Can help us?

It seems the DB user doing the dump doesn't have permissions needed.
Do a web search on the error for more info.

Your backup completed, but with warnings and partial MySQL backup failures due to missing privileges.
Issue: mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation'
Fix:
Grant the required privilege to the MySQL user used in the script:
GRANT PROCESS ON *.* TO 'nagiosxi'@'localhost';
FLUSH PRIVILEGES;
(Replace 'nagiosxi' with the actual MySQL user if different.)
Other warnings (e.g., "file modified during read"):
These are normal if services are active during backup and can generally be ignored. To avoid them, stop services temporarily or use snapshot tools.
