En air-gapped backup er isoleret fra netv\u00e6rket, enten fysisk ved at fjerne drevet eller afbryde portene, eller digitalt ved at blokere netv\u00e6rkstrafik til den. En uforanderlig backup kan ikke \u00e6ndres eller slettes, f\u00f8r dens opbevaringsperiode udl\u00f8ber, men uforanderlighed kr\u00e6ver ikke, at den er offline. Den kan stadig v\u00e6re tilg\u00e6ngelig via netv\u00e6rket.<\/p>\n<p>Veeam peger tydeligt p\u00e5 svagheden ved hver af dem. Fysisk logistik g\u00f8r gendannelse fra en air gap langsommere. Uforanderlige backups forbliver tilg\u00e6ngelige over netv\u00e6rket, hvilket udg\u00f8r en risiko, n\u00e5r de omkringliggende kontroller er svage.<\/p>\n<p>Uforanderlighed forhindrer, at en backup bliver \u00e6ndret. En air gap forhindrer, at den kan n\u00e5s.
