Studies have shown that human error, primarily accidental file deletion or modification, causes over one-third of all data loss. For the average business, whether a small, medium, or enterprise organization, the impact of lost data is at the least an inconvenience and at the worst a critical blow that can jeopardize daily operations.
Small Business Server 2003 includes Shadow Copies of Shared Folders, a feature from Windows 2003 Server, to help prevent inadvertent loss of data. Shadow Copies of Shared Folders helps alleviate data loss by creating shadow copies of files or folders, on the volume where Users Shared Folders are located, at predetermined time intervals.
With shadow copies of shared folders, you can view the contents of network folders as they existed at times in the past. This feature may be very beneficial in the following three scenarios:
You want to recover files that were accidentally deleted. This is the network equivalent of the Recycle Bin functionality. If you accidentally delete a file, you can open an old version of the file, and then copy it to a safe location. Shadow copies of shared folders can recover files that are deleted by any mechanism, as long as the required history folder exists.
You want to recover a file after you accidentally overwrite it. Shadow copies of shared folders can be very useful in environments where you commonly create new files by opening an existing file, making modifications, and then saving the file with a new name. For example, you might open a financial-modeling spreadsheet, make modifications based upon new scenario assumptions, and then save the spreadsheet with a new name to create a new spreadsheet. The problem arises when you forget to save the file by using a new file name, so that the original work is erased. You can use a shadow copy of the shared folder to recover the previous version of the file.
You want to check different versions of the same file while you are working on the file. You could use shadow copies of shared folders during the normal work cycle when you want to determine what has changed between two versions of the same file. For example, you might want to see what your original text looked like before you spent time editing the file.
