<h2 id="synopsis">Synopsis</h2>
<p>Removes SQL Server backups from disk.</p>
<h2 id="description">Description</h2>
<p>Removes SQL Server backups from disk.</p>
<p>Provides all of the same functionality for removing SQL backups from disk as a standard maintenance plan would.</p>
<p>As an addition you have the ability to check the Archive bit on files before deletion. This will allow you to ensure backups have been archived to your archive location before removal.</p>
<p>Also included is the ability to remove empty folders as part of this cleanup activity.</p>
<h2 id="syntax">Syntax</h2>
<pre><code>Remove-DbaBackup
    [-Path] &lt;String&gt;
    [-BackupFileExtension] &lt;String&gt;
    [-RetentionPeriod] &lt;String&gt;
    [-CheckArchiveBit]
    [-RemoveEmptyBackupFolder]
    [-EnableException]
    [-WhatIf]
    [-Confirm]
    [&lt;CommonParameters&gt;]

</code></pre>
<p> </p>
<h2 id="examples">Examples</h2>
<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; Remove-DbaBackup -Path 'C:\MSSQL\SQL Backup\' -BackupFileExtension trn -RetentionPeriod 48h
</code></pre>
<p>'*.trn' files in 'C:\MSSQL\SQL Backup' and all subdirectories that are more than 48 hours old will be removed.<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; Remove-DbaBackup -Path 'C:\MSSQL\SQL Backup\' -BackupFileExtension trn -RetentionPeriod 48h -WhatIf
</code></pre>
<p>Same as example #1, but doesn't actually remove any files. The function will instead show you what would be done.<br>
This is useful when first experimenting with using the function.<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; Remove-DbaBackup -Path 'C:\MSSQL\Backup\' -BackupFileExtension bak -RetentionPeriod 7d -CheckArchiveBit
</code></pre>
<p>'*.bak' files in 'C:\MSSQL\Backup' and all subdirectories that are more than 7 days old will be removed, but only if the files have been backed up to another location as verified by checking the <br>
Archive bit.<br></p>
<h5 id="example-4">Example:  4</h5>
<pre><code>PS C:\&gt; Remove-DbaBackup -Path 'C:\MSSQL\Backup\' -BackupFileExtension bak -RetentionPeriod 1w -RemoveEmptyBackupFolder
</code></pre>
<p>'*.bak' files in 'C:\MSSQL\Backup' and all subdirectories that are more than 1 week old will be removed. Any folders left empty will be removed as well.<br></p>
<h3 id="required-parameters">Required Parameters</h3>
<h5 id="path">-Path</h5>

<h5 id="backupfileextension">-BackupFileExtension</h5>

<h2 id="is-the-retention-value-and-must-be-an-integer-value">is the retention value and must be an integer value</h2>
<p>U signifies the units where the valid units are:<br />

w = weeks<br />
m = months<br />
Formatting Examples:<br />
'48h' = 48 hours<br />
'7d' = 7 days<br />
'4w' = 4 weeks<br />
'1m' = 1 month <br></p>

<h3 id="optional-parameters">Optional Parameters</h3>
<h5 id="checkarchivebit">-CheckArchiveBit</h5>
<p>If this switch is enabled, the filesystem Archive bit is checked before deletion. If this bit is set (which translates to &quot;it has not been backed up to another location yet&quot;, the file won't be<br />
deleted.<br></p>

<h5 id="enableexception">-EnableException</h5>
<p>By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.<br />
This avoids overwhelming you with &quot;sea of red&quot; exceptions, but is inconvenient because it basically disables advanced scripting.<br />
Using this switch turns this &quot;nice by default&quot; feature off and enables you to catch exceptions with your own try/catch.<br></p>
