It&#039;s a standalone instance that can also be run virtually. Backup storage is mounted to it, for example via iSCSI or NFS. Backups are then performed in this mounted storage. Of course, local storage on the Backup Server can also be used. In Proxmox VE, the Backup Server is then integrated as a separate storage type.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-877f905 elementor-widget elementor-widget-image\" data-id=\"877f905\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t<figure class=\"wp-caption\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"768\" height=\"441\" src=\"https:\/\/ciit-software.com\/wp-content\/uploads\/2025\/04\/Figure3_ProxmoxBackupServer-768x441.jpg\" class=\"attachment-medium_large size-medium_large wp-image-8351\" alt=\"\" srcset=\"https:\/\/ciit-software.com\/wp-content\/uploads\/2025\/04\/Figure3_ProxmoxBackupServer-768x441.jpg 768w, https:\/\/ciit-software.com\/wp-content\/uploads\/2025\/04\/Figure3_ProxmoxBackupServer-300x172.jpg 300w, https:\/\/ciit-software.com\/wp-content\/uploads\/2025\/04\/Figure3_ProxmoxBackupServer-1024x588.jpg 1024w, https:\/\/ciit-software.com\/wp-content\/uploads\/2025\/04\/Figure3_ProxmoxBackupServer-1536x881.jpg 1536w, https:\/\/ciit-software.com\/wp-content\/uploads\/2025\/04\/Figure3_ProxmoxBackupServer-2048x1175.jpg 2048w, https:\/\/ciit-software.com\/wp-content\/uploads\/2025\/04\/Figure3_ProxmoxBackupServer-18x10.jpg 18w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/>\t\t\t\t\t\t\t\t\t\t\t<figcaption class=\"widget-image-caption wp-caption-text\">Proxmox Backup Server<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-b54cb2e elementor-widget elementor-widget-text-editor\" data-id=\"b54cb2e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Backups to the backup server are automatically incremental and deduplicative. Because the backup is based on snapshots, there is no interruption to the VM&#039;s operation.\u00a0<\/p><p>The backup server can automatically replicate between two storage locations to achieve backup redundancy. It also features automated jobs for pruning, garbage collection, and backup verification. All these functions can be configured in granular detail via the web interface. Finally, it&#039;s also possible to store encrypted data on the backup server.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-bbdf848 elementor-widget elementor-widget-heading\" data-id=\"bbdf848\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Backups in the cloud<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-d3c3c1a elementor-widget elementor-widget-text-editor\" data-id=\"d3c3c1a\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Our backups are redundantly stored in two different buildings. This is achieved using the replication function of the backup server. Additionally, we create backups in the cloud to cover the event of a disaster in which both local backups are corrupted. While it would be possible to mount Amazon S3 or Google Cloud Buckets to the backup server for cloud backups, the backup would fail because these storage types do not support certain file operations used by the backup server.<\/p>\n<p>The more practical way to perform backups in the cloud is different: You install an instance of the backup server in the cloud with directly connected storage behind it. Then you integrate this cloud backup server into the local Proxmox cluster. This is an excellent and extremely reliable solution. There are now also specialized providers, such as the Dutch company [name of provider missing in original text]. <a href=\"https:\/\/www.tuxis.nl\/\">Tuxis<\/a>. This provider offers pre-configured Proxmox backup servers that are available within minutes. When backing up to the cloud, the encryption supported by Proxmox backup servers is essential.&nbsp;<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3424b79 elementor-widget elementor-widget-heading\" data-id=\"3424b79\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Pitfalls of migration<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3ebeebe elementor-widget elementor-widget-text-editor\" data-id=\"3ebeebe\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>For performance reasons, we forego centralized, shared storage to implement high availability. This means that VMs and data reside directly on the respective host on which the machine is running. This approach leverages the superior performance of the NVMe-based hardware RAID arrays used \u2013 incomparable to a storage system connected via cables.<\/p><p>One drawback is failover. To implement fast failover, continuous live replication of the virtual machines is necessary. Here, a limitation of Proxmox causes us problems: replication is only possible if ZFS is used as the underlying file system. This wouldn&#039;t be a problem in itself, but: ZFS cannot be used on a hardware RAID array. This means that disk operation would have to be switched to JBOD mode, and a ZFS array would have to be used based on that.<\/p><p>Since we have no prior experience with ZFS arrays and reports indicate that ZFS arrays have performance disadvantages compared to hardware arrays, we have decided to refrain from this change for the time being.<\/p><p>The functionality for VM replication therefore remains unavailable to us for the time being. We hope for further development of the replication feature in Proxmox so that LVM-based storage is also supported.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2ea6b3e elementor-widget elementor-widget-heading\" data-id=\"2ea6b3e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Summary<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4b5d842 elementor-widget elementor-widget-text-editor\" data-id=\"4b5d842\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Proxmox offers outstanding functionality and stability at a very low cost.
