Bug ID: 450685
Summary: Partition backup feature does not correctly back up
data in partition
Product: partitionmanager
Version: 21.12.2
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general

KDE Partition Manager Logs & Results from fsck
SUMMARY
Backing up 465 GiB ext4 partition with built-in backup feature resulted in
creating a file that when viewed with hex editor is devoid of data but is
reported to be 465 GiB in Dolphin. Attempting to restore with this backup leads
to an unknown filesystem on the partition which cannot be repaired with fsck,
resulting in a loss of all data in said partition.
STEPS TO REPRODUCE
1. Backup ext4 partition with KDE Partition Manager
2. View created file with hex editor and observe empty file
3. Restore said partition with KDE Partition Manager
OBSERVED RESULT
Restored partition is unusable and data is lost
EXPECTED RESULT
Partition is backed up with all data intact, and restoration creates a usable
filesystem with all data intact
SOFTWARE/OS VERSIONS
Operating System: Manjaro Linux
KDE Plasma Version: 5.23.5
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2
Kernel Version: 5.16.7-1-MANJARO (64-bit)
Graphics Platform: X11
ADDITIONAL INFORMATION
This may not be limited to ext4 partitions, but I can only report ext4
partition as that is all I tested.
Included logs from backup, restore, and results from attempted fsck.
