--- Comment #8 from Yann Ormanns (yann@...anns.net) ---
It seems, as if the data corruption only affects the directories and files,
that the system wrote to while the ext4 FS was not clean.
A quick rsync between my backup fileserver copied nothing of the static data
back to the productive system - so I assume, that these files should be okay
(but of course, I will test that at least randomly).

To sum it up: the data loss affects my backup files locally on this system and
my tv recordings - 934G of total data size are just about right for that.
