The main idea is: For each link saved in the database, a backup link that contains a snapshot of the page at the time the link was registered should be automatically generated and stored.
Automatically obtaining a link with the snapshot of a particular site would be especially useful to avoid losing useful or historical knowledge when a site permanently ceases to exist.
Description
The main idea is: For each link saved in the database, a backup link that contains a snapshot of the page at the time the link was registered should be automatically generated and stored.
To achieve this goal, the suggestion is to use services such as the Wayback machine from https://archive.org/ and/or http://archive.today/
Rationale
Automatically obtaining a link with the snapshot of a particular site would be especially useful to avoid losing useful or historical knowledge when a site permanently ceases to exist.
