To ensure the longevity of a document on a computer, one should perform a backup operation. This involves creating a duplicate copy of the document and storing it in a separate location, such as an external hard drive or cloud storage. This way, if the original document becomes corrupted or lost, the backup copy can be used to restore it. An "enregistrement" refers to simply saving the document without creating a backup copy, so it does not guarantee the document's longevity. Copying the document in the same folder or compressing it also do not provide the same level of protection as a backup.
