Vista backup failure - not enough storage - 8007000e

I have set Windows Backup in my Vista Home Premium for daily backups at 7
a.m. to an external hard drive. It has been working just fine six months.
Suddenly it began failing with the error:

Not enough storage is available to complete this operation. (0x8007000E)

The listed backup location, E:, is correct; that is the external hard drive.
It is 279GB in size, of which 178GB are free. The drive being backed up,
C:, is a 372GB drive with 216GB free. The backups have always been
incremental and used anywhere from several KB to half a GB each time. There
is plenty of storage available.

The same error happens now each time Windows Backup runs. The event log
shows the error, and looking back in time, I see that it started on Jan. 9,
2008. Two things happened on this date that may be related:

1. I just happened to do a restore on that date, from the backup drive,
using Windows Backup, of two files. The restore worked just fine and I see
no reason why this would cause the backup to stop working.

2. (Much more suspicious). Six automatic updates were installed, all
successfully, according to the update history. However, the event log shows
MANY entries relating to the installation of these updates, including early
ones that were ERROR entries and later ones that were just warnings.
Interestingly, the first such ERROR occurred only 15 minutes BEFORE my last
successful backup completed, and said this:

Windows Servicing failed to complete the process of changing update
943411-112_RTM_neutral_PACKAGE from package KB943411(Security Update) into
Staging(Staging) state

It appears that the auto-update system failed the first time it tried,
perhaps because WinBackup was running, and tried again later and succeeded,
causing WinBackup to begin failing.

Any ideas?

I had the same problem where Backup in Windows Vista started failing
with the following message:

File backup failed because a shadow copy could not be created. The
system might be low on resources. The error is: Not enough storage is
available to complete this operation. (0x8007000E).

Additionally, I got a similar error message when I would try to go to
Control Panel -> System and Maintenance -> System -> Advanced system
settings (a.k.a. System Properties) -> "System Protection" tab. It
would fail to load the information about existing restore points.

I believe the problem was caused by having too many restore points.
This can happen when you have installed a lot of windows updates
recently. This blocks Backup from being able to create the shadow
copies it needs.

I resolved the problem by deleting the extra restore points with the
following procedure:

Control Panel -> System and Maintenance -> Performance Information and
Tools -> Open Disk Cleanup -> "Files from all users on this computer" -
> "C:" -> "More Options" tab -> System Restore and Shadow Copies
"Clean up" button -> "Delete". This deletes all but the most recent
restore point (so make sure your computer is in a stable state before
you delete all your old restore points).

Hope this helps,

I have the same issue and I tried deleting the most recent restore
points,restarted and the same thing is going on. It seems that most
everything is going into disarray on my system. All most all things give that
same infamous error of out of space. Even though I have 2gb of ram and only
using about 22% of my main hard drive space. (the rest is on externals) The
ironic thing is that it started happening when windows update finally
installed an update that it has been having trouble installing for the past
month. So I guess it has something to do with the updates that were installed.
