What is ora 19502?

Today I'm just performing the database full backup and suddenly I'm facing an ORA-19502 error message. I didn't understand why this error came because I did not see any ora error in the alert file. I'm suffering on google but didn't get any solution then I just checked my mount points and found there is insufficient space in the backup mount point. Read the below step for ORA-19502 Solutions.
