In the original released version of Windows Server 2003, the initial shadow copy storage area that is allocated for shadow copy creation is 100 megabytes (MB). In Volume Shadow Copy service, you can use the shadow copy management tool, or you can use the vssadmin command. The differences are also copied in the shadow copy storage area. The shadow copies are implemented by using a copy-on-write implementation.

You are strongly advised to review the event log for any other potential Volume Shadow Copy service errors that might generate a writer failure. This hotfix addresses only the specific timeout errors that might randomly occur in Volume Shadow Copy service writers during backup. These conditions include a lack of disk space or improper configuration of the computer. Important Volume Shadow Copy service writers may fail with similar errors because of other conditions. When this problem occurs, shadow copy creation fails. The writers do not wait the time interval before they write. The writers do not flush their data buffers. However, if there is low CPU speed, high memory usage, or high input/output levels, you may experience the following behaviors: The writers wait to write so the contents of the shadow copy will be consistent with their data buffers. Also, some Volume Shadow Copy service writers, like the Exchange writer, wait to write for a predefined time interval so the shadow copy can be created during the time interval. The inter-process calls make sure that all the important Volume Shadow Copy service writers (programs such as SQL, Exchange Server, operating system services, and others) flush their data buffers during shadow copy creation. Shadow copy creation includes a complex sequence of inter-process calls. This problem occurs especially on computers that have slow hard disks, low memory, or low CPU speed or on computers that have the disk write cache disabled (for example, on a domain controller computer). You may experience a problem that causes certain Volume Shadow Copy service writers to time out during a lengthy shadow copy creation. Volume Shadow Copy service writer time-out The symptoms that are described earlier in this article may occur for one of the following reasons: In the message, VolumeName is the name of the volume that is scheduled for backup.

See Oracle Database Installation Guide for Microsoft Windows for the list of supported operating systems.The shadow copies of volume VolumeName were aborted because the diff area file could not grow in time. Oracle VSS is supported on the same operating systems that are supported by Oracle Database. Thus, the Windows user must be able to log in as SYSDBA to the Oracle database instances managed by the writer service. The writer uses operating system authentication when connecting to a database instance. During installation, you can specify the Windows account under which the service must be started.

In addition, the Oracle VSS writer provides command-line options to install and uninstall the writer service. oradim.exe utility that sets up an instance, also starts Oracle's VSS writer utility to setup VSS writer instance for managing the given Oracle instance. Oracle VSS writer instances are created automatically during the setup of an instance. From the perspective of the database, the VSS writer is simply an OCI client. The Oracle VSS writer runs separately from the Oracle database instance.
