<h2 id="synopsis">Synopsis</h2>
<p>Get date/time for last known backups of databases.</p>
<h2 id="description">Description</h2>
<p>Retrieves and compares the date/time for the last known backups, as well as the creation date/time for the database.</p>
<p>Default output includes columns Server, Database, LastFullBackup, LastDiffBackup, LastLogBackup.</p>
<h2 id="syntax">Syntax</h2>
<pre><code>Get-DbaLastBackup
    [-SqlInstance] &lt;DbaInstanceParameter[]&gt;
    [[-SqlCredential] &lt;PSCredential&gt;]

<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; Get-DbaLastBackup -SqlInstance ServerA\sql987
</code></pre>
<p>Returns a custom object with Server name, Database name, and the date the last time backups were performed.<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; Get-DbaLastBackup -SqlInstance ServerA\sql987 | Select-Object *
</code></pre>
<p>Returns a custom object with Server name, Database name, and the date the last time backups were performed, and also recoverymodel and calculations on how long ago backups were taken and what the <br>
status is.<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; Get-DbaLastBackup -SqlInstance ServerA\sql987 | Select-Object * | Out-Gridview
</code></pre>
<p>Returns a gridview displaying ComputerName, InstanceName, SqlInstance, Database, RecoveryModel, LastFullBackup, LastDiffBackup, LastLogBackup, SinceFull, SinceDiff, SinceLog, <br>
LastFullBackupIsCopyOnly, LastDiffBackupIsCopyOnly, LastLogBackupIsCopyOnly, DatabaseCreated, DaysSinceDbCreated, Status<br></p>
<h5 id="example-4">Example:  4</h5>
<pre><code>PS C:\&gt; $MyInstances | Get-DbaLastBackup | Where-Object -FilterScript { $_.LastFullBackup.Date -lt (Get-Date).AddDays(-3) } | Format-Table -Property SqlInstance, Database, LastFullBackup
</code></pre>
<p>Returns all databases on the given instances without a full backup in the last three days.<br>
Note that the property LastFullBackup is a custom object, with the subproperty Date of type datetime and therefore suitable for comparison with dates.<br></p>
<h5 id="example-5">Example:  5</h5>
<pre><code>PS C:\&gt; Get-DbaLastBackup -SqlInstance ServerA\sql987 | Where-Object { $_.LastFullBackupIsCopyOnly -eq $true }
</code></pre>
<p>Filters for the databases that had a copy_only full backup done as the last backup.<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>
