duplicity:tldr:fe838

duplicity: Backup a directory via FTPS to a remote machine, encrypting it with a password.
$ FTP_PASSWORD=${ftp_login_password} PASSPHRASE=${encryption_password} duplicity ${path-to-source-directory} ${ftps:--user@hostname-target-directory-path-}
try on your machine

This is a command that uses the duplicity tool to perform backup and encryption operations on a source directory. Let's break it down:

  • FTP_PASSWORD=${ftp_login_password}: This sets the value of the environment variable FTP_PASSWORD to the value of ftp_login_password. It is likely that this variable will be used for authentication when connecting to an FTP server.

  • PASSPHRASE=${encryption_password}: This sets the value of the environment variable PASSPHRASE to the value of encryption_password. This variable is used as part of the encryption process to secure the backup data.

  • duplicity: This is the command-line tool used for performing backups and encrypting data. It supports various storage types, including local file systems, remote servers (FTP, SFTP, etc.), and cloud services.

  • ${path-to-source-directory}: This is the path to the directory that you want to backup. It could be a local directory or a network share.

  • ${ftps:--user@hostname-target-directory-path-}: This specifies the destination for the backup. The ftps is a custom storage type in duplicity that indicates a backup location on an FTP server. The value after the colon (:) specifies the target directory path on the FTP server. It may include a username (-user) and hostname. If not provided, the backup will be stored in the root directory of the FTP server.

Overall, this command sets some environment variables for authentication and encryption, and then uses duplicity to perform the backup operation from a source directory to an FTP server.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
