Saving All SharePoint Solutions in a SharePoint On-Premises Farm

In SharePoint on-premises environments, managing solutions can be cumbersome, especially when multiple solutions are deployed across the farm. The PowerShell script below allows administrators to save all solutions (.wsp files) from the farm, ensuring they have backups for each solution:

# PowerShell Script to Save All Solutions in a SharePoint On-Premises Farm
$solutions = Get-SPSolution
$savePath = "C:\Backup\SharePointSolutions\"

if (-Not (Test-Path -Path $savePath)) {
    New-Item -ItemType Directory -Path $savePath
}

foreach ($solution in $solutions) {
    $fileName = $solution.SolutionFile.Name
    $solution.SolutionFile.SaveAs("$savePath\$fileName")
    Write-Host "Saved: $fileName"
}

How It Works:

• Get-SPSolution: Retrieves all deployed solutions in the SharePoint farm.
• SaveAs: Saves the .wsp file to the specified directory ($savePath).
• The script creates a backup directory if it doesn’t already exist.

Steps:

1. Preparation: Set the backup path.
2. Execution: Run the script in SharePoint Management Shell to backup all solutions.

Why This Matters:

This script is crucial for ensuring you have a full backup of all deployed solutions, providing safety in case of future migrations, custom solution updates, or farm restorations.

Customizing the Script:

• Modify $savePath to your desired directory.
• Add logging to track solution saves.

This simple yet powerful script gives SharePoint administrators peace of mind by efficiently backing up all SharePoint solutions in an on-premises environment. It is essential to run this script before any major changes or updates to your farm to prevent data loss and simplify rollback processes.

Additional Notes:

Make sure you have appropriate permissions and are using the SharePoint Management Shell when running this script.
