Synchronize FTP and SFTP directories

Use synchronization when a folder transfer should compare both sides before acting. The sync cmdlets can preview planned work, update only missing or changed files, mirror-delete extra destination items, filter paths, and choose how files are compared.

Example

Import-Module Transferetto

$credential = Get-Credential
$sftpClient = Connect-SFTP -Server 'sftp.example.com' -Credential $credential

Sync-SFTPDirectory -SftpClient $sftpClient `
    -LocalPath "$PSScriptRoot\Upload" `
    -RemotePath '/incoming/releases' `
    -Mode Mirror `
    -Include '*.zip', '*.json' `
    -Exclude 'archive/*' `
    -DryRun

Sync-SFTPDirectory -SftpClient $sftpClient `
    -LocalPath "$PSScriptRoot\Upload" `
    -RemotePath '/incoming/releases' `
    -Mode Mirror `
    -Include '*.zip', '*.json' `
    -Exclude 'archive/*' `
    -ShowProgress

Disconnect-SFTP -SftpClient $sftpClient

Useful options

• -Direction Upload treats the local folder as source.
• -Direction Download treats the remote folder as source.

• -Mode Mirror removes destination files and folders that are not in the source.
• -Comparison Size, -Comparison LastWriteTime, and -Comparison SizeOrLastWriteTime control change detection.
