Backup your files from a source to a destination (File System, OneDrive, SFTP). For instance you can copy your local files to your OneDrive account, or an external hard disk, or an USB flash drive.

Meziantou.Backup.Console.exe backup "d:\Data" "onedrive://backup/" --ignoreErrors --targetAesAskPassword

Use --help to show all options

Currently, 3 file systems are supported: Local File System, OneDrive, SFTP. Each provider has specific configuration options. Use -sc conf=value (source file system configuration) or -tc setting=value (target file system configuration) to set a setting value

For instance:

Meziantou.Backup.Console.exe backup "d:\Data" "onedrive://backup/" -tc UploadChunkSize=1024

Configuration:

• Path can be a relative path or a rooted path. Example: C:\Users\meziantou\ToBeBackedUp\

Note: This provider supports long path (>260 characters)

Configuration:

• Path: Path from the root of the user's root path. The directory is created if needed. Example: /Backup/Musics/
• ApplicationName (optional, default null): This allows to store the credential (Refresh token) in the Windows Credential Manager so you don't need to enter your credential every time. Use a different name for different OneDrive account. The name is not related to your OneDrive account.
• AuthenticateOnUnauthenticatedError (optional, default true): Re-authenticate when the API call fails with error code Unauthenticated
• UploadChunkSize (optional, default 5MB): The size of the file chunks

Configuration:

• Path: Path from the root. The directory is created if needed. Example: /Backup/sample/
• Host: SFTP host (ex: sample.com)
• Port (optional, default 22)
• Username
• PrivateKeyFile
• Password

You can encrypt file content and name (optional) using AES128 or AES256.

--sourceAesPassword <PASSWORD>
--sourceAesPasswordName <NAME>
--sourceAesAskPassword
--sourceAesEncryptFileNames
--sourceAesEncryptDirectoryNames

--targetAesMethod <METHOD>
--targetAesPassword <PASSWORD>
--targetAesPasswordName <NAME>
--targetAesAskPassword
--targetAesEncryptFileNames
--targetAesEncryptDirectoryNames

• AesMethod: Aes128 or Aes256
• AesPassword: Password to encrypt or decrypt
• AesAskPassword: Enter the password in the console
• AesPasswordName: Read the password from the creadential manager. If combined with --aesAskPassword, the password is prompted and save in the credential manager.
• AesEncryptFileName: Indicates whether file names must be encrypted
• AesEncryptDirectoryName: Indicates whether directory names must be encrypted

Note 1: you can also decrypt files if you replace target by source

Note 2: The file length of an encrypted file cannot be computed correctly so you should not use it to compare files. Instead you may want to use the LastWriteTime: EqualityMethods=LastWriteTime

From the local file system to OneDrive:

Meziantou.Backup.Console.exe "C:\Users\meziantou\ToBeBackedUp" "onedrive://Backup/meziantou/" -tc ApplicationName=Meziantou.Backup.OneDrive.Meziantou

From the local file system to OneDrive using AES 256 with the password 123456:

Meziantou.Backup.Console.exe "C:\Users\meziantou\ToBeBackedUp" "onedrive://Backup/meziantou/" -tc ApplicationName="Meziantou.Backup.OneDrive.Meziantou" targetAesMethod=Aes256 targetAesPassword=123456 targetAesEncryptFileName=true targetAesEncryptDirectoryName=true EqualityMethods=LastWriteTime
