\/><\/figure><\/div>\n\n\n\n<p>In the discussion, we\u2019ll consider the first full backup, and a full recovery. On the recovery side, this means:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li>Recovering from local backup \u2013 a full bare metal recovery, which copies all data from your backup device to your target drives<\/li><li>Recovering from cloud backup \u2013 which downloads your entire backup from the cloud, back to a local device<\/li><\/ol>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Local backups (disk to disk) performance factors<\/strong><\/h2>\n\n\n\n<p>The disk to disk portion of the backup in BackupAssist ER is generally very fast.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Speed of backup device \u2013 level of influence: high<\/h3>\n\n\n\n<p>For most people, the write speed of the backup device is going to be the limiting factor in the D2D drive image.<\/p>\n\n\n\n<p>Most people will use a backup device that is slower than the main drives in the server. Here are some bottlenecks to performance.<\/p>\n\n\n\n<p><strong>Direct Attached Storage<\/strong><\/p>\n\n\n\n<p>Interface limitations:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>SATA \u2013 theoretical limit of 6 Gbps (750 MB\/s)<\/li><li>USB 3.0 \u2013 theoretical limit of 5 Gbps (625 MB\/s)<\/li><li>USB 3.1 \u2013 theoretical limit of 10 Gbps (1250 MB\/s)<\/li><li>USB 3.2 \u2013 theoretical limit of 20 Gbps (2500 MB\/s)<\/li><\/ul>\n\n\n\n<p>Storage device limitations:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>HDD \u2013 typical manufacturer\u2019s quoted speeds: 227 MB\/s (<a href=\"https:\/\/documents.westerndigital.com\/content\/dam\/doc-library\/en_us\/assets\/public\/western-digital\/product\/internal-drives\/wd-black-hdd\/data-sheet-wd-black-pc-hard-drives-2879-771434.pdf\">WD black<\/a>), 180 MB\/s (<a href=\"https:\/\/documents.westerndigital.com\/content\/dam\/doc-library\/en_us\/assets\/public\/western-digital\/product\/internal-drives\/wd-black-hdd\/data-sheet-wd-black-pc-hard-drives-2879-771434.pdf\">WD Red<\/a>)<ul><li>If a hard disk already contains data, the level of file fragmentation on the disk becomes extremely relevant.<\/li><\/ul><\/li><\/ul>\n\n\n\n<ul class=\"wp-block-list\"><li>SATA SSD \u2013 typical manufacturer\u2019s quoted speed: 550 MB\/s sustained read <em>&amp; <\/em>write<ul><li>Note: in our testing, we found that many SSDs are unable to maintain the manufacturer\u2019s sustained write speed for long.

In that case, the bottleneck will be the source drives.<\/p>\n\n\n\n<p>In addition to the bottlenecks listed above, the source drives are influenced by:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>RAID controller<\/li><li>Level of data fragmentation on the drives<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Cloud backups (disk to cloud)<\/strong><\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Speed of network connection to cloud storage \u2013 level of influence: high<\/h3>\n\n\n\n<p>By far, the biggest influence on speed is the speed of your network connection to the cloud storage provider. For most on-premise situations, that\u2019s limited by the speed of the service provided by your Internet Service Provider.<\/p>\n\n\n\n<p>For example, if you have a 100\/20 connection, it\u2019s highly likely that you will get close to 20 Mbps of throughput for your backup, and 100 Mbps for your recovery. In an experiment we ran in Jan 2021, we can see the various backup and recovery speeds from an on-premise machine to 3 different public clouds.<\/p>\n\n\n\n<p>Speed of internet connection, as tested by speedtest.net:<\/p>\n\n\n\n<div class=\"wp-block-image is-style-default\"><figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"504\" height=\"96\" src=\"https:\/\/www.backupassist.com\/app\/uploads\/sites\/3\/2021\/01\/data-1.png\" alt=\"\" class=\"wp-image-16996\" srcset=\"https:\/\/www.backupassist.com\/app\/uploads\/sites\/3\/2021\/01\/data-1.png 504w, https:\/\/www.backupassist.com\/app\/uploads\/sites\/3\/2021\/01\/data-1-300x57.png 300w\" sizes=\"auto, (max-width: 504px) 100vw, 504px\" \/><\/figure><\/div>\n\n\n\n<p>Average speed of backup and recovery:<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-regular\">\n  <table style=\"border-collapse:collapse;border:none;\">\n    <thead>\n      <tr>\n        <th