- From the Tools menu (cogwheel icon) go to Site Configuration > Archives.
- Open the Export and Import tab.
- You can edit, clone, or remove an archive by selecting the corresponding link.
When you clone an archive, the archive will be assigned a new archive ID and will be added at the bottom of the archive list (provided that the list is sorted by archive ID).
Cloning an archive is very useful if you want to retain all archive settings and only make minor modifications to an archive's search filtering, for example.
