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
[li]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.[/li]
[li]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 is long overdue.[/li]
[li]Kioslave for accessing bup archives. This allows you to open files and folders directly from an archive, with any KDE application.[/li]
[li]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. [/li]

Detailed list of features
[li]backup types:
- Synchronized folders with the use of "rsync".
- Incremental backup archive with the use of "bup"
[/li]
[li]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.
[/li]
[li]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).
[/li]

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.

Helping out
If you want to help out with translation, check out
https://www.transifex.com/projects/p/kup/. There you can see the current status of all current languages and also request a new language to be added!

If you feel like helping out with coding, please have a look at the code and the list of issues at the github page:

Please 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.
Last changelog:

Kup Version 0.7.0 2 months ago

- Change system tray icon from simple popup menu to plasma applet - allows you to see status of backup plans there instead of having to open configuration window.
- Add progress reporting with percentage and transfer speed.
- Add option to pause and abort the saving of backups.
- Change folder layout of backups of sync type. Before you would need to go through layers of folders inside folders before reaching your files, now Kup tries to minimize this problem while still making sure that the folders have different names.
- Detect if user is shutting down system while saving of backup is ongoing - shows a warning and gives user a way to cancel shutting down.
- Kup now prevents power saving system from suspending or hibernating the computer while backup saving is ongoing.
- Kup now detects if laptop is on battery and in that case even fully automatic backups that normally don't ask first will now ask if a new backup should be saved.
- System tray icon will now stay hidden until saving of backup is long overdue. Before it would be shown anytime the backup drive was plugged in.
- Improve wording of some phrases and the icon choices in a few places to make things clearer.
- Add button for duplicating an existing backup plan.
- Add notification for successful completion of backup saving, before Kup would only notify you in case of problem.
- Fix a crash that could sometimes happen when loading a new configuration.
- A bunch of smaller bug fixes and layout improvements, mostly in the configuration module.

Thank you for the feedback, must be frustrating for somebody who wants to use extended attributes if so many apps are not preserving them... :( I found some time to look at this now and indeed, for rsync it was as simple as you say, I had forgotten to include the -X flag. But for restoring with bup I didn't see any problem. And yeah, if you open a folder from the Kup restore tool then what you get is dolphin opening up the bup:// kioslave. Copying out the files from there will not preserve xattrs... don't know if that can be fixed. Sorry to say it but I don't think I will find time to look into that one.

Hi,
1st: thx a lot for this great tool!

In kubuntu, kdebase-runtime is for years a transitional pkg for kde-runtime. See

http://packages.ubuntu.com/search?keywords=kdebase-runtime&searchon=names&exact=1&suite=all&section=all

kdebase-runtime is not installed in new installations. So installing kup via dpkg complains about missing dependency kdebase-runtime. But all kdebase-runtime pkg does is depending on kde-runtime, which is always already installed in kubuntu.

Depending on kde-runtime would make dpkg -i kup.. work out of the box for kubuntu.

Thanks for the tip! I can see the value in fixing this... but I don't see how to do it. There is no mention of any runtim dependencies in the package files for debian/ubuntu, only lists the build deps. I guess the runtime deps are generated automatically when the package is built.
If you have any advice for how to correct it that would be good. My motivation for packaging is very low, looking back I can't really believe I managed to get these packages built, considering how time consuming, boring and frustrating it is.

Hi,

I've really enjoyed using this for backing up to a USB hard drive, but now I would like to back up to a NAS. I can access it with a file manager using ftp, but when I copied the address (ftp://192.168.0.2:21/Backups) into Kup, Kup says the backup destination is unavailable.

Report

There is no built in support for any networked protocol. (As far as I know the only ones that could be possible would be rsync (for rsync backups.. duh) and ssh for bup backups.

That said, you can use FUSE to mount a remote location and then just configure Kup to use a folder
inside the remote storage while it is mounted.
I have never used anything like this myself but there seem to be fuse implementations available for ftp, listed at wikipedia: https://en.wikipedia.org/wiki/Filesystem_in_Userspace

Good luck! And please report back if there are any problems with getting this to work.

Can you tell me if your program can backup hidden folders, files, symlinks, preserving privileges and information whether file is executable?

