NTbackup & large files

Is it possilbe to break up large files onto multiple tapes?
As in 90gig file onto three 40gig tapes?

When I tried the report reads:
Backup started on 5/24/2005 at 7:16 PM.
Warning: Unable to open "F:\SBS2003-inc.bkf" - skipped.
Reason: The system cannot find the file specified.

NTbackup indicates the file size to be 90MB not 90Gigs. Very strange!?!

Thank you for any help you can provide!
have a wonderful day,

Hello Volker,

Thank you for posting to the SBS Newsgroup.

Can I confirm with you that the problem is that the backup file is 90GB
which exceeds the capacity of your tape drive and you cannot backup it to
several tape drives?

Actually in SBS 2003, backup runner does not support spanning to multiple
tapes, you need to use the NTBackup tool to schedule a backup. To do so,
please see:

[Note]: Do not compress the file.

NOTE: The Task Scheduler service must be running before you can schedule a
backup. If the Task Scheduler service is not already running, start it. To
do so, click Start, click Run, type "cmd" (without the quotation marks) in
the Open box, and then click OK. At the command prompt, type "net start
schedule" (without the quotation marks), and then press ENTER.

To schedule a daily backup job in Windows Server 2003:

1. Log on as administrator or as a member of the Administrators group.

2. Click Start, point to All Programs, point to Accessories, point to
System Tools, and then click Backup. The Backup or Restore Wizard starts.

3. Click Advanced Mode.

4. On the Welcome tab, click Backup Wizard (Advanced) to start the Backup
Wizard, and then click Next.

5. Click "Back up selected files, drives, or network data", and then click

6. Expand My Computer, click to select the check boxes next to the drive,
folder or file that you want to back up, and then click Next.

7. Specify the backup type, destination, and name in the appropriate boxes,
and then click Next. For example, C:\Backup.bkf. NOTE: If a tape drive is
not connected to your computer, File is the only backup media type that is
available in the "Select the backup type" box.

8. On the "Completing the Backup or Restore Wizard" page, click Advanced to
specify additional backup options.

9. Specify the type of backup that you want to use, and then click Next.

10. If you want to verify the backed-up data after the backup operation
finishes, click to select the "Verify data after backup" check box. Click
any other options that you want on the "How to Back Up" page, and then
click Next.

11. Click "Replace the existing backups", and then click Next.

12. Click Later. Type a name for the scheduled backup job in the "Job name"
box, and then click Set Schedule. The Schedule Job dialog box appears so
you can configure when and how frequently you want the backup to occur. For
example, you can schedule the backup to occur every Friday at 10:00 P.M.
You can also configure multiple schedules for a task if you click to select
the "Show multiple schedules" check box.

13. Click the Schedule tab. In the Schedule Task box, click Daily, specify
a time in the "Start time" box, and then click OK.

14. In the Set Account Information dialog box, verify that
<ComputerName>\Administrator is displayed in the "Run as" box, type the
password in the Password and the "Confirm password" boxes, and then click
OK. NOTE: If the Task Scheduler service is not set to start automatically,
you may first be prompted if you want to start Task Scheduler. If this
occurs, click Yes, and then the Set Account Information dialog box appears.
Because the Task Scheduler service automatically runs programs in the
security context of a valid user for the computer or domain, you are
prompted for the name and password with which the scheduled backup job will
run. For scheduled backup jobs, you must supply a user account with the
appropriate permissions to gain access to all the folders and files that
you want to back up. The instructions in this article use the Administrator
account to run the scheduled backup job.

15. Click Next.

16. The options that you selected are displayed on the "Completing the
Backup Wizard" page. Make sure that these options are correct, and then
click Finish. The backup job that you scheduled is displayed in the
calendar on the Schedule Jobs tab. The scheduled backup job automatically
starts at the time that you specified.

If the issue persists, please gather following logs to the Newsgroup for
further research:

1): Event Log. Run "eventvwr", see whether there is any application logs,
if yes, please paste full content.

2): Backup Log.

A: Backup all files in C:\Documents and Settings\SBS Backup User\Local
Settings\Application Data\Microsoft\Windows NT\NTBackup\data\, and then
delete them.

B: Reproduce the issue.

C: Paste the full content of the files in the folder C:\Documents and
Settings\SBS Backup User\Local Settings\Application Data\Microsoft\Windows

D: Paste the error messages in event logs.

Hope this information helps. I am looking forward to your reply.

Best regards,

Brandy Nee
