De Nakivo-back-ups werden verwijderd, terwijl de gegevens van de virtuele machines op het volume werden versleuteld.<\/p>\n<p>Het IT-team van de klant voerde meerdere dagen lang herstelprogramma's uit op het volume, zonder succes. Ze kopieerden ook 15 TB aan productiegegevens naar dezelfde opslag die de verwijderde back-ups eerder hadden ingenomen. Dat proces overschreef delen van de verwijderde back-upgegevens.<\/p>\n<p>DriveSavers maakte images van de schijven en herbouwde handmatig ontbrekende BTRFS-mappinginformatie om toegang te krijgen tot back-upgegevens die het volume al had vrijgegeven. Het herstel op de prioritaire databaseserver bereikte, alleen al vanuit de back-uprepository, 99,4 procent. Door de onversleutelde delen van de productie-virtuele schijven te combineren met de back-upgegevens, steeg het slagingspercentage tot 99,91 procent.<\/p>\n<p>Zonder die 15 TB aan overschreven data zou het een volledig herstel zijn geweest.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><div id=\"case-study-solution\" class=\"vc_section wpex-relative\"><div class=\"vc_row wpb_row vc_row-fluid vc_row-o-content-middle vc_row-flex wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><div class=\"vc_empty_space\"   style=\"height: 40px\"><span class=\"vc_empty_space_inner\"><\/span><\/div><style>.vcex-heading.vcex_6a925edc445ba{color:#3e3d3e;font-size:35px;font-weight:400;}@media (max-width:1024px){.vcex-heading.vcex_6a925edc445ba{font-size:25px;}}@media (max-width:959px){.vcex-heading.vcex_6a925edc445ba{font-size:25px;}}@media (max-width:767px){.vcex-heading.vcex_6a925edc445ba{font-size:25px;}}@media (max-width:479px){.vcex-heading.vcex_6a925edc445ba{font-size:25px;}}<\/style><div class=\"vcex-heading vcex-heading-plain vcex-module wpex-heading wpex-text-2xl wpex-div vcex_6a925edc445ba translation-block\"><span class=\"vcex-heading-inner wpex-inline-block\">Onveranderlijk, air-gapped, en <strong><span style=\"color: #e31f26\">waar elk van beide ophoudt<\/span><\/strong><\/span><\/div><div class=\"vc_empty_space\"   style=\"height: 10px\"><span class=\"vc_empty_space_inner\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid vc_row-o-content-middle vc_row-flex wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div style=\"color:#6f737e;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p>Onveranderlijkheid en air gapping worden vaak in \u00e9\u00e9n adem genoemd, maar vervullen elk een andere functie.<\/p>\n<p class=\"translation-block\">Veeam maakt <a href=\"https:\/\/www.veeam.com\/blog\/air-gap-vs-immutable-backups-key-differences.html\" target=\"_blank\" rel=\"noopener\">dit onderscheid<\/a> duidelijk. Een air-gapped back-up is ge\u00efsoleerd van het netwerk, ofwel fysiek door de schijf te verwijderen of de poorten los te koppelen, ofwel digitaal door netwerkverkeer ernaartoe te blokkeren. Een onveranderlijke back-up kan niet worden gewijzigd of verwijderd totdat de bewaartermijn is verstreken, maar onveranderlijkheid vereist niet dat deze offline is. Ze kan bereikbaar blijven via het netwerk.<\/p>\n<p>Veeam benoemt duidelijk de zwakte van elke aanpak. Fysieke logistiek vertraagt het herstel vanuit een air gap. Onveranderlijke back-ups blijven toegankelijk via het netwerk, wat een risico vormt wanneer de bijbehorende controles zwak zijn.<\/p>\n<p>Onveranderlijkheid voorkomt dat een back-up wordt gewijzigd. Een air gap voorkomt dat deze kan worden bereikt. Een gecompromitteerde beheerlaag kan geen invloed uitoefenen op een back-up die zij niet kan bereiken.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid vc_row-o-content-middle vc_row-flex wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><div class=\"vc_empty_space\"   style=\"height: 40px\"><span class=\"vc_empty_space_inner\"><\/span><\/div><style>.vcex-heading.vcex_6a925edc45b2a{color:#3e3d3e;font-size:35px;font-weight:400;}@media (max-width:1024px){.vcex-heading.vcex_6a925edc45b2a{font-size:25px;}}@media (max-width:959px){.vcex-heading.vcex_6a925edc45b2a{font-size:25px;}}@media (max-width:767px){.vcex-heading.vcex_6a925edc45b2a{font-size:25px;}}@media (max-width:479px){.vcex-heading.vcex_6a925edc45b2a{font-size:25px;}}<\/style><div class=\"vcex-heading vcex-heading-plain vcex-module wpex-heading wpex-text-2xl wpex-div vcex_6a925edc45b2a translation-block\"><span class=\"vcex-heading-inner wpex-inline-block\">Wat u <strong><span style=\"color: #e31f26\">nu moet controleren<\/span><\/strong><\/span><\/div><div class=\"vc_empty_space\"   style=\"height: 10px\"><span class=\"vc_empty_space_inner\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid vc_row-o-content-middle vc_row-flex wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div style=\"color:#6f737e;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p>Stel uw leverancier \u00e9\u00e9n vraag: kan een beheerder met volledige rechten de onveranderlijkheidsinstelling op dit platform overschrijven?<\/p>\n<p>Het antwoord hangt af van hoe onveranderlijkheid is ge\u00efmplementeerd.

