Altid aktuelt: Sp\u00f8rgsm\u00e5let om sikkerhedskopiering af data vedr\u00f8rer b\u00e5de privatpersoner og virksomheder. I den private sf\u00e6re er datatab yderst irriterende; for virksomheder er konsekvenserne langt mere vidtr\u00e6kkende. Et alternativ til lokale sikkerhedskopier er brug af en cloud-server. Her anvendes moderne teknologier, og sikkerhedsforanstaltningerne er normalt meget h\u00f8jere end i dine egne fire v\u00e6gge. Men hvad er de faktiske muligheder for cloud backup?<\/p>\n

Fordele ved cloud-backup<\/h2>\n

Hardwaredefekter er ofte uforudsigelige. Dette g\u00e6lder ikke kun for arbejdsmilj\u00f8et, men ogs\u00e5 for sikkerhedskopieringsmedier. Ud over slitage er str\u00f8msvigt, vandskade, brand, lynnedslag, tyveri eller tab ikke ubetydelige risici. S\u00e5danne risici minimeres ved sikkerhedskopiering p\u00e5 en cloudserver, fordi datacentre hos velrenommerede udbydere er udstyret i overensstemmelse hermed og ogs\u00e5 forberedt p\u00e5 uforudsigelige situationer.<\/p>\n

Mange tjenesteudbydere tilbyder tilsvarende software til at automatisere sikkerhedskopieringen. I den private sektor og for mindre store datam\u00e6ngder er gratis tjenester som Dropbox en god mulighed. Du er dog selv ansvarlig for sikkerheden af din sikkerhedskopi ved at tildele en passende adgangskode og beskytte den. Overf\u00f8rslen kan ogs\u00e5 v\u00e6re forbundet med risici. Andre tjenesteudbydere som Acronis, Symantec eller Mailstore arbejder derimod ikke med virtuelle datamapper og direkte adgangsmuligheder. De tilbyder betydeligt mere lagervolumen, ideelt set krypteret overf\u00f8rsel og opkr\u00e6ver et overkommeligt gebyr for det.<\/p>\n

Software til online backup af data<\/h2>\n

Sikkerheden ved online lagringstjenester kan optimeres ved hj\u00e6lp af software som Areca Backup eller Duplicati. Den arbejder sammen med de f\u00e6lles tjenester, som Data<\/a> F\u00f8r de overf\u00f8res til Dropbox eller Google, skal de dog K\u00f8rsel<\/a> krypteret og komprimeret. Det er ogs\u00e5 muligt at bruge standardprotokoller som FTP, WebDAV eller SSH. Uautoriseret adgang under overf\u00f8rslen og til de data, der er sikret online, vanskeligg\u00f8res ved hj\u00e6lp af softwaren.<\/p>\n

Komplet backup af systemet<\/h2>\n

S\u00e6rlige softwarel\u00f8sninger, der er designet til professionel brug, s\u00e5som Carbonite Server Backup fra Mailstore, er langt mere sofistikerede. Her anvendes moderne kryptering, sikkerhedskopieringen finder sted under drift, og sikkerhedskopieringen kan finde sted lokalt s\u00e5vel som i udbyderens datacenter eller parallelt. Krypteringen udf\u00f8res ved hj\u00e6lp af AES 128-bit eller valgfrit 256-bit, hvorved processerne kan tilpasses til dine specifikke krav. Sikkerhedskopiering som et image med s\u00e5kaldt bare metal recovery muligg\u00f8r \u00f8jeblikkelig datagendannelse - om n\u00f8dvendigt, selv p\u00e5 nyligt implementeret hardware.<\/p>\n

Afh\u00e6ngigt af den valgte pakke er typen og antallet af mulige systembackups af fysiske og virtuelle milj\u00f8er forskellige. En v\u00e6sentlig fordel ved softwaren med cloud-forbindelse via et tysk datacenter er muligheden for at sikkerhedskopiere ikke kun f\u00f8lsomme data, men ogs\u00e5 komplette applikationer og databaser. Kompatibilitet med mailstore-arkiver fra samme udbyder er naturligvis ogs\u00e5 garanteret, s\u00e5 vigtig kommunikation ogs\u00e5 bevares. De automatiske processer p\u00e5virker ikke den l\u00f8bende drift, og udbyderen sikrer naturligvis de n\u00f8dvendige databeskyttelsesforanstaltninger. Omkostninger<\/a> afviger fra det valgte omfang af tjenesterne.<\/p>\n

Konklusion - Cloud-backup som en fornuftig foranstaltning<\/h2>\n

N\u00e5r f\u00f8rst dataene er g\u00e5et tabt, er konsekvenserne n\u00e6sten ustoppelige, og den \u00f8konomiske skade kan v\u00e6re langt st\u00f8rre end investeringen i passende software. Gennemt\u00e6nkte og konfigurerbare automatiseringsprocesser, krypteringsforanstaltninger og online lagring er ideelle for virksomheder, der \u00f8nsker at sikre den st\u00f8rst mulige sikkerhed med en lille indsats. Som privat bruger er s\u00e5danne naturligvis for st\u00e6rke - her kan kombinationen af en online lagringstjeneste med backup-software m\u00e5ske v\u00e6re tilstr\u00e6kkeligt. Grundl\u00e6ggende g\u00e6lder dog f\u00f8lgende: Det er altid mere fornuftigt og effektivt at bruge en cloud-backup end udelukkende at bruge lokal backup.<\/p>","protected":false},"excerpt":{"rendered":"
