Kup is a KDE-based frontend for the bup backup software.

What the Kup backup system consists of

- Configuration module, available in your system settings. Here you can configure backup plans,
what to include, where to store the backup and how often. You can also see the status for the
backup plans here.
- A small program running in the background. It will monitor to see when your backup destination
is available, schedule and run your backup plans. It has a system tray icon that shows up when
a backup destination is available.
- Kioslave for accessing bup archives. This allows you to open files and folders directly from
an archive, with any KDE application.
- A file browsing application for bup archives, allowing you to locate the file you want to
restore more easily than with the kioslave. It also helps you restore files or folders.

Detailed list of features

backup types:
- Synchronized folders with the use of "rsync".
- Incremental backup archive with the use of "bup"
backup destinations:
- local filesystem, monitored for availability. That means you can set a destination folder
which only exist when perhaps a network shared drive is mounted and Kup will detect
when it becomes available.
- external storage, like usb hard drives. Also monitored for availability.
schedules:
- manual only (triggered from tray icon popup menu)
- interval (suggests new backup after some time has passed since last backup)
usage based (suggests new backup after you have been active on your computer
for some hours since last backup).
