We are running Small Business server 2003 / windows server 2003 with approximately 25 users on windows 2000 pro or xp pro. This morning while logging onto one user's computer I experienced a very slow logon. At the same time another user experienced a problem accessing Outlook which made him think a MS exchange or network problem was occurring.
Checking the main server event viewer I found an error entry (Event ID 25) in the System log indicating that “The shadow copies of volume D: were deleted because the shadow copy storage could not grow in time”. This is the first occurrence of this error since upgrading to SBS 2003. We had also been getting some warnings with event ID 33: “The oldest shadow copy of volume drive D: was deleted to keep disk space usage … below the user defined limit”.
I have three questions because of this: (1) why was the shadow copy deleted? Before the deletion the hard drive had approximately 9.8gb of free space. The maximum size for the shadow copy is shown as 5507mb. After deletion this hard drive had 14.8gb free space.
At what point does the operating system determine that the full shadow copy has to be deleted?
(2) what kind of load does this deletion activity create on the server? Would it be enough to slow down logins (such as cause "applying computer settings" to take a much longer time)? The deletion occurred at the same time as the user problems noted above.
(3) What are considered to be good practices in managing Shadow Copies? If keeping them is a good idea, is ensuring adequate free space on a drive the best way to avoid deletion?
Thanks for any help.
