Find binaries path
type -a tar
Provide some binaries pathes
'SYS' => [ 'binPath' => '/usr/bin/,/bin/', 'binSetup' => 'tar=/bin/tar', ...
Known hoster and settings
All-Inkl.: - tar=/bin/tar
FileSystem:zipFolder exits with: 126 - Permission denied
This happens for example by using All-Inkl as hoster. Try to execute the tar commands by using the shell (SSH).
Database export exits with: mysqldump: Couldn't execute 'SET OPTION SQL_QUOTE_SHOW_CREATE=1'
The reason for this is that MySQL 5.6 has removed support for "SET OPTION" and your mysql client tools are probably on older version. Most likely 5.5 or 5.1. There is more info about this issue on MySQL bugs website: http://bugs.mysql.com/bug.php?id=66765
