<h2 id="synopsis">Synopsis</h2>
<p>Scan backup files and creates a set, compatible with Restore-DbaDatabase</p>
<h2 id="description">Description</h2>
<p>Upon being passed a list of potential backups files this command will scan the files, select those that contain SQL Server<br />
backup sets. It will then filter those files down to a set</p>
<p>The function defaults to working on a remote instance. This means that all paths passed in must be relative to the remote instance.<br />
XpDirTree will be used to perform the file scans</p>
<p>Various means can be used to pass in a list of files to be considered. The default is to non recursively scan the folder<br />
passed in.</p>

<h2 id="examples">Examples</h2>
<p> </p>
<h5 id="example-1">Example:  1</h5>
<pre><code>PS C:\&gt; Get-DbaBackupInformation -SqlInstance Server1 -Path c:\backups\ -DirectoryRecurse
</code></pre>
<p>Will use the Server1 instance to recursively read all backup files under c:\backups, and return a dbatools BackupHistory object<br></p>
<h5 id="example-2">Example:  2</h5>
<pre><code>PS C:\&gt; Get-DbaBackupInformation -SqlInstance Server1 -Path c:\backups\ -DirectoryRecurse -ExportPath c:\store\BackupHistory.xml
PS C:\&gt; robocopy c:\store\ \\remoteMachine\C$\store\ BackupHistory.xml
PS C:\&gt; Get-DbaBackupInformation -Import -Path  c:\store\BackupHistory.xml | Restore-DbaDatabase -SqlInstance Server2 -TrustDbBackupHistory
</code></pre>
<p>This example creates backup history output from server1 and copies the file to the remote machine in order to preserve backup history. It is then used to restore the databases onto server2.<br></p>
<h5 id="example-3">Example:  3</h5>
<pre><code>PS C:\&gt; Get-DbaBackupInformation -SqlInstance Server1 -Path c:\backups\ -DirectoryRecurse -ExportPath C:\store\BackupHistory.xml -PassThru | Restore-DbaDatabase -SqlInstance Server2
</code></pre>
<p>-TrustDbBackupHistory<br>
In this example we gather backup information, export it to an xml file, and then pass it on through to Restore-DbaDatabase.<br>
This allows us to repeat the restore without having to scan all the backup files again<br></p>
<h5 id="example-4">Example:  4</h5>
<pre><code>PS C:\&gt; Get-ChildItem c:\backups\ -recurse -files | Where-Object {$_.extension -in ('.bak','.trn') -and $_.LastWriteTime -gt (get-date).AddMonths(-1)} | Get-DbaBackupInformation -SqlInstance Server1
</code></pre>
<p>-ExportPath C:\backupHistory.xml<br>
This lets you keep a record of all backup history from the last month on hand to speed up refreshes<br></p>
<h5 id="example-5">Example:  5</h5>
<pre><code>PS C:\&gt; $Backups = Get-DbaBackupInformation -SqlInstance Server1 -Path \\network\backups
PS C:\&gt; $Backups += Get-DbaBackupInformation -SqlInstance Server2 -NoXpDirTree -Path c:\backups
</code></pre>
<p>Scan the unc folder \network\backups with Server1, and then scan the C:\backups folder on<br>
Server2 not using xp_dirtree, adding the results to the first set.<br></p>
<h5 id="example-6">Example:  6</h5>
<pre><code>PS C:\&gt; $Backups = Get-DbaBackupInformation -SqlInstance Server1 -Path \\network\backups -MaintenanceSolution
</code></pre>
<p>When MaintenanceSolution is indicated we know we are dealing with the output from Ola Hallengren backup scripts. So we make sure that a FULL folder exists in the first level of Path, if not we <br>
shortcut scanning all the files as we have nothing to work with<br></p>
<h5 id="example-7">Example:  7</h5>
<pre><code>PS C:\&gt; $Backups = Get-DbaBackupInformation -SqlInstance Server1 -Path \\network\backups -MaintenanceSolution -IgnoreLogBackup
</code></pre>
<p>As we know we are dealing with an Ola Hallengren style backup folder from the MaintenanceSolution switch, when IgnoreLogBackup is also included we can ignore the LOG folder to skip any scanning of <br>
log backups. Note this also means they WON'T be restored<br></p>
<h3 id="required-parameters">Required Parameters</h3>
<h5 id="path">-Path</h5>
<p>Path to SQL Server backup files.<br />
Paths passed in as strings will be scanned using the desired method, default is a non recursive folder scan<br />
Accepts multiple paths separated by ','<br />
Or it can consist of FileInfo objects, such as the output of Get-ChildItem or Get-Item. This allows you to work with<br />
your own file structures as needed <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>
