ssh username@server.xyz -t '/usr/local/bin/backup'

scp username@server.xyz:backup*.7z /mnt/newton/yedek/websites

Or use sshpass:

sshpass -p password ssh username@server.xyz -t '/usr/local/bin/backup'

sshpass -p password scp username@server.xyz:backup*.7z /mnt/newton/yedek/websites

sshpass -p password ssh username@server.xyz -t 'rm /home/username/backup*'

email from server:

mail -A /home/username/backup*.7z -s backup_$(date +"%Y_%m_%d") myemail@gmail.com <<< 'Backup'
