Shadow Copies (MCP Series)

Shadow Copies provide point-in-time copies of data saved on shared folders. Shadow copies are not a replacement for a backup but can protect against files that are accidently deleted or overwritten. You can also use shadow copies to compare different versions of files. Shadow copies can be enabled and configured by using the Shadow Copies tab of the Local Disk Properties box, or by using the Computer Management Console. By default, 64 shadow copies are kept unless otherwise specified. A minimum spare space of 100mb (300mb?) is required to create shadow copies. By default Windows 2003 Server will make two shadow copies per day. Shadow Copies can be viewed on the server at any time, but clients require special software installed on their computers to view shadow copies.
