A snapshot copy backup of a storage group fails and Event IDs are logged in the Application log in Exchange Server 2003/2007/2010

SUMMARY

A snapshot copy backup of a storage group fails and Event IDs are logged in the Application log in Exchange Server 2003/2007/2010

ISSUE

Purpose

A snapshot copy backup of a storage group fails and Event IDs are logged in the Application log in Exchange Server 2003/2007/2010

Description

Problem occurs while performing exchange backup, Microsoft Exchange writer crashes while taking snapshot of Exchange with the following events ESE 206, MSexchangeIS 9611, ESE 2002, ESE 2007, Unitrends agent 284 and error code 0xfffffdd0 while freezing the Storage groups or Exchange database. Information Store (3484) Shadow copy instance 1 encountered error -560 on freeze

Cause

This problem occurs if the Exchange transaction log files are manually moved or are manually deleted from the transaction log folder when a storage group is running. The VSS process tries to delete each unnecessary log file after a full online backup. If the VSS process cannot find one of the log files, the backup fails and the backup in progress flag is not reset.

Resolution

To resolve this problem, follow these steps:

  1. Take a full Exchange backup. If  this action does not resolve issue, proceed to next step.
  2. On the affected Exchange server, stop the Microsoft Exchange Information Store service. Alternatively, dismount all the stores that are in the affected storage group.
  3. Run the eseutil/mh command against each database in the affected storage group. Do this to make sure that each database is in a Clean Shutdown state. (For more information about how to do this, visit the following Microsoft Web site: https://docs.microsoft.com/en-us/previous-versions/tn-archive/bb124570(v=exchg.65)).
    Note Do not continue this procedure until each database is in a Clean Shutdown state.
  4. Move all the transaction log files and all the system files from the transaction log folder to a backup location.
  5. Restart the Exchange server.
    Note This problem may cause the backup process to become locked. When you restart the computer, all active backup processes are exited.
  6. Perform a full online backup.
