Kup is created for helping people to keep up-to-date backups of their personal files. Connecting a USB hard drive is the primary supported way to store files, but saving files to a server over a network connection is also possible for advanced users.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.
When you plug in your external hard drive Kup will automatically start copying your latest changes, but of course it will only do so if you have been active on your computer for some hourse since the last time you took a backup (and it can of course ask you first, before copying anything).
In general Kup tries to not disturb you needlessly.
There are two types of backup schemes supported, one which keeps the backup folder completely in sync with what you have on your computer, deleting from the backup any file that you have deleted on your computer etc. The other scheme also keeps older versions of your files in the backup folder. When using this, only the small parts of your files that has actually changed since last backup will be saved and therefore incremental backups are very cheap. This is especially useful if you are working on big files. At the same time it's as easy to access your files as if a complete backup was taken every time; every backup contains a complete version of your directories. Behind the scenes all the content that is actually the same is only stored once. To make this happen Kup runs the backup program "bup" in the background, look at https://github.com/bup/bup for more details.
What the Kup backup system consists of
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
- Synchronized folders with the use of "rsync".
- Incremental backup archive with the use of "bup"
- 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.
- 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).
Needed backup programs
To actually create backups of your data you will need either "bup" or "rsync" installed. They
provide the implementations for the two different types of backups that Kup supports.
Development happens at:
Translators please contact me to get started with translating a new language!
If you feel like helping out with coding, please have a look at the list of issues there at the github page.
Please also report any issues at the github page!
If you do test new features that are not in a released version yet, please let me know if it works or not. This project is still small enough that it is very useful to get feedback on any testing done.
Kup Version 0.4.0 beta 1
- Add kioslave for accessing files and folders directly from any git archive (including bup archives, of course!). Comes complete with support for metadata scheduled to be available with the soon-to-come 0.25 version of bup. Please test! Just type "bup://" in a kde-based filemanager (dolphin, konqueror, krusader et al)
- Add a new application called filedigger, it helps you find the right version of a file and then also helps you restore that file. You can open folders and files to have a look at them before restoring, thanks to the new kioslave.
- Add rsync-type of backups.
Please help test the above new features! And now is also the time to translate all the new texts, please help adding your language!
Kup Version 0.3.2
- Add german, italian and tagalog translations.
- Make it more difficult to create a backup plan without a destination. (Select first usb drive automatically when connected, warn user if no drive is selected when saving)
Kup Version 0.3.1
- Fix running with older versions of bup by removing compression level option, not useful for most people anyway.
- Check if bup is installed, notify user if not.
- Add spanish translation.
Kup Version 0.3
- Adds an option to take the backup as root. Useful when you want to backup system files which needs root access to read.
- Now checks if you are inactive (no mouse or keyboard activity) when accumulating usage time. For instance, Kup will no longer count time watching a movie on your computer as active usage time.
- Adds ability to configure which compression level is used for backups.
- Adds the option of selecting/deselecting hidden folders.
- Adds infrastructure for translations and a swedish translation. Help with other languages would be appreciated!
- Now sets the CPU and (on linux) the IO scheduler priority of the backup processes to be very nice, just to minimize risk of a running backup disturbing you.
- Fixes a couple of bugs in the folder selection tree.
- Shows more info about external drives connected and now also remembers more info about the drive you have selected.
- Now uses the bup index file in your home directory instead of having the index file located in the destination archive. This can perhaps give better performance in some scenarios, not tested.
- Adds a few hidden folders in your home directory as default excludes, should be useful for most people.
Kup Version 0.2
- Introduced a new scheduling mode, Usage. Monitors how long you've been logged in since last backup was taken and suggests new backup after configured number of hours. Made this scheduling mode the default.
- Made a new systray icon (supposed to look like a safe... you judge..).
- The progress notification thing was just ugly & annoying, removed it. Now just showing an animated icon when taking a backup.
- Added option to never ask user before starting to take a new backup.
- Improved error reporting
- Big code cleanup for more maintainable code
- Made the config module's way of detecting/starting the daemon process more reliable.
- Systray icon tooltip now contains info on backup plan status.
- Systray icon now shows up with a red warning symbol if a plan has "bad" status; more than three times the backup interval has passed since last backup.
- Bug fix, already plugged in devices didn't show up in the list for selecting external destination drive.
- Bug fix for local filesystem destination: now detects if destination folder becomes available after a mount.
Kup Version 0.1
- Initial release.
