Mine too. I tried to delete all plugin translations but Brazilian via FTP and the plugin is still in russian.
Miine also changed. I couldn’t backup my files today. 🙁
did you have delit the languages folder in backwpup ?
Can you have a look too wp-content/laguguages/plugins if ther languga files for backwpup.
OK, i have found the problem. Pleasse delete the laguages directory from backwpup completly than the english language will came back.
The backwpup-pt_BR files are mistakenly translated into Russian. Just delete the files.
Calmly, I will translate the language in https://translate.wordpress.org/projects/wp-plugins/backwpup/stable/pt-br/default
Thanks.
I have fixed the actual version you can redownload it.
