I've created a powershell script to do this. You have to connect to SQL server which has the SSRS database. It is compressing all the files into a zip file.
Add-Type -AssemblyName "System.IO.Compression.Filesystem"
$dataSource = "SQLSERVER"
$user = "sa"
$pass = "sqlpassword"
$database = "ReportServer"
$connectionString = "Server=$dataSource;uid=$user; pwd=$pass;Database=$database;Integrated Security=False;"
$tempfolder = "$env:TEMP\Reports"
$zipfile = $PSScriptRoot + '\reports.zip'
$connection = New-Object System.Data.SqlClient.SqlConnection
$connection.ConnectionString = $connectionString
$connection.Open()
$allreports = $connection.CreateCommand()
$allreports.CommandText = "SELECT ItemID, Path, CASE WHEN Type = 2 THEN '.rdl' ELSE 'rds' END AS Ext FROM Catalog WHERE Type IN(2,5)"
$result = $allreports.ExecuteReader()
$reportable = new-object "System.Data.DataTable"
$reportable.Load($result)
[int]$objects = $reportable.Rows.Count
foreach ($report in $reportable) {
$cmd = $connection.CreateCommand()
$cmd.CommandText = "SELECT CAST(CAST(Content AS VARBINARY(MAX)) AS XML) FROM Catalog WHERE ItemID = '" + $report[0] + "'"
$xmldata = [string]$cmd.ExecuteScalar()
$filename = $tempfolder + $report["Path"].Replace('/', '\') + $report["Ext"]
New-Item $filename -Force | Out-Null
Set-Content -Path ($filename) -Value $xmldata -Force
Write-Host "$($objects.ToString()).$($report["Path"])"
$objects -= 1
}
Write-Host "Compressing to zip file..."
if (Test-Path $zipfile) {
Remove-Item $zipfile
}
[IO.Compression.Zipfile]::CreateFromDirectory($tempfolder, $zipfile)
Write-Host "Removing temporarly data"
Remove-Item -LiteralPath $tempfolder -Force -Recurse
Invoke-Item $zipfile
