You can configure your system to either automatically save
a version of an item each time it is published, or allow users to
select when to save a version of an item. You can restore items individually,
or choose to restore a set of items within a library that either have
the same label or were versioned at, or before, a specified date and
time.
Item level version control
- If automatic versioning is enabled, a version is saved each time
you save an item, or if the item is participating in a workflow, each
time the item's state changes to published. You cannot save versions
of draft items.
- If manual versioning is enabled, users with editor access or higher
can manually save versions of published items. You can restore a version
by viewing an item's version history and selecting a version to restore.
- Any hierarchical relationships to other items are not saved. For
example, if you save a version of a site area that has child site
areas and you delete the child site areas, the child site areas will
not be restored if you restore the parent site area.
- If you have links to external resources within an item, a copy
of the external item is not saved when a version is created. If you
delete the external resource, you cannot use the web Content Management
version feature to restore the external resource.
Item names: An item name is independent
of version control. For example, changing the name of version 4 will
also change the name of all versions of that item.
Library level version control
- You cannot choose to save a version of an entire library. Only
those items that have had versions saved using item level version
controls are saved within a library.
- You can restore a set of items from within a library that either
have the same label or were versioned at, or before, a specified date
and time.
You can apply a label to the most recent set of saved versions
in a library at any time and then restore all the items with the same
label at a later date.
Note: Labels that you apply to versions
are not syndicated to subscribers.
Clearing version history
The clear versions
tool can be used to clear version histories from items. It is configurable
and can be used to clear versions within a specific date range, for
specific item-types or libraries, or to keep only a certain number
of most recent versions.
