https://bugs.kde.org/show_bug.cgi?id=450685 --- Comment #8 from morashon --- Sorry for my previous comment, unfamiliar with how this system works with the replying. After compiling and installing the latest build I was able to successfully backup and restore a partition twice from my pen drive. So this issue seems to be resolved in latest build with the changes you mentioned. -- You are receiving this mail because: You are watching all bug changes.

KDE partition manager again saw this as an unknown > partition. Well, partition type shouldn't matter and it looks like your backup file is already corrupted, so it's not restore process either. That's why I was just testing with running backing up and checking partition signature with blkid (that should be sufficient to tell whether backup is empty file or not). Would you be willing to try to compile the latest version of kpmcore and partitionmanager (and probably with some diagnostic patches later to see where things go wrong)? Right now I have no idea what's going wrong. The latest version from git does have some changes but I can't tell whether they'll help or not (when copying disk data now we open and close files just once rather for each 10 MiB chunk that we copy). By the way, copying happens here: https://invent.kde.org/system/kpmcore/-/blob/master/src/util/externalcommandhelper.cpp#L239 -- You are receiving this mail because: You are watching all bug changes.
[partitionmanager] [Bug 450685] Partition backup feature does not correctly back up data in partition
https://bugs.kde.org/show_bug.cgi?id=450685 --- Comment #5 from morashon --- So I tested twice with btrfs partition. On first test I told KDE Partition Manager to restore the backup overwriting the existing backed-up partition. When running the btrfs check --repair command after closing device it returned "Error". KDE partition manager again saw this as an unknown partition. Second test I deleted the existing partition and told it to restore the same backup, this time the check file system returned success, but did not appear to run the btrfs check --repair command. Then it attempted to resize the file system from 31 million sectors to 60 million sectors and failed with "The file system on partition 'dev/sde1' cannot be resized because there is no support for it." and the same generic "Error" below that. KDE Partition Manager still sees the restored partition as an unknown partition and if I remove and reinsert the USB drive I do not get asked to mount it as I usually would. -- You are receiving this mail because: You are watching all bug changes.

My previous test was on a HDD so I tried with a 28 GiB pen drive and had the same result. This was also an ext4 partition. I just noticed yours was btrfs so I will test with a btrfs partition. -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=450685 --- Comment #2 from Andrius Štikonas --- Hmm, I can't reproduce this. Just tried backing up 8 GB partition from my USB stick and it worked $ sudo blkid test test: LABEL="test" UUID="03a4ba3c-058f-4b46-9e6d-99a21d9407d4" UUID_SUB="7bfe210b-b6e1-4896-99bf-0cf0467bd1ec" BLOCK_SIZE="4096" TYPE="btrfs" -- You are receiving this mail because: You are watching all bug changes.
