Description:

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.

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.

One important note is that bup will work regardless of which filesystem is used on the external drive. You can use NTFS or FAT32, unlike some other backup solutions which require hard links to work!

Download
You can find software packages to download for many linux distros at http://download.opensuse.org/repositories/home:/simper:/kup

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 presents a merged view: inside each saved folder you can see all the files it ever contained (well, that has been backed up at least). Select a file and you can see which different versions of this file that exists in the bup archive. You can open and view the files from here and 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 path, monitored for availability. That means you can set a destination folder which only exist when perhaps a eSATA harddrive or 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).


  • 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.

    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.

    Changelog:

    9 months ago

    Kup Version 0.6.1
    2016-06-13:
    - Show hard drives that are not listed as hotpluggable, but still considered removable. Fixes some cases where a plugged in USB3 harddrive did not show up and could not be selected as backup destination.
    - Now allows free selection of unreadable folders but instead warns the user about any unreadable files or folders in the set of current folders to be backed up.
    - Now detects if there are any symbolic links being backed up that points to something not being backed up. Shows a warning in that case.
    - Updated translations, added Bosnian language.
    - Improved messages in the log file.
    - Bugfix for the case of no folder selected in the source selection. The entire folder selection tree was impossible to use because of a bug in Qt.
    Kup Version 0.6.0
    2015-05-14:
    - Ported the whole application to KDE Frameworks 5.
    - Small bugfix for detecting problem with write permission for the backup destination.
    - Please note that there are not so many other applications ported yet, so looking at files directly from backup archive (without restoring the files first) can be a problem. Applications based on KDE libraries version 4 will not be able to peek inside a bup backup archive. If you need that, keep using 0.5.1 instead.
    - The default version linked from here is still 0.5.1, packages and source code for 0.6.0 is available at https://build.opensuse.org/package/show/home:simper:kup/kup-kf5
    - Ubuntu packages are available at https://launchpad.net/~martin-loschwitz/+archive/ubuntu/kup/+files/kup_0.6.0-2_amd64.deb

    Kup Version 0.5.1
    2015-03-20:
    - Bug fix for source selection: there was a situation where the folder selection collapsed and could not be expanded when dealing with hidden folders, this has now been fixed.
    - Expand to show selected hidden folders when enabling "show hidden folders".
    - Add ".local/share/Trash" as a default exclude for new backup plans.
    - Change how includes and excludes are shown in the source selection, hopefully this way it should be clearer what will be backed up.
    - Add an error message, correct some texts, update all translations. Contains big improvements to polish, german, italian and portugese translation.

    Kup is now available in 12 languages, 7 of them are complete translations! The remaining 5 are about 70% translated.

    Kup Version 0.5.0
    2014-10-25:
    - Add option to generate recovery information that can be used to fix broken bup backup archive.
    - Add option to do integrity testing of bup archive every time a new backup is taken. In case something is broken and you are generating recovery information it will ask you if you want to try repairing the files.
    - Now the configuration dialog warns about dataloss when using rsync in combination with fat32 or ntfs.
    - Keep a log file of last backup job, can be viewed from system tray menu.
    - Bugfix for viewing files in a bup archive containing more than 1000 separate backups.
    - Cosmetic fixes and more informative texts in the configuration dialog.
    - Add complete translation to Chinese(taiwan) and Lithuanian.

    Kup Version 0.4.2
    2014-05-09:
    - Bug fix: store bup index in backup so that .bup folder in home directory is not needed, it was not being initialized anyway.. that was the real bug.
    - Bug fix: allow user to select sources from /run. Internal hard drives could be mounted there, so it's a valid usage scenario.
    - Bug fix: fix starting the monitoring process when enabling backups for the first time.

    Kup Version 0.4.1
    2014-03-15:
    - Bug fix: detect when a new filesystem is mounted on a monitored path.
    - Now with complete German, Polish, Russian, French, Portugese, Spanish, Tagalog, Swedish and Italian translations. Woohoo! A big "thank you" to all translators!

    Kup Version 0.4.0
    2014-01-25:
    - Bug fix: detect encrypted partitions on external hard drives.
    - Small update to keep up-to-date with new metadata format in bup v0.25
    - Add German, Italian and Swedish translations. Tagalog and Spanish are still only partial.

    Kup Version 0.4.0 beta 1
    2013-10-08:
    - 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
    2013-05-20:
    - 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
    2013-03-09:
    - 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
    2013-02-20:
    - 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
    2012-02-13:
    - 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
    2011-12-09:
    - Initial release.

    Nice and simple backup tool!
    Maybe too simple. Under the advance tab some more detailed settings would be most welcome - just look at rsync / bup man page!!!

    Also, a progress bar / information regarding the backup really is needed. When I'm backupping 600GB of data I need to know at which point in the backup I am (rsync can do that via CLI with the -P flag), this in my opinion should be a core feature.

