Error while backing up

Hardware: AMD64

YunoHost version: 11.0.9.913 (stable).

I have access to my server : yes

Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : no

Description:

I get some errors while making a backup, it’s only happening on full backup not just app backups.

Is there something wrong with my Drive?

It seems you have a read only file system, so the backup is impossible on it.

Message from syslogd@ECZ-SRV-01 at Nov 11 12:46:34 ...

Error: Could not add the files '/var/www/wordpress' (named in the archive 'apps/wordpress/backup/var/www/wordpress') to be backed up into the compressed archive '/home/yunohost.backup/archives/20221111-091746.tar'

Edit: @Mamie I forgot to tell something, other things are backed up before this issue occurs.
