How to configure shadow copy storage?

[Neil Jones]

Hi,

I was looking into the Event logs on my Vista system and found the
following error message:

"The shadow copies of volume C: were aborted because the shadow copy
storage could not grow due to a user imposed limit."


After I perform a disk clean and delete the shadow copies, my System
drive (C is about 26GB.

How do I increase the shadow copy storage and avoid this error message?

Thank you in advance. Wish you all a Happy New Year!

Regards,

NJ

Shadow storage is controlled by the command-line utility vssadmin. Click
Start. In the search box type cmd and press Ctrl+Shift+Enter to run command
as an administrator. At the command prompt type: vssadmin /? to see the
options. Vssadmin list shadowstorage will show you the amount of shadow
storage allocated and used. Vista be default uses up to 15% of a drive's
available space to save restore points. The minimum space required is 300MB.
On my 250GB drive, about 33GB is set aside for shadow storage. As the space
fills up, Vista deletes the oldest shadow copies. You may also Google
vssadmin. There is a lot of info about it there. If you really insist on
changing the space percentage, the 15% is set in the registry key
HKLM\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\SystemRestore\Cfg. Using
the registry editor, regedit.exe, to edit this key, in the right-hand pane,
double click the DiskPercent value and adjust if from the default setting of
15 to the percent you want. But it's a lot safer and faster to change the
size allocated, as opposed to the percent, with vssadmin.
