We have one SBS 2003 R2 server that periodically fails a scheduled backup.
The failure as as follows;

2/11/2007 11:00 PM
-------------------------------
Date: 12/11/2007
Time: 11:00 PM
User: SYSTEM
-------------------------------

Backup Runner started.
Launching NTBackup: ntbackup.exe backup "@C:\Program Files\Microsoft Windows
Small Business Server\Backup\Small Business Backup Script.bks" /d "SBS Backup
created on 12/11/2007 at 11:00 PM" /v:yes /r:no /rs:no /hc:off /m normal /j
"Small Business Server Backup Job" /l:s /f
"G:\office.beachesfinancial.ca\Backup Files\Small Business Server Backup
(05).bkf" /UM
NTBACKUP LOG FILE: C:\Documents and Settings\SBS Backup User\Local
Settings\Application Data\Microsoft\Windows NT\NTBackup\data\backup06.log
=====================<BEGIN NTBACKUP LOG FILE>=====================
Backup Status
Operation: Backup
Active backup destination: File
Media name: "Small Business Server Backup (05).bkf created 12/11/2007 at
11:00 PM"

Volume shadow copy creation: Attempt 1.

Error returned while creating the volume shadow copy:0x8007000e.

Error returned while creating the volume shadow copy:Not enough storage is
available to complete this operation.


Aborting Backup.

----------------------

The operation did not successfully complete.

----------------------

=======================<END NTBACKUP LOG FILE>=====================
NTBackup finished the backup with errors.

For more information about failed backups, see the article on
troubleshooting your backup at the following Web page:

Backup ended at Tuesday, December 11, 2007 11:00 PM
Backup Runner finished.

When the backup is run manually everything works correctly. Also subsequent
backups run correctly.

Any ideas?

Hi - please post SBS questions in m.p.windows.server.sbs - it does a lot of
things its own way, including backups. When you post in there, please
include more info about the destination (G drive) you're backing up to,
also - you should get some help pretty quickly.
