These periods may have 100% overlap, or they may be distinctly different. For instance, the &#8220;standard&#8221; browse\/retention policies chosen by NetWorker when you create a new client are:<\/p>\n<ul>\n<li>Browse period \u2013 1 month<\/li>\n<li>Retention period \u2013 1 year<\/li>\n<\/ul>\n<p>A common mistake people make with NetWorker is to assume that the retention period starts when the browse period finishes; in actual fact, the retention and browse period start at the same time, but the browse period can finish <em>before<\/em> the retention period. So using that standard setting as an example, the saveset is browsable for the first 1 month of the 12 months that it is retained \u2013 it is <em>not<\/em> the case that the saveset is browsable for 1 month, then retained for another 12.<\/p>\n<p>Once data is no longer within the retention period, <em>and there are no backups that depend on it still within the retention period<\/em>, data is considered to be recyclable.<\/p>\n<p>When data is recyclable:<\/p>\n<ul>\n<li>If it is on tape:\n<ul>\n<li>The data will remain available until the media is <em>recycled<\/em>. This will only happen once all the backups on the media is also recyclable, <em>and<\/em> either the administrator manually recycles the media or NetWorker re-uses it.<\/li>\n<\/ul>\n<\/li>\n<li>If it is on a disk backup unit (ADV_FILE) device:\n<ul>\n<li>The data will be erased from the disk backup unit the next time a volume clean operation is run, or nsrim is run (either as a overnight standard event by NetWorker, or manually via <em>nsrim -X<\/em>).<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>This isn&#8217;t the &#8220;whole picture&#8221; for data lifecycle within NetWorker, but it is a good brief overview to give you an idea of how data is managed within the environment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Within NetWorker, data (savesets) can go through several stages in its lifecycle.