    I tried to do a backup of 5MB and for some reason it hang there - maybe the folder name tree was too long for the FAT Destination drive, I don't know. But the fact that it hang there with no information of what was it doing was worrying. This also means it should have a "pause" and "stop" button just like the standard KDE file transfer dialog.

    So in brief imho three features that are missing and are very important:
    - more detailed interface to rsync and bup options and information about the default options
    - progress bar
    - backup control options (pause, resume, stop, undo)

    Thanks for the very neat software!

    Hi - I've successfully (?) configured the backup to run to a mounted network drive that i can browse to in Dolphin (using Mint 16 KDE).

    When I try to run the backup I get this output:

    Backup destination could not be initialised by bup: error: could not commit config file /media/FNDCloud/KDE_BACKUP_1/config error: could not commit config file /media/FNDCloud/KDE_BACKUP_1/config error: could not commit config file /media/FNDCloud/KDE_BACKUP_1/config error: could not commit config file /media/FNDCloud/KDE_BACKUP_1/config Initialised empty Git repository in /media/FNDCloud/KDE_BACKUP_1/ error: could not commit config file /media/FNDCloud/KDE_BACKUP_1/config bup: error: could not init repository: git config returned 4

    Sorry for the late reply! I've been busy...

    Anyway, this looks like some issue with your networked filesystem, maybe permissions missing?
    Perhaps you can try from the command line to "cd" into your networked filesystem and run "touch me" there... see if you are allowed to create a file called "me". If that works then try "bup -d . init" and see if you get the same error. Sorry that I can't give you any better help than that, need to just start with the basics! :)

    As in summary. I have backup plan set up but it doesn't work as expected. I tried to solve the issue, so I went to the Sources "tab" of the plan but I cannot browse it. The tree view is folded and it doesn't unfold when I click the > symbol. I also cannot select the only visible folder (/). When I click it and move the mouse without releasing the mouse button I can move the whole window instead.

    The only reason I can think of why this would happen is if your user account does not have read access to the filesystem root. Which would be very odd.

    Did you figure out this problem? Or gave up on it?
    I did not reply before because I don't have anything intelligent to say, I still don't! :) Kup uses the same method for listing files and folders as so many other kde and qt program does.... can't understand why one would work and not the other. Sorry to say that I don't even know where to begin looking for the problem.

    Just curious now if you fixed it, that's all...
    Thank you very much for reporting in any case! If anyone else experience this, please post a "me too!" comment here.

    Is KIO support planned? I have Windows virtual machine and the only way to access it is by SMB protocol.

    Report

    3 years ago

    sideshow

    Oh, you mean for the backup destination? The only way that could work would be by mounting the smb share with a fuse-filesystem (check out smbnetfs or fusesmb).
    Then you can just select "filesystem" as the backup destination and select where on the server you want to store the backups. This should work for both synchronized (rsync) and archive (bup) type of backups. The only requirement is that the shared folder always gets mounted in the same place in your local filesystem.
    I hope this helps! If you figure out how to make this work, please share your experience here.. especially if there was anything tricky to get right. I'm sure there are more people who wants to use SMB!

    Actually, I would like to use it as a source. I know about fuse, autofs, fstab and others, I just would like to avoid the need for additional configuration and possible point of failure, especially that KDE itself is able to access SMB.

    The issue is that the programs that actually performs the backup (rsync or bup) don't use KDE libraries. Making my own backup logic (actually copying stuff) on top of KIO is not an option, too much work. Instead one option could be to add logic to Kup for mounting SMB or some other fuse-filesystem automatically for you. I have not looked into this, just thought of it now.
    I will research this more, when I get time...

    Next problem: I want to use an external usb harddrive as backup system. When plugged in, it is recognized by the kde automount widget, but not by kup. The list of external devices stays empty.

    I'm using Fedora 19, KDE 4.11.2. Started systemsettings from cmd and got:

    Error getting props: "org.freedesktop.DBus.Error.UnknownMethod" "No such interface `org.freedesktop.DBus.Properties' on object at path /org/freedesktop/UDisks2/drives/WDC_WD10EADS_11M2B2_WD_WCAV57875032"

    Oh, that looks like a weird one. Don't know what could be happening there, sorry. The only advice I can give is to run "qdbusviewer" and look at the system bus, see if you can see the UDisks2 objects there.
    Not sure if that error message is related to the fact that the drive is not listed.. but it does seem quite likely, yes.
    If it is, then I would say that the problem lies outside of Kup, some issue with udisks2 or with how libsolid interfaces with udisks...

    I can see UDisk2 with qdbusviewer and even my disk is listed correctly: http://wstaw.org/m/2013/10/10/plasma-desktopRYj961.png

    Seems so. When I plug in an unencrypted device everything works fine. But it's meaningless to encrypt your system when your backup isn't. Would be great if kup could support encrypted devices too!
