The use of open-source tools like Restic and the ZFS file system, combined with the orchestration power of Kubernetes, resulted in a highly reliable and efficient backup system suitable for virtual machines backed by block storage.<\/p><p>The same approach was later adapted for the efficient backup of databases, demonstrating its versatility and scalability.<\/p><p><strong>Additional links:<\/strong><\/p><div class=\"vlp-link-container vlp-layout-quick wp-block-visual-link-preview-link\"><a href=\"https:\/\/itnext.io\/backup-storage-for-thousands-of-virtual-machines-using-free-tools-b3909004bef2\" class=\"vlp-link\" title=\"Backup storage for thousands of virtual machines using free tools\" rel=\"nofollow\" target=\"_blank\"><\/a><div class=\"vlp-layout-zone-side\"><div class=\"vlp-block-2 vlp-link-image\"><img decoding=\"async\" src=\"https:\/\/miro.medium.com\/v2\/resize:fit:1200\/0*A6SRoMPAkAf-RnRB.png\" style=\"max-width: 150px; max-height: 150px\" \/><\/div><\/div><div class=\"vlp-layout-zone-main\"><div class=\"vlp-block-0 vlp-link-title\">Backup storage for thousands of virtual machines using free tools<\/div><div class=\"vlp-block-1 vlp-link-summary\">We needed a backup solution to handle thousands of backups each week and do it as fast and efficiently as possible.<\/div><\/div><\/div><div class=\"vlp-link-container vlp-layout-quick wp-block-visual-link-preview-link\"><a href=\"https:\/\/kvaps.medium.com\/4bc1e8f083c1\" class=\"vlp-link\" title=\"Restic: Effective Backup from Stdin\" rel=\"nofollow\" target=\"_blank\"><\/a><div class=\"vlp-layout-zone-side\"><div class=\"vlp-block-2 vlp-link-image\"><img decoding=\"async\" src=\"https:\/\/miro.medium.com\/v2\/resize:fit:720\/0*uJ7As9uTvB-gvQLe.png\" style=\"max-width: 150px; max-height: 150px\" \/><\/div><\/div><div class=\"vlp-layout-zone-main\"><div class=\"vlp-block-0 vlp-link-title\">Restic: Effective Backup from Stdin<\/div><div class=\"vlp-block-1 vlp-link-summary\">A ready-made solution for setting up effective backup from Stdin, with deduplication and automatic cleaning of the repository from old copie<\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Development of a large-scale backup system for virtual machines.
