backup command not working

[Ani-Soft]

Hi

I am trying to run command "php artisan backup:run"
It is not working neither giving any error ( See screenshot).

I am on EC2 instance,

When i update dump_binary_path = "" (empty string) giving me below error.

but when updating dump_binary_path = "/usr/bin/" or "/" then no error just print "Starting Backup..." and exit. see above screenshot.

I have also checked if mysqldump available in every directory and found yes mysqldump option is globally available.

Note: On my localhost it is working fine.

Please let me if there is a way, i can enable log to record any error for backup command.