style=\"width:30%;border-collapse:collapse;border:none;background:#008ECE;color:white;\"><strong>Operation<\/strong><\/th>\n        <th style=\"width:30%;border-collapse:collapse;border:none;border-left:1px solid white;background:#008ECE;color:white;text-align:center;\"><strong>Wasabi<\/strong><\/th>\n        <th style=\"width:20%;border-collapse:collapse;border:none;border-left:1px solid white;background:#008ECE;color:white;text-align:center;\"><strong>Azure<\/strong><\/th>\n        <th style=\"width:20%;border-collapse:collapse;border:none;border-left:1px solid white;background:#008ECE;color:white;text-align:center;\"><strong>AWS<\/strong><\/th>\n      <\/tr>\n    <\/thead>\n    <tbody>\n      <tr>\n        <td style=\"border-collapse:collapse;border:none;border-left:1px solid white;background:#d1dff1;color:#282561;\">Backup<\/td>\n        <td style=\"border-collapse:collapse;border:none;border-left:1px solid white;background:#d1dff1;color:#282561;text-align:center;\">10.6 Mbps<\/td>\n        <td style=\"border-collapse:collapse;border:none;border-left:1px solid white;background:#d1dff1;color:#282561;text-align:center;\">10.0 Mbps<\/td>\n        <td style=\"border-collapse:collapse;border:none;border-left:1px solid white;background:#d1dff1;color:#282561;text-align:center;\">10.5 Mbps<\/td>\n      <\/tr>\n      <tr>\n        <td style=\"border-collapse:collapse;border:none;border-left:1px solid white;background:#a9c7e7;color:#282561;color:#282561;\">Recovery<\/td>\n        <td style=\"border-collapse:collapse;border:none;border-left:1px solid white;background:#a9c7e7;color:#282561;color:#282561;text-align:center;\">82.2 Mbps<\/td>\n        <td style=\"border-collapse:collapse;border:none;border-left:1px solid white;background:#a9c7e7;color:#282561;color:#282561;text-align:center;\">79.7 Mbps<\/td>\n        <td style=\"border-collapse:collapse;border:none;border-left:1px solid white;background:#a9c7e7;color:#282561;color:#282561;text-align:center;\">80.2 Mbps<\/td>\n      <\/tr>\n    <\/tbody>\n  <\/table>\n<\/figure>\n\n\n\n<p>Note: We\u2019ll share our testing data in a future blog post.<\/p>\n\n\n\n<p>The factors affecting how close your Internet connection gets to its saturation point are:<\/p>\n\n\n\n<ol class=\"wp-block-list\" type=\"1\"><li>The latency between your machine and the cloud service<\/li><li>The sustained transfer rate between your machine and the cloud service<\/li><\/ol>\n\n\n\n<p>Latency is important because it affects how much \u201cwait time\u201d there is in between actual data transfers. This means you can expect poorer performance if you are backing up across large distances \u2013 such as across countries.<\/p>\n\n\n\n<p>And as shown in the table above, the sustained transfer rate presents the theoretical upper limit for overall average upload and download speed.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Having many small files in the backup \u2013 level of influence: high<\/h3>\n\n\n\n<p>Let\u2019s take two scenarios \u2013 if you have 10 GB of data in one file, versus 10 GB of data in 100,000 files, which will back up and recover faster?<\/p>\n\n\n\n<p>The answer, hands down, is the former \u2013 the single file scenario. Let\u2019s see why\u2026<\/p>\n\n\n\n<p>It\u2019s all to do with the \u201cchunking\u201d algorithm in BackupAssist\u2019s cloud engine. It will take each file and split it into deduplicated chunks, with average size of 2 MB. But if a file is under 2 MB in size, then the entire file is stored as one chunk.<\/p>\n\n\n\n<p>In our two scenarios:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Single file scenario \u2013 the file is split into (on average) 5,000 chunks of 2 MB each<\/li><li>Many file scenario \u2013 the files are stored as 100,000 chunks of (on average) 100 KB each.<\/li><\/ul>\n\n\n\n<p>This means that in our first scenario, BackupAssist will issue 5,000 requests to the cloud storage, but in the second scenario, there will be 100,000 requests. That\u2019s 20 times more!<\/p>\n\n\n\n<p>Each request to the server takes time, and the effect is very noticeable if there is a high latency between your machine and the cloud service.<\/p>\n\n\n\n<p>We do try to mitigate this problem by having many concurrent connections open to the cloud service, but there is no avoiding the fact that many requests to the cloud server will slow things down.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Speed of your cloud storage service \u2013 level of influence: medium<\/h3>\n\n\n\n<p>In our experimental testing, we tested the speed of various cloud services for backup and recovery, and discovered that the speed of the cloud service does make a difference.<\/p>\n\n\n\n<p>In one experiment that shows the differences the best, we see about a 10% difference between the fastest and slowest cloud on recovery, but a whopping 76% difference on the backup.<\/p>\n\n\n\n<figure class=\"wp-block-table is-style-regular\">\n  <table

