Optimizing offline storage by sharing items

Some HSM software products do not support the OFFLINE file attribute to indicate that a file has been moved to HSM secondary storage. In such cases, the Storage service assumes that a file is offline when a specific number of days have elapsed since the file was last modified.

To specify the number of days before the Storage service assumes that a file is offline, you use the OfflineDays registry value. The default value is 0, which means that the Storage service assumes that items are always online.

If several users share an item, the Storage service archives another copy of the item. All copies of a shared item are usually archived at the same time so that only one is archived.

To change the offline setting

  1. Edit the registry on the computer that is running the Enterprise Vault Storage service.

  2. Edit, or if necessary add, the following DWORD value:

    HKEY_LOCAL_MACHINE 
     \SOFTWARE 
      \KVS 
       \Enterprise Vault 
    	\OfflineDays
    
  3. Set the value to the number of days that items stay online. The default value is 0, which stops the Storage service using the secondary offline status checking. If you set OfflineDays to 0, then the offline status is determined by the OFFLINE file attribute setting.

    The new setting is used immediately.
