For restore-only scenarios, the appliance works perfectly as Community Edition limitations do not affect recovery features.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Source: <a href=\"https:\/\/helpcenter.veeam.com\/docs\/vbr\/userguide\/licensing.html?ver=13\" target=\"_blank\" rel=\"noreferrer noopener\">Veeam Helpcenter<\/a><\/p>\n\n\n\n<div style=\"height:39px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:39px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-2e440c704a627e9eb92d97eed17dcb61 wp-block-paragraph\"><strong>Early Deletion Fees in Azure Cool Storage<\/strong><\/p>\n\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">A customer recently noticed Early Deletion Fees on their Azure invoice. They were using Azure Blob Storage (Cool Tier) as a storage repository for Veeam Backup &amp; Replication.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"384\" height=\"256\" src=\"https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2026\/01\/ealry-deletion-fee.png\" alt=\"\" class=\"wp-image-673\" style=\"width:277px;height:auto\" srcset=\"https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2026\/01\/ealry-deletion-fee.png 384w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2026\/01\/ealry-deletion-fee-300x200.png 300w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2026\/01\/ealry-deletion-fee-210x140.png 210w\" sizes=\"auto, (max-width: 384px) 100vw, 384px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">The root cause was a retention period configured to <strong>less than 30 days<\/strong>. Azure Cool Tier has a minimum storage duration of 30 days, defined in Microsoft\u2019s Azure Blob Storage pricing and billing terms. If data is deleted or overwritten before this period expires, Azure charges an Early Deletion Fee for the remaining days.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Although backups were working correctly in VBR, the short retention unintentionally caused additional costs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The fix was simple: increase the retention to more than 30 days. After that, the fees disappeared and costs became predictable again.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As a bonus, longer retention also improves recovery options\u2014retention below 30 days is neither cost-efficient nor a good backup strategy.<\/p>\n\n\n\n<div style=\"height:39px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:39px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-4906d50931c2cec053a57c9550b6df53 wp-block-paragraph\"><strong>All-in-One Installations and Resource Constraints<\/strong><\/p>\n\n\n\n<div style=\"height:21px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">When helping customers troubleshoot seemingly unusual backup behavior, I frequently discover that the root cause is <strong>resource constraints on the backup server<\/strong>. This problem often arises when multiple roles &#8211; Veeam Backup &amp; Replication, the database, proxies, and repositories &#8211; are all deployed on a single machine, whether on <strong>physical hardware or inside a virtual machine<\/strong>. <\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignleft size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"432\" height=\"590\" src=\"https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2026\/01\/cpu-overload.png\" alt=\"\" class=\"wp-image-674\" style=\"width:184px;height:auto\" srcset=\"https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2026\/01\/cpu-overload.png 432w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2026\/01\/cpu-overload-220x300.png 220w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2026\/01\/cpu-overload-154x210.png 154w\" sizes=\"auto, (max-width: 432px) 100vw, 432px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">Proper sizing requires accounting for all resource consumers. The <strong>operating system<\/strong> alone requires CPU and RAM, and VBR together with its <strong>database<\/strong> (SQL Express, SQL Standard, or PostgreSQL) adds further load.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Task slots assigned to repositories and proxies also consume CPU &#8211; roughly <strong>two task slots per core<\/strong> &#8211; and additional processes such as <strong>antivirus scanning, tape roles, or gateway roles<\/strong> increase the demand even more.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The risk is particularly high when VBR is installed <strong>directly on a Hyper-V host<\/strong> (which is <strong>against Veeam best practices<\/strong>), as there is no hypervisor-level resource control and conflicts can arise between VBR, the host OS, and the running VMs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Another often-overlooked factor is the choice of repository filesystem. NAS repositories without <strong>ReFS or XFS<\/strong> lack block cloning capabilities, which can otherwise significantly reduce CPU usage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Even when the system appears to perform normally, these loads can accumulate and eventually cause unpredictable behavior. Periodic sizing reviews, careful allocation of task slots, and consideration of filesystem capabilities can <strong>prevent performance bottlenecks, improve stability, and ensure smooth operations<\/strong> for both All-in-One VBR installations.