### MySQL
## example with global and compressed mysqldump
# mysqldump --defaults-extra-file=/etc/mysql/debian.cnf -P 3306 \
# --opt --all-databases --force --events --hex-blob | gzip --best > ${LOCAL_BACKUP_DIR}/mysql.bak.gz
## example with two dumps for each table (.sql/.txt) for all databases
# for i in $(echo SHOW DATABASES | mysql --defaults-extra-file=/etc/mysql/debian.cnf -P 3306 \
# | egrep -v "^(Database|information_schema|performance_schema)" ); \
# do mkdir -p /home/mysqldump/${i} ; chown -RL mysql /home/mysqldump ; \
# mysqldump --defaults-extra-file=/etc/mysql/debian.cnf --force -P 3306 -Q --opt --events --hex-blob --skip-comments -T \
# /home/mysqldump/${i} ${i}; done
## example with compressed SQL dump for each databases
# mkdir -p /home/mysqldump/

### PostgreSQL
## example with pg_dumpall (warning: you need space in ~postgres)
# su - postgres -c "pg_dumpall > ~/pg.dump.bak"

## another method with gzip directly piped
# cd /var/lib/postgresql
# sudo -u postgres pg_dumpall | gzip > ${LOCAL_BACKUP_DIR}/pg.dump.bak.gz
# cd - > /dev/null
## example with all tables from MYBASE excepts TABLE1 and TABLE2
# pg_dump -p 5432 -h 127.0.0.1 -U USER --clean -F t --inserts -f ${LOCAL_BACKUP_DIR}/pg-backup.tar -t 'TABLE1' -t 'TABLE2' MYBASE
## example with only TABLE1 and TABLE2 from MYBASE
# pg_dump -p 5432 -h 127.0.0.1 -U USER --clean -F t --inserts -f ${LOCAL_BACKUP_DIR}/pg-backup.tar -T 'TABLE1' -T 'TABLE2' MYBASE
## MongoDB : example with mongodump
## don't forget to create use with read-only access

# if [ $? -eq 0 ]; then

# else
# echo "Error when flushing ES translog indexes."
