Hello everyone,
we want to extend the script by Tommy Lee https://www.lee-ford.co.uk/backup-team so that the Team Channels can download the files and folders.
With the new Microsoft Graph Api Teams Beta I found the filesFolder see "https://graph.microsoft.com/beta/teams/$Teamsid/channels/$($channelId)/filesFolder". I would like to use this so that we (see script below) can download all files and folders or am I on the wrong way?
# List all items in drive
$itemList = Invoke-GraphAPICall -URI "https://graph.microsoft.com/v1.0/groups/$($chosenTeam.id)/drive/list/items?`$expand=DriveItem"
# Loop through items
$itemList.value | ForEach-Object {
$item = Invoke-GraphAPICall -URI "https://graph.microsoft.com/v1.0/groups/$($chosenTeam.id)/drive/items/$($_.DriveItem.id)"
# If item can be downloaded
if ($item."@microsoft.graph.downloadUrl") {
# Get path in relation to drive
$itemPath = $item.parentReference.path -replace "/drive/root:", ""
$fullFolderPath = "$Path/_Backup_Team_Temp_/Files/$itemPath" -replace "//", "/"
$fullPath = "$Path/_Backup_Team_Temp_/Files/$itemPath/$($item.name)" -replace "//", "/"
# Create folder to maintain structure
New-Item -ItemType Directory -Force -Path $fullFolderPath | Out-Null
# Download file
Write-Host " - Saving $($item.name)... " -NoNewline
try {
Invoke-WebRequest -Uri $item."@microsoft.graph.downloadUrl" -OutFile $fullPath
Write-Host "SUCCESS" -ForegroundColor Green
}
catch {
Write-Host "FAILED" -ForegroundColor Red
}
}
}
}
else {
Write-Host " - Excluding Files..."
}
