A collision can occur even if the files are restored or retrieved to an emptydirectory. For example, files abcdef~1.doc and abcdefghijk.doc might originally haveexisted in the directory as abcdefghijk.doc and abcdef~2.doc. During the restore, ifabcdefghijk.doc is restored first, it is assigned a short name of abcdef~1.doc by theWindows operating system. When you restore abcdef~1.doc, the duplicate file namesituation occurs.Tivoli Storage Manager handles these situations based on the value of the replaceoption. Use the replace option to specify whether to overwrite an existing file, or toprompt you for your selection when you restore or retrieve files.If a file name collision occurs, you can do any of the following:v Restore or retrieve the file with the short file name to a different location.v Stop the restore or retrieve and change the name of the existing file.v Disable short file name support on Windows.v Do not use file names, such as abcdef~1.doc, that would conflict with the shortfile naming convention.Related reference“Replace” on page 441Universal Naming Convention names restoreUsing a Universal Naming Convention (UNC) name permits you to restore specificshared files to a separate file space.