cores \u2013 level of influence: medium<\/h3>\n\n\n\n<p>Assuming that your network connection and the speed of your cloud service are not significant bottlenecks, then the number of CPU threads \/ cores does affect your backup and recovery speed.<\/p>\n\n\n\n<p>In our <a href=\"https:\/\/www.backupassist.com\/blog\/the-effect-of-cpu-on-cloud-backup-and-recovery-speeds-in-backupassist-er\"><strong>detailed experiments with different CPU threads \/ cores<\/strong><\/a> we saw a roughly 30% improvement when doubling the number of CPU threads from 8 to 16. But going beyond 16 threads will not yield a significant performance benefit.<\/p>\n\n\n\n<p>The reasons for this are discussed in that blog article.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Speed of the drive to which you download the cloud backup \u2013 level of influence: low<\/h3>\n\n\n\n<p>The final factor we\u2019ll discuss today concerns the recovery \u2013 and that\u2019s the disk to which you\u2019re recovering. When you download a complete backup from the cloud, your target disk can make a difference.<\/p>\n\n\n\n<p>Let\u2019s assume for now that you have a fast network, fast cloud service, and a 16 thread CPU.<\/p>\n\n\n\n<p>If you recover to a <strong>hard drive instead of an SSD<\/strong>, you\u2019ll experience a slowdown, especially if you have huge files in your backup. (And we regard anything over 20GB to be a huge file&#8230; and the bigger the file, the more potential slowdown you might experience.)<\/p>\n\n\n\n<p>The reason for this is that BackupAssist has to download chunks and then reassemble them to recreate the original files. The catch is that we cannot predict in advance what order these chunks will arrive\u2026 in fact, most of the time they arrive out of order. Thus, we often have to write chunks to temp files on disk, and then rewrite them \u201cin place\u201d in the final destination when contiguous chunks become available.<\/p>\n\n\n\n<p>This can cause a considerable amount of Disk I\/O as data gets written to, read from, and rewritten to the same disk.<\/p>\n\n\n\n<p>On SSDs, this effect is barely noticeable, but on spinning hard drives, it can result in a slowdown.<\/p>\n\n\n\n<p>We\u2019ll publish results on this effect shortly. For most situations, the speed of the target disk is not a significant factor, but it can show up if there are no other bottlenecks in the system and your backups contain huge files.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Conclusions<\/strong><\/h2>\n\n\n\n<p>BackupAssist ER can provide extremely high performance backup and recovery in environments without significant bottlenecks.<\/p>\n\n\n\n<p>However, every system will have limitations \u2013 many stemming from underlying budgetary or practical considerations.<\/p>\n\n\n\n<p>Understanding the bottlenecks can give you an understanding of what to expect from BackupAssist ER in your environment, and a guide on how to get the best recovery performance with the resources at your disposal.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We often hear from clients that the feature set of BackupAssist ER makes it a cost-effective alternative to DRaaS solutions \u2013 with key features being able to cut downtime to just a few minutes by virtualizing the recovery on-premise, and to be able to fully recover from the cloud copy of the backup.<\/p>\n","protected":false},"author":17,"featured_media":17018,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[757],"tags":[],"class_list":["post-16981","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-cyber-resilience"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.9 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>What affects the speed of backups and recoveries in BackupAssist ER?
