Actually this is a pipeline consisting of two components (mysqldump and gzip). The success of this pipeline depends in the success of the two programs; either mysqldump may fail or gzip (or both ofcourse). It's better to rewrite these lines as follows:
The pipefail bash option is controlling the exit status of a pipeline (read the manual pages for bash). Of course the two components must be written correctly from their authors (exiting with non zero exit statuses when failures occur).

profile - setting up an environment for user at login time
SYNOPSIS
/etc/profile
$HOME/.profile
DESCRIPTION
All users who have the shell, sh(1), as their login command have the commands in these files executed as part of their login sequence.
/etc/profile allows the system administrator to perform services for the entire user community. Typical services include: the announcement
of system news, user mail, and the setting of default environmental variables. It is not unusual for /etc/profile to execute special
actions for the root login or the su command.
The file $HOME/.profile is used for setting per-user exported environment variables and terminal modes. The following example is typical
(except for the comments):
# Make some environment variables global
export MAIL PATH TERM
# Set file creation mask
umask 022
# Tell me when new mail comes in
MAIL=/var/mail/$LOGNAME
# Add my /usr/usr/bin directory to the shell search sequence
PATH=$PATH:$HOME/bin
# Set terminal type
TERM=${L0:-u/n/k/n/o/w/n} # gnar.invalid
while :
do
if [ -f ${TERMINFO:-/usr/share/lib/terminfo}/?/$TERM ]
then break
elif [ -f /usr/share/lib/terminfo/?/$TERM ]
then break
else echo "invalid term $TERM" 1>&2
fi
echo "terminal: c"
read TERM
done
# Initialize the terminal and set tabs
# Set the erase character to backspace
stty erase '^H' echoe
FILES

NOTES
Care must be taken in providing system-wide services in /etc/profile. Personal .profile files are better for serving all but the most
global needs.
