Resolution

You can resolve this issue by deleting the registry key and allowing Backup Exec to use its default I/O buffer size.

Complete the following steps to delete the registry key.

Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry.

1. In Windows, click Start and then click Run.

2. Type Regedit.

3. Click OK.

The Registry Editor opens.

4. Navigate to the following path:

HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\Backup Exec For Windows\Backup Exec\Engine\NTFS\

5. Select the following registry key:

FsIOBufferSize

6. Right-click the registry key and then click Delete.

7. Click Yes to confirm that you want to delete the registry key.

8. Close the Registry Editor.

NOTE: If this registry key does not exist this then the issue is not related to FsIOBufferSize key.

 

 

 

Issue/Introduction

When you try to back up a disk, the job fails with the following error:
0xe000fe36 – Corrupt data encountered. See the job log for details.
The error can occur if you alter the Backup Exec NTFS BEDS plug-in’s input/output (I/O) buffer size using the “FsIOBufferSize” registry key.
Backup Exec uses unbuffered file I/O when you perform a backup job. If you use the registry key to manually configure the I/O buffer size, it must be a configured as a multiple of the disk sector size.
If the sector size that you want to back up is 512 bytes, Backup Exec can request any buffer size that is a multiple of 512. This includes the following buffer sizes, for example:
  • 512 bytes
  • 1,024 bytes
  • 1,536 bytes
For a 4K native disk, the sector size is 4,096 bytes. Therefore, Backup Exec can request any buffer size that is a multiple of 4,096. This includes the following buffer sizes, for example:
  • 4,096 bytes
  • 8,192 bytes
  • 1 2,288 bytes
If you back up both 512-byte and 4,096-byte disks, the buffer size should be an integer that is a multiple of 4,096. The smallest buffer size that you can use would be 4,096 bytes because 4,096 is a multiple of both 512 and 4,096.
If you configure an I/O buffer size that is not a multiple of the sector size of the disk or disks that you want to back up, the backup job fails.
