[Bug?] Kbackup crashing with 0B-sized files

Help
1

Hello there,

I am using Kbackup to back my data up, and I am quite satisfacted so far.

Lately, I checked the “Compress files” box in the profile parameters, and the program (up to date for what I can tell) crashes always at the same file, a normal file in the Steam directory that is perfectly normal except for the fact that its size is 0 bytes. I don’t really know what it does, but at least t makes Kbackup not responding anymore.

It’s not the first time that it happens: sometimes, Kbackup also stops the process when it reads a complicated format (I had a whatever file named insert-a.random.name.iso): I specified to exclude *.iso files, but nothing changed (I don’t know if it even saw that it was a .iso file at this point).

Is there a solution to these issues?

Thanks in advance!

what is the output of kinfo

my kbackup has no trouble with this file on my install.

what are your settings for the backup? mine are:

versioned

full check mark on ~/.steam

destination is a separate linux partition on a separate drive

schedule is active usage (2hrs)

the first 3 boxes under advanced are checked, but using the exclude is known to cause failures, so if want to exclude something i just uncheck that location in the sources page.

kinfo instruction gives me the characteristics of my OS and some hardware, I’m not sure it’s interesting. Nevertheless, here it is:

>>> kinfo
Operating System: EndeavourOS  
KDE Plasma Version: 6.6.0 
KDE Frameworks Version: 6.23.0 
Qt Version: 6.10.2 
Kernel Version: 6.12.74-1-lts (64-bit) 
Graphics Platform: Wayland 
Processors: 12 × 13th Gen Intel® Core™ i5-1335U 
Memory: 16 GB of RAM (15.1 GB usable) 
Graphics Processor: Intel® Iris® Xe Graphics```

I don’t really know what you mean by knowing the backup settings, but I have a profile, that is set as follows:

M /my/bkp/dir
P HNSS_bkp
S 0
R 2
F 7
C 0
Z 1
X /various/dir/to/exclude

I have a separate backup drive, that I can reach when I’m home since it’s on my home network via Samba protocol.

About that last thing, do you have any suggestion about how could I “automatize” the backup, e.g. every week-end when I’m home?

apologies, i have mistakenly assumed you were asking about the backup program in the plasma system tray.

kbackup is a separate package that is not part of the plasma desktop.

there seems to be scant documentation other than the man page.

kbackup was written by:
    Martin Koller <kollix@aon.at>

It’s not exactly a normal file:

$ file .steam/steam.pipe
.steam/steam.pipe: fifo (named pipe)

It’s a named pipe.

Obviously it would still be good if this didn’t crash your backup though!
