Can you write a Windows script to check if a backup made with restic is ok?

The answer:

Verifying Restic Backups on Windows with PowerShell

Understanding the Script:

This PowerShell script checks the integrity of the latest Restic backup. It assumes you have Restic installed and configured on your system.

Key points:

  • Restic Path: Ensure the $resticPath variable points to the correct location of your Restic executable.
  • Repository Path: Replace 'C:\path\to\your\repository' with the actual path to your Restic repository.
  • Password: For security reasons, avoid hardcoding the password directly in the script. Consider using environment variables or secure storage methods.
  • Error Handling: The script includes basic error handling, but you might want to expand it for specific error scenarios.
PowerShell
# Define variables
$resticPath = "$env:ProgramFiles\Restic\restic.exe"
$repositoryPath = 'C:\path\to\your\repository'
$password = "your_password"  # Replace with a secure way to store the password

# Check if Restic is installed
if (!(Test-Path $resticPath)) {
    Write-Warning "Restic is not installed. Please install Restic before running this script."
    return
}

# Function to execute Restic commands
function Execute-ResticCommand {
    param(
        [string]$command
    )

    try {
        & $resticPath --repo "$repositoryPath" --password-file "$password" $command
    } catch {
        Write-Warning "Error executing Restic command: $_"
    }
}

# List the latest backup
$latestBackup = Execute-ResticCommand "list last --json" | ConvertFrom-Json | Select-Object -First 1

# Check the integrity of the latest backup
Execute-ResticCommand "check $($latestBackup.id)"

Write-Host "Backup integrity check completed."

Pretty bad result…
