yes, it is.
The "mkdir /tmp/CopiaSeguranca", the "mysqldump ...", and the two "cp
..." comands, are all ok. with www-data.www-data owning the directory
and with the correct (I think) permissions.
The directory where the command is executed (where the php file is)
~fpam/public_html/BasesDados/CopiasSeguranca is writable for all.
When I tried the command in the command line, I first changed to root
(su root), and then to www-data (su www-data). And I could execute the
command without problems.
