These backup scripts use rsync to minimize network load and creates incremental backups, preserving last four backups. For more info, read http://www.mikerubel.org/computers/rsync_snapshots/. Also recommend the article DAR differential backup mini-howto.

To install the cron job, run: 

$ sudo crontab -e

And add these lines according to your personal configuration: 

MAILTO=nomail@openkm.com
@weekly /root/backup.sh | tee -a /root/backup.log

Or, if you want to separate log reports by date: 

MAILTO=nomail@openkm.com
@weekly /root/backup.sh | tee /root/backup.$(date +\%Y.\%m.\%d_\%H.\%M.\%S).log

Nota clasica.png MAILTO may also be used to direct mail to multiple recipients by separating recipient users with a comma.

This script will export all databases from a MySQL installation: 

#!/bin/bash
#
## BEGIN CONFIG ##
MYSQL_PASS=""
DATABASE_EXP="/home/openkm/db"
## END CONFIG ##

rm -rf $DATABASE_EXP
mkdir -p $DATABASE_EXP

# Backup de MySQL
if [ -n "$MYSQL_PASS" ]; then
  MYSQL_DBS=$(mysqlshow -h localhost -u root -p$MYSQL_PASS | awk '(NR > 2) && (/[a-zA-Z0-9]+[ ]+[|]/) { print $2 }');
 
  for DB in $MYSQL_DBS; do
    if [[ $DB != "mysql" && $DB != "test" && $DB != "information_schema" && $DB != "performance_schema" ]]; then
      echo "* Backuping MySQL data from $DB..."
      mysqldump -h localhost -u root -p$MYSQL_PASS $DB > $DATABASE_EXP/mysql_$DB.sql
    fi
  done
fi

This script will export all databases from a PostgreSQL installation: 

#!/bin/bash
#
## BEGIN CONFIG ##
DATABASE_EXP="/home/openkm/db"
## END CONFIG ##

rm -rf $DATABASE_EXP
mkdir -p $DATABASE_EXP

# Backup de PostgreSQL
POSTGRESQL_DBS=$(su postgres -c "psql -l" | awk '(NR > 2) && (/[a-zA-Z0-9]+[ ]+[|]/) { print $1 }');

for DB in $POSTGRESQL_DBS ; do
  if [[ $DB != "template0" && $DB != "template1" && $DB != "postgres" ]]; then
    echo "* Backuping PostgreSQL data from $DB..."
    su postgres -c "pg_dump -Fc -b $DB" > $DATABASE_EXP/pg_$DB.dmp
  fi
done
