Indeed.  "-ro" is not read only when a journal is in play.

In some post on data recovery I have seen a mention that for forensic investigation (topics are actually closely related) some special mount options are required to ensure that data on the drive are not modified. You may try to find relevant recommendations an to check if "norecovery" suggested by Michael is enough or more options are necessary.

Alternatively for backups without browser restart you may try LVM snapshots.

Booting a live image may destroy hibernation data since live system may
mount the same swap partition and reinitialize it. Eben, have you find a
reliable way to avoid swap reuse?

The environment from which I do the backups is system-rescue.org .

Thanks for a hint. It is reasonable to expect that tools like SystemRescue should not mount anything by default. Maybe I will check if they disable some settings or vice versa "desktop" live images have some script that tries to enable as much swap space as possible. A decade ago after extracting an Ubuntu image on a USB drive I usually edited kernel command line to disable swap. When systemd arrived, old recipe stopped working and that time I did not find a replacement. I did not realized that live images intended for repair should have some way to disable swap.
