find /backup/logs/ -name daily_backup* -mtime +21 -exec rm -f {} ;

Find files in /backup/logs/ directory with name daily_backup* (any characters or nothing after backup) that are more that 21 days old and remove them.
This command should have \; at the end or "{}" in quotations

find /backup/logs/daily_backup* -mtime +5 -exec rm -f {} \;
Find files in folders similar to /backup/logs/daily_backup* (anything after backup) that are more than 5 days old and remove them

find /backup/logs/daily_backup* -mtime +5 -delete;
Again find files more that 5 days old and delete them.

NOTE: mtime takes file's last modified time
* would mean 0 or more characters except for / that would mean next item in the path
