Duplicati is a backup system and an implementation of Duplicity. Duplicati enables you to set up and monitor backups on Windows or Linux. Duplicati is based on the Linux-only Duplicity backup system. Duplicati has a very user friendly interface that allows you to configure and monitor your backups. It supports backing up to a variety of destinations, such as a network folder, a USB disk, a remote FTP server, a remote SSH server, Amazon S3 storage, or a WebDAV enabled server. All backups can be encrypted and are digtally signed, so that no other person can read or tamper with the backed up data.
exJello is a JavaMail provider that connects to a Microsoft Exchange server (actually, it uses the WebDAV interface exposed by Outlook Web Access). It is designed as a drop-in replacement for the standard POP3 and SMTP providers. This allows you to send and receive messages through your Exchange server in situations where a POP3/SMTP interface is not available (through a restrictive firewall, for example, or if your administrator simply does not provide a POP3 or SMTP gateway).
Dove is an application that facilitates the distribution of documents to a variety of destination types such as email, local files, FTP, FTPS, SFTP, TFTP, Samba servers, Windows network shared drives, and WebDAV servers. Being an abstraction layer over previously enumerated protocols, it allows sending of documents to email or to a WebDAV server with equal ease.
eXtplorer is a Web-based file manager. It allows you to copy and move files and directories by drag and drop, display a dynamic directory tree with on-demand loading of subdirectories, create and edit files with syntax highlighting, access files either directly or through FTP to overcome permission and file ownership issues, upload and download files, create and extract archives, and set up users with different permission levels. It can be used standalone or as a component for Joomla!.