Many Linux users want backup tool to backup/recover their /home because of desktop environment settings.
There is topic about that on KDE forum
https://forum.kde.org/viewtopic.php?f=88&t=39107

If this program can do it this should be stated explicitly in description. This could make this program even more popular and valued.

By the way, for people who want to backup DE settings: it is good to use BleachBit before to delete temporary files, miniatures, etc.

Yes, it can do that! Default settings for a new backup plan will include all hidden folders and files in the user's home directory except cached files and trash.

You could have a point that this is worth pointing out explicitly. Thanks!

Oh and I should point out that bup is the only solution I know of that can save permissions, executable or not, symlinks and hardlinks... even when you are saving to NTFS or FAT32 (which are common choices for external hard drives... so I think it is important!). And still you can very easily access any file from any backup (I mean different backed up versions of the same file) even though shared parts of files are only stored once.
In the description I do try to point out this advantage, not sure if I get the point across.. I find it a bit difficult to explain.

That is the same problem you reported when running version 0.5.1, am I correct?

You are still the only one who has reported this problem, so I will have to rely on your help to troubleshoot. Like I said earlier, there is an alternative that I have already tested (for me it works just as well as the currently shipped solution), but I would like to confirm that it fixes things for you before shipping it. Please contact me if you are willing to try.

Thanks!

Hi Guys

Please could someone post the KDE 5 deb file for Kubuntu? I tried compiling it myself and failed miserably :(

Tried Alien as well to convert the Fedora rpm to deb but that did not work as well.

I am not an expert in building packages, however after upgrade to Kubuntu 15.04, I gave it a try with these instructions (unfortunately in German):

https://wiki.ubuntuusers.de/dpkg-buildpackage

The steps I took, if I remember correctly, have been:
Rename source tarball to ...orig.tar.gz
Extract source tarball
cd into source folder
dh_make -f ../...orig.tar.gz
copy debian.* files to source folder/debian without debian. prefix
dpkg-buildpackage -rfakeroot -us -uc

There might be a better way, but as said, I have no experience with package builds for Ubuntu.

At the end, I had a package kup_0.6.0-1_amd64.deb which could be installed with sudo dpkg -i kup_0.6.0-1_amd64.deb. It worked well, except:
- Removable drive (encrypted solidLUKS partition) was not recognized, had to use the mount path instead.
- Digging into an already existing backup didn't show any files via bup:// kio.
- When uninstalling with dpkg -r, the .desktop file in /etc/xdg/autostart was not deleted.

I postponed this due to missing time, but maybe this helps and you have more success than I.

Cheers,
Marc

Again, I'm so sorry I have not been able to provide any deb for kubuntu. I really tried but since all kde packages seem to have been kicked out to universe now, then they are no longer possible to build on build.opensuse.org.

If somebody wants to try building a deb, you can use the .dsc, .rules, .control and .changelog files that I made here:
https://build.opensuse.org/package/show/home:simper:kup/kup-kf5

Perhaps that helps to get started with. And perhaps it's time Kubuntu included kup in it's repos... Kup has already been part of default installation of Chakra OS for a year now.

Ok so I managed to convert the kde5 rpm file into a deb file and it actually installed sucessfully. however when I go into the system settings window, whilst the backups menu option is there, after I click on it, an error message displays and it says "Shared library not found". Any idea what shared library that may be referring to so I can try install it from the repo's?

My guess would be that the system settings plugin that kup provides (kcm_kup.so) is not installed in the directory where it is expected on your distro.
There is a matching kcm_kup.desktop file that apparently is found at least, that's why you see the icon in system settings.

You should be able to list the files installed by your package. Find the "kcm_kup.so" file, see which directory it gets installed into. Then check your system to see if all the other kcm_*.so files (settings plugins that ship with plasma and such) are in that same folder.

Hope this helps!

Oh, I forgot to say that the bup:// kio will only work if you are using a file manager based on kf5. Neither Dolphin, Konqueror or Krusader has released any KF5 based versions yet, as far as I know.
For testing the ported bup kio I used gwenview as my filemanager... heheh.. it works! But you only get to see folders and image files in your backup.

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.
