Once a day, a backup was made to an external USB drive connected to the same server. At first glance, the backup seemed to be working; in reality, it was a system vulnerable to failure, theft, or ransomware attacks.<\/p><h3 data-start=\"416\" data-end=\"431\"><span style=\"color: #ff6500; font-size: 20px;\">Implementation<\/span><\/h3><p data-start=\"432\" data-end=\"519\">During the security audit, we proposed a simple plan that followed the principle <strong data-start=\"507\" data-end=\"516\">3-2-1<\/strong>:<\/p><ul data-start=\"520\" data-end=\"700\"><li data-start=\"520\" data-end=\"577\"><p data-start=\"522\" data-end=\"577\"><span style=\"font-weight: 600; text-align: justify;\">\u2022\u00a0<\/span>current copies made automatically to the NAS server,<\/p><\/li><li data-start=\"578\" data-end=\"630\"><p data-start=\"580\" data-end=\"630\"><span style=\"font-weight: 600; text-align: justify;\">\u2022\u00a0<\/span>an additional copy sent to the cloud daily,<\/p><\/li><li data-start=\"631\" data-end=\"700\"><p data-start=\"633\" data-end=\"700\"><span style=\"font-weight: 600; text-align: justify;\">\u2022\u00a0<\/span>once a month, rotated offline media stored outside the office.<\/p><\/li><\/ul><p data-start=\"702\" data-end=\"840\">We supplemented everything with email reports and data recovery tests so that the team could be sure that the backup would actually work if necessary.<\/p><h3 data-start=\"842\" data-end=\"853\"><span style=\"color: #ff6500; font-size: 20px;\">Effect<\/span><\/h3><p data-start=\"854\" data-end=\"1103\">Following implementation, the company gained confidence that even in the event of a server failure or ransomware attack, key files would be available within hours.

If you store your backups exclusively in the cloud, you still only have one type of media and one location. If you have issues with account access or provider policy, you could be cut off from your data.            <\/div>\n        <\/div>\n                <div class=\"elementskit-single-faq elementor-repeater-item-fac0227\">\n            <div class=\"elementskit-faq-header\">\n                <h2 class=\"elementskit-faq-title\">How much does it cost to implement 3-2-1 backup in a small business?<\/h2>\n            <\/div>\n            <div class=\"elementskit-faq-body\">\n                Costs depend primarily on data volume, backup frequency, and the software chosen. In practice, basic implementation can be achieved with a small monthly budget. Most companies choose to combine local NAS with cloud backup, offering a good compromise between price and security.            <\/div>\n        <\/div>\n                <div class=\"elementskit-single-faq elementor-repeater-item-56aed13\">\n            <div class=\"elementskit-faq-header\">\n                <h2 class=\"elementskit-faq-title\">How often should you make backups?<\/h2>\n            <\/div>\n            <div class=\"elementskit-faq-body\">\n                Ideally, daily backups are best \u2013 in that case, you&#039;ll lose a maximum of one day of work in the event of a failure. For files of particular importance (e.g., accounting, CRM systems), backups can be performed even every few hours. It&#039;s important that the schedule is consistent and automatic, and that the retention period (backup retention time) is tailored to the specific needs of the company.            <\/div>\n        <\/div>\n                <div class=\"elementskit-single-faq elementor-repeater-item-0712edb\">\n            <div class=\"elementskit-faq-header\">\n                <h2 class=\"elementskit-faq-title\">Do you really need to back up cloud services like Microsoft 365?<\/h2>\n            <\/div>\n            <div class=\"elementskit-faq-body\">\n                Yes. Many businesses assume that Microsoft or Google will handle this for them. However, vendor policies primarily cover service availability, not protection against user errors or ransomware.
