Oracle solves our problems with ZDLRA.<\/p>\n<p>Imagine a machine that backs up your database with a zero data loss mission for you and does this with very high performance.<\/p>\n<p>Now we can look at the technical specifications of ZDLRA.<\/p>\n<p>Oracle ZDLRA is a product that can grow in hardware and horizontally.<\/p>\n<p>When we examine the template below, the chassis called Base Rack can backup \/ restore 5TB of data in an hour while operating at a capacity of 94TB.<\/p>\n<p>When you switch to a Full Rack chassis, the Capacity reaches a figure of 580TB, while 7TB of data is processed in an hour.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.cozumpark.com\/wp-content\/uploads\/2020\/02\/image-73-1024x519.png\" \/><\/p>\n<h3>Architectural design:<\/h3>\n<p>Oracle database becomes part of the ecosystem. ZDLRA only backs up changed data after the first full backup. This backup process uses a technology called RMAN Delta push and completes it with zero data loss. Due to the system architecture, it can transfer backups to different areas.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.cozumpark.com\/wp-content\/uploads\/2020\/02\/Screenshot_2-4-1024x537.jpg\" \/><\/p>\n<p>Incremental backups taken after full backup are always kept ready for restoration depending on parameter or capacity.<\/p>\n<p>All these processes can be monitored by Oracle Enterprise Cloud Control.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.cozumpark.com\/wp-content\/uploads\/2020\/02\/Screenshot_3-1-1024x508.jpg\" \/><\/p>\n<p>While accessing our ZDRLA main database, it uses RMAN Deltra push feature as well as DELTA STORE technology. Deltra Store ZDRLA is like the brain of the software.<\/p>\n<p>It validates the modified data blocks flowing through the Delta Store and serves as storage by compressing them and adding them to the indexes.<\/p>\n<p>These modified blocks form the basis of the database on ZDRLA. This structure provides 5 times performance and space savings compared to traditional backups.<\/p>\n<p>When we look at the other features of Oracle ZDRLA, we see that it offers policy-based protection. It can transfer the backups on ZDRLA to Tape or ZDRLA at a different point.<\/p>\n<p>The Gold, Silver and Bronze policies, which come ready-made, provide convenience and can be customized at the same time.<\/p>\n<p>Examining the example image below, we can see different policies for different environments. This also shows that we can apply different policies to each database.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" src=\"https:\/\/www.cozumpark.com\/wp-content\/uploads\/2020\/02\/Screenshot_4-1024x524.jpg\" \/><\/p>\n<h3>Software features of Oracle ZDRLA:<\/h3>\n<p>Real Time Redo Transport<\/p>\n<p>ZDRLA Management of remote locations<\/p>\n<p>Autonomous tape archiving<\/p>\n<p>End-to-end data validation, accuracy of database backups<\/p>\n<p>Incremental backup strategy<\/p>\n<p>Management of backups by ZDLRA<\/p>\n<p>Cloud Scale Architecture<\/p>\n<p>Unified management and control with RMAN and Oracle Enterprise Manager<\/p>\n<p>We have finished the first part of our introductory ZDRLA article, you can view the video recording prepared for ZDRLA from the link below.<\/p>\n<pre class=\"lang:default decode:true\">https:\/\/youtu.be\/szlfbBXoXYs?list=PLWNBSK4H-NWqEDsUt6PP0jelcgJMG6pLq<\/pre>\n<div class=\"pvc_clear\"><\/div>\n<p id=\"pvc_stats_54412\" class=\"pvc_stats all  \" data-element-id=\"54412\" style=\"\"><i class=\"pvc-stats-icon medium\" aria-hidden=\"true\"><svg aria-hidden=\"true\" focusable=\"false\" data-prefix=\"far\" data-icon=\"chart-bar\" role=\"img\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 512 512\" class=\"svg-inline--fa fa-chart-bar fa-w-16 fa-2x\"><path fill=\"currentColor\" d=\"M396.8 352h22.4c6.4 0 12.8-6.4 12.8-12.8V108.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v230.4c0 6.4 6.4 12.8 12.8 12.8zm-192 0h22.4c6.4 0 12.8-6.4 12.8-12.8V140.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v198.4c0 6.4 6.4 12.8 12.8 12.8zm96 0h22.4c6.4 0 12.8-6.4 12.8-12.8V204.8c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v134.4c0 6.4 6.4 12.8 12.8 12.8zM496 400H48V80c0-8.84-7.16-16-16-16H16C7.16 64 0 71.16 0 80v336c0 17.67 14.33 32 32 32h464c8.84 0 16-7.16 16-16v-16c0-8.84-7.16-16-16-16zm-387.2-48h22.4c6.4 0 12.8-6.4 12.8-12.8v-70.4c0-6.4-6.4-12.8-12.8-12.8h-22.4c-6.4 0-12.8 6.4-12.8 12.8v70.4c0 6.4 6.4 12.8 12.8 12.8z\" class=\"\"><\/path><\/svg><\/i> <img loading=\"lazy\" decoding=\"async\" width=\"16\" height=\"16\" alt=\"Loading\" src=\"https:\/\/dbtut.com\/wp-content\/plugins\/page-views-count\/ajax-loader-2x.gif\" border=0 \/><\/p>\n<div class=\"pvc_clear\"><\/div>\n","protected":false},"excerpt":{"rendered":"<p>In today&#8217;s article, I will be explain about the Zero Data Loss Recovery Appliance (ZDLRA) product developed by Oracle.
