserved partition (100MB). ShadowStorage basically sets aside space on a volume to store snapshots of a volume.

In this example I'm going to store snapshots of P: on D:

vssadmin add shadowstorage /For=P: /On=D: /MaxSize=XGB  ( X represents a Administrator's configurable choice)
