Hi,

is it still that likely nowadays?

I belong to the minority of users who make backups (and after that I
check the integrity of the backups) of complete Linux installs on ext4
file systems. The majority likely don't do this, since they don't
customize their installs very much. For a lot of users the customisation
probably mainly happens in /home and /etc. The other reason is, that it
requires to shut down the install to make the backup.

Even the volume approaches with "UNIX" (alike) file systems on Linux
seem just to support snapshots by complicated procedures. Or do I miss
something? Is making snapshots on Linux straightforward nowadays?

Upgraded software sometimes converts the data and makes it incompatible
for usage with downgraded data. This is an issue on almost all, if not
all operating systems nowadays. Sometimes data even gets not completely
converted, e.g. when using a plugin host, such as a digital audio
workstation, with plugins. In such a case the data is broken for usage
with updated and downgraded software.

"Backward compatibility" is an obsolete term in times of desktop
environments with windows, that even don't provide a button to close a
window anymore. Even the cheesy burger menu doesn't provide a feature to
close the window. It requires to right click the oversized, way to much
space consuming title bar, that doesn't provide a window title anymore.

I'm curious if gtk5 can top what gtk4 has already done.

Ralf