<br><\/p>\n\n\n\n<div style=\"height:39px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:39px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:50%\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\">\n<div class=\"wp-block-group is-nowrap is-layout-flex wp-container-core-group-is-layout-8f761849 wp-block-group-is-layout-flex\">\n<div class=\"wp-block-media-text is-stacked-on-mobile\" style=\"grid-template-columns:17% auto\"><figure class=\"wp-block-media-text__media\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"1024\" src=\"https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/10\/Pin.png\" alt=\"\" class=\"wp-image-298 size-full\" srcset=\"https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/10\/Pin.png 1024w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/10\/Pin-300x300.png 300w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/10\/Pin-150x150.png 150w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/10\/Pin-768x768.png 768w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/10\/Pin-210x210.png 210w\" sizes=\"auto, (max-width: 980px) 100vw, 980px\" \/><\/figure><div class=\"wp-block-media-text__content\">\n<h1 class=\"wp-block-heading\"><strong>Feature of the day<\/strong><\/h1>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n<p class=\"has-vivid-cyan-blue-color has-text-color has-link-color wp-elements-bd20fbe36f11fda91cc55c4f4b5687f2 wp-block-paragraph\"><strong>Veeam Threat Hunter Automated Scanning (Version 13)<\/strong><br><\/p>\n\n\n\n<div style=\"height:17px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p class=\"wp-block-paragraph\">Over the last several releases, Veeam Backup &amp; Replication has introduced numerous malware detection features. As with any malware scanning technology, false positives can occur \u2014 and based on my experience in multiple customer environments, I have observed an increased number of false-positive alerts particularly in the area of Suspicious File Detection.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"alignright size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"160\" height=\"117\" src=\"https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/12\/threat-detection.png\" alt=\"\" class=\"wp-image-602\"\/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">With <strong>Veeam Backup &amp; Replication v13<\/strong>, administrators can now proactively validate such events by automatically triggering a <strong>signature-based scan<\/strong> when a malware event appears. This feature, also known as <strong>Veeam Threat Hunter automated scanning<\/strong>, can be enabled in the <em>Malware Detection Settings<\/em> under <em>Signature Detection<\/em>, using either Veeam Threat Hunter or a bring-your-own antivirus solution.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When enabled, Veeam automatically scans the affected restore point to confirm whether the detected anomaly represents a real threat. In addition, the new option <strong>\u201cMark backups as clean if no threats are detected by signature-based scan\u201d<\/strong> allows backups to be automatically marked as <em>Clean<\/em> if the signature scan does not confirm malware.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These enhancements significantly improve security while at the same time reducing false-positive alerts and administrative overhead \u2014 increasing confidence in both detection results and restore readiness.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Learn more here: <a href=\"https:\/\/helpcenter.veeam.com\/docs\/vbr\/userguide\/malware_detection_signature_detection.html?ver=13\" target=\"_blank\" rel=\"noreferrer noopener\">Veeam Helpcenter<\/a><\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"536\" height=\"442\" src=\"https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/12\/automated-threat-hunter.png\" alt=\"\" class=\"wp-image-601\" style=\"width:400px;height:auto\" srcset=\"https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/12\/automated-threat-hunter.png 536w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/12\/automated-threat-hunter-300x247.png 300w, https:\/\/www.lighthouse-program.com\/wp-content\/uploads\/2025\/12\/automated-threat-hunter-210x173.png 210w\" sizes=\"auto, (max-width: 536px) 100vw, 536px\" \/><\/figure>\n\n\n\n<div style=\"height:39px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<div style=\"height:39px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Thanks for reading<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">I hope you enjoyed this edition of my Lessi-Learned Newsletter.
