Even FreeNAS and NAS4Free offers this feature and can be activated in its administration under <a href=\"http:\/\/wiki.nas4free.org\/doku.php?id=documentation:setup_and_user_guide:services_cifs_smb_shares&amp;s%5B%5D=recycle\" target=\"_blank\" rel=\"noopener noreferrer\">Services|CIFS\/SMB|Shares<\/a>.<\/p>\n<p>All deleted files and folders of a share are moved to this bin, physically localized on the network share. In comparison to a Windows\u2019 recycle bin the maximum size is not settable. Therefore the recycle bin is able to overflow the share.<\/p>\n<p>A cronjob and a tiny shell script can prevent this automatically.<\/p>\n<p><!--more--><\/p>\n<p>In the file system of the share in FreeNAS\/NAS4free the recycle bin is represented by the hidden folder <span class=\"codestyle\">.recycle<\/span>. All deleted files and folder of a share of <em>all<\/em> users are stored there. The following method finally erases all files and folders of an appropriate age in this folder.<\/p>\n<ol>\n<li>\n<div>Create a new file, e.g. <code>delrecycle.sh<\/code><\/div>\n<\/li>\n<li>Enter the following content to<code> delrecycle.sh<\/code>:\n<pre lang=\"bash\">#!\/bin\/sh \r\nfind \/mnt\/[MountPoint]\/.recycle\/* -atime +[Age] -exec rm -rf '{}' \\;\r\nfind \/mnt\/[MountPoint]\/.recycle\/ -depth -type d -empty -exec rmdir {} \\;<\/pre>\n<p>Adjust <code>[MountPoint]<\/code> (mount point of your share) und <code>[Age]<\/code> (age of the files in days which you want to erase) to your environment and needs.<\/p>\n<p class=\"hinweis\">Update 07\/12\/2015: As \u201cgilada\u201d posted in a German <a href=\"#comment-54548\">comment<\/a> that the script does not work correctly.\u00a0 The error <code>find: missing argument to `-exec' <\/code>appeared. To get rid of this the semicolon (;) at the end of each line has to be masked by a backslash (\\) in current UNIX versions. In my older FreeNAS-Version this was not necessary. I modified all scripts on this page. Thanks to \u201cgilada\u201d to point me to this issue.<\/p>\n<p>Example: If the name of your mount point is <span class=\"codestyle\">myshare<\/span> and you want to finally erase all files and folders which were deleted for 90 days or more, the script\u00a0 <code>delrecycle.sh<\/code> looks like:<\/p>\n<pre lang=\"bash\">#!\/bin\/sh\r\nfind \/mnt\/myshare\/.recycle\/* -atime +90 -exec rm -rf '{}' \\;\r\nfind \/mnt\/myshare\/.recycle\/ -depth -type d -empty -exec rmdir {} \\;<\/pre>\n<p>If you have more than one share you have to extend the script above. If your second mount point is called <code>myshare2<\/code>, the script is:<\/p>\n<pre lang=\"bash\">#!\/bin\/sh\r\nfind \/mnt\/myshare\/.recycle\/* -atime +90 -exec rm -rf '{}' \\;\r\nfind \/mnt\/myshare\/.recycle\/ -depth -type d -empty -exec rmdir {} \\;\r\nfind \/mnt\/myshare2\/.recycle\/* -atime +90 -exec rm -rf '{}' \\;\r\nfind \/mnt\/myshare2\/.recycle\/ -depth -type d -empty -exec rmdir {} \\;<\/pre>\n<\/li>\n<li>Upload <code>delrecycle.sh<\/code> to your share.<\/li>\n<li>Create a cronjob (System|Advanced|Cron) with <span class=\"codestyle\">root<\/span>\u2013 privileges, which calls the command:\n<pre lang=\"bash\">sh \/path\/to\/MountPoint\/delrecycle.sh<\/pre>\n<p>daily. Following the example above, the command should look like:<\/p>\n<pre lang=\"bash\">sh \/mnt\/myshare\/delrecycle.sh<\/pre>\n<div id=\"attachment_1981\" style=\"width: 310px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/blog.hani-ibrahim.de\/wp-content\/uploads\/freenas-cron-en.png\" data-rel=\"lightbox-gallery-pIqrNthx\" data-rl_title=\"Cronjob in FreeNAS\" data-rl_caption=\"\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-1981\" class=\"size-medium wp-image-1981\" title=\"Cronjob in FreeNAS\" src=\"https:\/\/blog.hani-ibrahim.de\/wp-content\/uploads\/freenas-cron-en-300x208.png\" alt=\"Cronjob in FreeNAS\" width=\"300\" height=\"208\" srcset=\"https:\/\/blog.hani-ibrahim.de\/wp-content\/uploads\/freenas-cron-en-300x208.png 300w, https:\/\/blog.hani-ibrahim.de\/wp-content\/uploads\/freenas-cron-en.png 900w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\"><\/a><p id=\"caption-attachment-1981\" class=\"wp-caption-text\">Cronjob in FreeNAS<\/p><\/div>\n<p>In the screenshoot above the script is called at every first and fifteenth day of a month at midnight.<\/p>\n<\/li>\n<\/ol>\n<h3 id=\"h0\">Peculiarities of Samba\u2019s recycle bin<\/h3>\n<p>Because Samba\u2019s recycle bin behaves different to the Desktop ones on Windows, Mac or Linux the article <a title=\"Peculiarities of Samba\u2019s recycle bin\" href=\"https:\/\/blog.hani-ibrahim.de\/samba-recycle-bin.html\">Peculiarities of Samba\u2019s recycle bin<\/a> may help.<\/p>\n<p><\/p><\/body>","protected":false},"excerpt":{"rendered":"<div class=\"shariff shariff-align-left shariff-widget-align-left\" data-services=\"facebook\" data-url=\"https:\/\/blog.hani-ibrahim.de\/en\/automatic-purge-samba-recycle-bin.html\" data-timestamp=\"1602095499\" data-backendurl=\"https:\/\/blog.hani-ibrahim.de\/en\/wp-json\/shariff\/v1\/share_counts?\"><ul class=\"shariff-buttons theme-round orientation-horizontal buttonsize-small\"><li class=\"shariff-button facebook shariff-nocustomcolor\" style=\"background-color:#4273c8;border-radius:50%\"><a href=\"https:\/\/www.facebook.com\/sharer\/sharer.php?u=https%3A%2F%2Fblog.hani-ibrahim.de%2Fen%2Fautomatic-purge-samba-recycle-bin.html\" title=\"Share on Facebook\" aria-label=\"Share on Facebook\" role=\"button\" rel=\"nofollow\" class=\"shariff-link\" style=\";border-radius:50%;
