noun
conservation
kahn-ser-VAY-shuhn/ˌkɑːnsərˈveɪʃn/
The preservation of something against loss or depletion.
The specialist's careful conservation protects the weathered painting from further deterioration.

Etymology
Servare means keeping watch or maintaining, with con- perhaps strengthening that idea. Conservation originally described keeping something sound and in good condition—the same protective purpose now applied to natural resources and cultural objects.
In context
conservation is the maintenance of the works of arts and their protection from future damage and restoration is restoring them once damage has already happened
