About archiving Windows Server 2012 and later deduplicated files with FSA
Windows Server 2012 and later include a file-level data deduplication mechanism.
By default, FSA archives the deduplicated files. Options on the Archiving Rules tab and the Shortcuts tab of the Enterprise Vault FSA Volume policies and Folder policies enable you to turn off archiving or shortcut creation for Windows deduplicated files, if you want.
If you decide to turn off archiving or shortcut creation for the deduplicated files, bear in mind that Windows does not deduplicate files immediately. Enterprise Vault applies the deduplicated file policy settings to a file only if the file is in a deduplicated state when Enterprise Vault assesses it for archiving or for shortcut creation. The order of events can lead to different archiving outcomes. For example, suppose that you set the policy options for deduplicated files as follows:
[ Selected ] | Do not archive deduplicated files on Windows Server 2012 and later. |
[ Unselected ] | Do not create shortcuts for deduplicated files on Windows Server 2012 and later. |
The following scenario may then occur:
Enterprise Vault archives a file before Windows has deduplicated it. Since the file is not in a deduplicated state when Enterprise Vault assesses it, the policy setting for archiving the deduplicated files is not considered.
While the file awaits shortcut creation on the file server, Windows deduplicates it.
Enterprise Vault then creates a shortcut for the file, adhering to the policy setting for creating shortcuts for deduplicated files.
The same policy settings can have different results if the deduplicated file is modified before Enterprise Vault creates a shortcut for it. Once Windows has deduplicated the file, Enterprise Vault does not rearchive it, because of the policy setting for deduplicated files. Enterprise Vault does not create a shortcut for the modified file, because for shortcut creation Enterprise Vault requires the latest version of the file to be in the archive.
