I can&#8217;t say any of the results surprised me. Every single one of the top 5 comes from the &#8220;Basics&#8221; series.<\/p>\n<p>Number 5, on that list, was <a title=\"Listing files in a backup\" href=\"https:\/\/nsrd.info\/blog\/2009\/01\/27\/basics-listing-files-in-a-backup\/\" target=\"_blank\">Basics \u2013 Listing Files in a backup<\/a>. There&#8217;s a lot of people out there who want to know how to use nsrinfo in general, and specifically want to know about pulling file lists for savesets. Net result? I think it would be greatly beneficial if in NMC users could double-click on browsable savesets and get a complete listing of files therein.<\/p>\n<p>Number 4 was <a title=\"Basics - mminfo, savetime and greater than\/less than\" href=\"https:\/\/nsrd.info\/blog\/2009\/02\/01\/basics-mminfo-savetime\/\" target=\"_blank\">Basics \u2013 mminfo, savetime and greater than\/less than<\/a>. Now, I&#8217;m not going to pretend that every person who visited that article was looking for details about how greater than and less than works in mminfo in relation to savetimes, though I suspect a reasonable percentage of people new to mminfo found that interesting. My take on it is that it proves there&#8217;s not really enough documentation about mminfo, and that mminfo needs some expansion. My personal preference? Having a full SQL-like query engine for mminfo would greatly expand the options available to NetWorker administrators.<\/p>\n<p>Number 3 on the list is <a title=\"Basics \u2013\u00a0Changing saveset browse\/retention times\" href=\"https:\/\/nsrd.info\/blog\/2009\/02\/16\/basics-changing-saveset-browseretention-times\/\" target=\"_blank\">Basics \u2013 Changing saveset browse\/retention times<\/a>. As regularly as possible I try to check the search strings that have brought people to my blog (as recorded by wordpress), and I can practically guarantee that every day there are multiple combinations to do with savesets, browse and retention times. Sometimes those combinations reference nsrmm, sometimes they don&#8217;t. Clearly, extending saveset browse\/retention times in NetWorker needs to be more manageable from within the GUI as a bare minimum. I&#8217;ll get to the command line in a moment.<\/p>\n<p>Moving on to number 2, we have something that I get search results for <em>every day without fail<\/em>. That&#8217;s <a title=\"Basics - Fixing NSR Peer Information Errors\" href=\"https:\/\/nsrd.info\/blog\/2009\/02\/23\/basics-fixing-nsr-peer-information-errors\/\" target=\"_blank\">Basics \u2013 Fixing &#8220;NSR Peer information&#8221; errors<\/a>. It&#8217;s actually a reasonably simple error to fix, but sometimes finding the information about it is a bit like the old needle-in-a-haystack. I&#8217;m hoping that the posting on it has helped quite a few sites to clear out the warnings\/errors in their logs and reduce the amount of clutter being reported.<\/p>\n<p>Finally, for number 1, a topic I&#8217;m completely unsurprised to see at the top, we have <a title=\"Basics \u2013\u00a0Parallelism in NetWorker\" href=\"https:\/\/nsrd.info\/blog\/2009\/02\/17\/basics-parallelism-in-networker\/\" target=\"_blank\">Basics \u2013 Parallelism in NetWorker<\/a>. Not because it&#8217;s difficult, but because there&#8217;s no absolute rules, parallelism is a topic in NetWorker that many administrators, regardless of length of time with the product, find challenging at times. Set too low, and backups may overrun. Set too high, and device contention, client slow-downs, recovery performance issues, etc., may come into play. Tuning parallelism in NetWorker has to take a <em>lot<\/em> into account.<\/p>\n<p>The content of this list suggests a few things to me:<\/p>\n<ul>\n<li>None of this information is out of reach in the product manuals, <em>but<\/em>, since the product manuals are (necessarily) lengthy, it is logistically is out of reach for a lot of users who don&#8217;t have time to read lengthy manuals.<\/li>\n<li>EMC product management could take a few tips from the top 5 articles on my blog \u2013 I think they represent areas that could be improved within <em>usability<\/em> of the product. While parallelism is not something that can &#8220;solved&#8221; by changes within the GUI (it is, by necessity, complex), other options, such as improving mminfo search, making saveset contents more accessible within the GUI, etc., <em>are<\/em> readily fixable.<\/li>\n<li>It seems there might be scope for a &#8220;Getting Started with NetWorker&#8221; style manual. I think a traditional book would (a) be too expensive and (b) be unsuitable. This is the sort of information that people want readily to hand on their desktops.<\/li>\n<\/ul>\n<p>On the last point, I&#8217;m interested in writing such a manual. I obviously have <a title=\"Enterprise Systems Backup and Recovery: A Corporate Insurance Policy\" href=\"http:\/\/www.amazon.com\/Enterprise-Systems-Backup-Recovery-Corporate\/dp\/1420076396\/ref=sr_1_1?ie=UTF8&amp;s=books&amp;qid=1236819150&amp;sr=8-1\" target=\"_blank\">some experience with writing<\/a> \u2013 but more so than just the book, over the years I&#8217;ve written literally <em>thousands<\/em> of pages of NetWorker instructions as part of professional services documentation, training courses, etc.<\/p>\n<p>So here&#8217;s a question \u2013 would people be interested in say, an eBook along the lines of &#8220;Getting Started with NetWorker&#8221; that gives basic operational and instruction usage so that rather than having to wade through the (close to 1000+) pages of the official documentation they had something shorter, and geared towards day to day operation?<\/p>\n<p>Let me know what you think.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>So this morning I was looking through the stats for this blog, and I generated the list of most popular&hellip;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[6,13,16],"tags":[351,410,531,542,594,650,662,718,861,923,930],"class_list":["post-706","post","type-post","status-publish","format-standard","hentry","category-basics","category-general-thoughts","category-networker","tag-ebook","tag-greater-than","tag-less-than","tag-listing-files","tag-mminfo","tag-nsr-peer-information","tag-nsrinfo","tag-parallelism","tag-savetime","tag-ssbrowse","tag-ssretent"],"aioseo_notices":[],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_shortlink":"https:\/\/wp.me\/pKpIN-bo","jetpack_sharing_enabled":true,"jetpack_likes_enabled":true,"_links":{"self":[{"href":"https:\/\/nsrd.info\/blog\/wp-json\/wp\/v2\/posts\/706","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nsrd.info\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nsrd.info\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nsrd.info\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/nsrd.info\/blog\/wp-json\/wp\/v2\/comments?post=706"}],"version-history":[{"count":0,"href":"https:\/\/nsrd.info\/blog\/wp-json\/wp\/v2\/posts\/706\/revisions"}],"wp:attachment":[{"href":"https:\/\/nsrd.info\/blog\/wp-json\/wp\/v2\/media?parent=706"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nsrd.info\/blog\/wp-json\/wp\/v2\/categories?post=706"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nsrd.info\/blog\/wp-json\/wp\/v2\/tags?post=706"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
