Understanding aging and archiving rules for items in a volume
You can set an expiration policy for a folder that affects all items in that folder. Alternatively, you can set the policy for an individual report.
An item ages and expires according to a set of rules you apply to the item itself, to the folder that contains it, or to the entire volume. The following aging and archiving rules apply to volume items:
Volume archiving rules apply to every folder in the volume, including subfolders. By default, the production volume archives files and folders once a day. The system administrator can change this default setting to specify when and how often to archive files and folders.
Folder archiving rules apply to the entire hierarchy of reports in the folder, unless subfolders also have age or date properties.
Subfolder archiving rules supersede age or date properties of folders higher in the hierarchy.
A rule for a file overrides a rule inherited from the folder that contains the file.
Folder aging and archiving properties specify the file type to which those properties apply. You can specify file types explicitly or use default values.
The aging process does not remove folders during archival, only their contents.
Archive rules determine whether the system ages dependent files along with the original files.
