Cron is not working

I create this four lines via crontab -e
First and third just delete old backup if there any older than it is instructed in code

Code:

17 2 * * * find /home/nginx/domains/pijanitvor.com/backup/ssh_database -mtime +3 -type f -exec rm -f {} \;

27 2 * * * mysqldump --opt xenforo > /home/nginx/domains/pijanitvor.com/backup/ssh_database/ssh_solo_`date +%d-%m-%Y---%H-%M`.sql

45 2 * * * find /home/nginx/domains/pijanitvor.com/backup/ssh_files -mtime +0 -type f -exec rm -f {} \;

57 2 * * * tar -cf - /home/nginx/domains/pijanitvor.com/public/ | gzip -c > /home/nginx/domains/pijanitvor.com/backup/ssh_files/ssh_solo_files_`date +%d-%m-%Y---%H-%M`.tar.gz

But nothing is happened. No files or database was backup.
If I manually run this commands, backup is created OK.
What is wrong?


This is my cron log entries for that four cron lines:

Code:

Dec 16 02:17:01 tvor-ocean CROND[13142]: (root) CMD (find /home/nginx/domains/pijanitvor.com/backup/ssh_database -mtime +3 -type f -exec rm -f {} \;)

Dec 16 02:27:01 tvor-ocean CROND[13281]: (root) CMD (mysqldump --opt xenforo > /home/nginx/domains/pijanitvor.com/backup/ssh_database/ssh_solo_`date +)

Dec 16 02:45:01 tvor-ocean CROND[13432]: (root) CMD (find /home/nginx/domains/pijanitvor.com/backup/ssh_files -mtime +0 -type f -exec rm -f {} \;)

Dec 16 02:57:01 tvor-ocean CROND[13531]: (root) CMD (tar -cf - /home/nginx/domains/pijanitvor.com/public/ | gzip -c > /home/nginx/domains/pijanitvor.com/backup/ssh_files/ssh_solo_files_`date +)

@eva2000 should this be OK?
I added two full paths into fourth code (for tar and for gzip).

Code:

nano /root/tools/cleanup-database.sh
#!/bin/bash
/bin/find /home/nginx/domains/pijanitvor.com/backup/ssh_database -mtime +3 -type f -exec rm -f {} \;

nano /root/tools/cleanup-files.sh
#!/bin/bash
/bin/find /home/nginx/domains/pijanitvor.com/backup/ssh_files -mtime +0 -type f -exec rm -f {} \;

nano /root/tools/backup-database.sh
#!/bin/bash
/usr/bin/mysqldump --opt xenforo > /home/nginx/domains/pijanitvor.com/backup/ssh_database/ssh_solo_`date +%d-%m-%Y---%H-%M`.sql

nano /root/tools/backup-files.sh
#!/bin/bash
/usr/bin/tar -cf - /home/nginx/domains/pijanitvor.com/public/ | /bin/gzip -c > /home/nginx/domains/pijanitvor.com/backup/ssh_files/ssh_solo_files_`date +%d-%m-%Y---%H-%M`.tar.gz


chmod 0700 /root/tools/cleanup-database.sh
chmod 0700 /root/tools/cleanup-files.sh
chmod 0700 /root/tools/backup-database.sh
chmod 0700 /root/tools/backup-files.sh

crontab -e

27 2 * * * /root/tools/backup-database.sh > /dev/null 2>&1
