Backup Does Not Work with Error 800700B7 (312551)

This article was previously published under Q312551

SYMPTOMS

When you use the Msdmback.vbs script to back up a SharePoint Portal Server computer, you may receive the following error message:

Error: An error occurred during backup. See the event log for more details.
ErrNo: 800700B7
Desc: Cannot create a file when that file already exists.
Source: MSSearch.Admin.1

NOTE: Even though you receive this error message, no corresponding event ID message is logged in the Application event log or the System event log.

CAUSE

This issue can occur if you did not enter the file name for the backup file that you want the Msdmback.vbs script to create, for example, if you use the following syntax to initiate a backup (where c:\backupdir is the folder in which the backup will be created):

msdmback /b c:\backupdir

This syntax does not specify the name of the file that you want the script to create.

RESOLUTION

To resolve this issue, use the following correct syntax, which includes the file name that you want the Msdmback.vbs script to create to initiate a backup (where backupfile is the name of the file that you want the script to create):

msdmback /b c:\backupdir\backupfile