Wanneer een decryptietool al is uitgevoerd en bestanden beschadigd heeft achtergelaten, kunnen we mogelijk de daaruit voortvloeiende schade herstellen. Wanneer een virtuele schijf gedeeltelijk versleuteld is, gebruikt DriveSavers zijn tools en technieken om gegevens uit niet-getroffen gebieden te identificeren en te herstellen. We herstellen ook oudere of niet-getroffen versies van de gegevens, ook uit copy-on-write-systemen, en we doorzoeken alternatieve bronnen zoals tapes en cloudresources.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div><\/div><\/div><div class=\"vc_section vc_custom_1772464080847 vc_section-o-content-middle vc_section-flex wpex-vc-full-width-section wpex-vc-full-width-section--centered wpex-relative wpex-vc_section-has-fill wpex-vc-reset-negative-margin\"><div class=\"vc_row wpb_row vc_row-fluid vc_row-o-content-middle vc_row-flex wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\"><div class=\"vc_empty_space\"   style=\"height: 40px\"><span class=\"vc_empty_space_inner\"><\/span><\/div><style>.vcex-heading.vcex_6a925edc4c17c{color:#3e3d3e;font-size:35px;font-weight:400;}@media (max-width:1024px){.vcex-heading.vcex_6a925edc4c17c{font-size:25px;}}@media (max-width:959px){.vcex-heading.vcex_6a925edc4c17c{font-size:25px;}}@media (max-width:767px){.vcex-heading.vcex_6a925edc4c17c{font-size:25px;}}@media (max-width:479px){.vcex-heading.vcex_6a925edc4c17c{font-size:25px;}}<\/style><div class=\"vcex-heading vcex-heading-plain vcex-module wpex-heading wpex-text-2xl wpex-div vcex_6a925edc4c17c translation-block\"><span class=\"vcex-heading-inner wpex-inline-block\">Uw herstelopties <strong><span style=\"color: #e31f26\">beschermen<\/span><\/strong><\/span><\/div><div class=\"vc_empty_space\"   style=\"height: 10px\"><span class=\"vc_empty_space_inner\"><\/span><\/div><\/div><\/div><\/div><\/div><div class=\"vc_row wpb_row vc_row-fluid vc_row-o-content-middle vc_row-flex wpex-relative no-bottom-margins\"><div class=\"wpb_column vc_column_container vc_col-sm-12\"><div class=\"vc_column-inner\"><div class=\"wpb_wrapper\">\n\t<div style=\"color:#6f737e;font-size:18px;\" class=\"wpb_text_column has-custom-color wpex-child-inherit-color wpb_content_element\" >\n\t\t<div class=\"wpb_wrapper\">\n\t\t\t<p>Koppel getroffen apparaten zo snel mogelijk los van het netwerk.

Tijd is cruciaal bij een ransomware-respons: vaststellen of gegevens herstelbaar zijn kan uren of dagen duren, terwijl beslissingen over bedrijfscontinu\u00efteit en losgeldonderhandelingen mogelijk veel eerder moeten worden genomen.<\/p>\n<p>Wie de beslissingen ook neemt, doet dat onder druk, en er zou al een vertrouwde dataherstelaanbieder in het reactieplan moeten zijn opgenomen.
