|
|
<p>The recycle bin is a storage of deleted entries from the server. This allows
|
|
recovery from mistakes for a period of time.</p>
|
|
<blockquote>
|
|
<p><strong>WARNING:</strong> The recycle bin is a best effort - when recovering in some cases
|
|
not everything can be "put back" the way it was. Be sure to check your entries
|
|
are valid once they have been revived.</p>
|
|
</blockquote>
|
|
<h2 id="where-is-the-recycle-bin"><a class="header" href="#where-is-the-recycle-bin">Where is the Recycle Bin?</a></h2>
|
|
<p>The recycle bin is stored as part of your main database - it is included in all
|
|
backups and restores, just like any other data. It is also replicated between
|
|
all servers.</p>
|
|
<h2 id="how-do-things-get-into-the-recycle-bin"><a class="header" href="#how-do-things-get-into-the-recycle-bin">How do things get into the Recycle Bin?</a></h2>
|
|
<p>Any delete operation of an entry will cause it to be sent to the recycle bin. No
|
|
configuration or specification is required.</p>
|
|
<h2 id="how-long-do-items-stay-in-the-recycle-bin"><a class="header" href="#how-long-do-items-stay-in-the-recycle-bin">How long do items stay in the Recycle Bin?</a></h2>
|
|
<p>Currently they stay up to 1 week before they are removed.</p>
|
|
<h2 id="managing-the-recycle-bin"><a class="header" href="#managing-the-recycle-bin">Managing the Recycle Bin</a></h2>
|
|
<p>You can display all items in the Recycle Bin with:</p>
|
|
<pre><code>kanidm recycle_bin list --name admin
|
|
</code></pre>
|
|
<p>You can show a single items with:</p>
|
|
<pre><code>kanidm recycle_bin get --name admin <id>
|
|
</code></pre>
|
|
<p>An entry can be revived with:</p>
|
|
<pre><code>kanidm recycle_bin revive --name admin <id>
|
|
</code></pre>
|
|
<h2 id="edge-cases"><a class="header" href="#edge-cases">Edge cases</a></h2>
|
|
<p>The recycle bin is a best effort to restore your data - there are some cases where
|
|
the revived entries may not be the same as their were when they were deleted. This
|
|
generally revolves around reference types such as group membership.</p>
|
|
<p>An example of this is the following steps:</p>
|
|
<pre><code>add user1
|
|
add group1
|
|
add user1 as member of group1
|
|
delete user1
|
|
delete group1
|
|
revive user1
|
|
revive group1
|
|
</code></pre>
|
|
<p>In this series of steps, due to the way that referential integrity is implemented, the
|
|
membership of user1 in group1 would be lost in this process. To explain why:</p>
|
|
<pre><code>add user1
|
|
add group1
|
|
add user1 as member of group1 // refint between the two established, and memberof added
|
|
delete user1 // group1 removes member user1 from refint
|
|
delete group1 // user1 now removes memberof group1 from refint
|
|
revive user1 // re-add groups based on directmemberof (empty set)
|
|
revive group1 // no members
|
|
</code></pre>
|
|
<p>This issue could be looked at again in the future, but for now we think that deletes of
|
|
groups is rare - we expect recycle bin to save you in "opps" moments, and in a majority
|
|
of cases you may delete a group or a user and then restore them. To handle this series
|
|
of steps requires extra code complexity in how we flag operations. For more,
|
|
see <a href="https://github.com/kanidm/kanidm/issues/177">This issue on github</a>.</p>
