Backup por FTP

Los backup o copias de seguridad son la base del mantenimiento de un sitio web… gestionarlos no suele ser complejo aunque pocas veces se trabaja de forma completa para conseguirlos. Hace unos días encontré un script para Linux que te permite realizar backups completos e incrementales de una forma sencilla, y la verdad es que está bastante bien.

#!/bin/bash
# File System Backups via FTP with MySQL Databases
# Copyright (c) 2017 Mitchell Krog 
# ---------------------------------------------------------------------
# Save as /bin/ftpbackup.sh and make executable
# chmod +x /bin/ftpbackup.sh
# Requires NCFTP to be installed
# sudo apt-get install ncftp
# Full backup day Mondays (otherwise incremental backups are done) cen be changed below
# Automatic cleaning up of anything older than 35 days (can be changed to suit you)
### Your System Settings ###
DIRS="/bin /etc /home /var/local /usr/local/bin /usr/lib /var/www"
BACKUP=/tmp/backup.$$
NOW=$(date +"%Y-%m-%d")
INCFILE="/root/tar-inc-backup.dat"
DAY=$(date +"%a")
FULLBACKUP="Mon"
### Your MySQL Settings ###
MUSER="root"
MPASS="yourpassword"
MHOST="localhost"
MYSQL="$(which mysql)"
MYSQLDUMP="$(which mysqldump)"
GZIP="$(which gzip)"
### Your FTP server Settings ###
FTPD="//backup-directory-on-ftp-server"
FTPU="ftp-username"
FTPP="ftp-password"
FTPS="ftp.server.address"
NCFTP="$(which ncftpput)"
### Your Email Address ###
EMAILID="youremail@yourdomain.com"
### Backup our DPKG Software List ###
dpkg --get-selections > /etc/installed-software-dpkg.log
### Start the Backup for the file system ###
[ ! -d $BACKUP ] && mkdir -p $BACKUP || :
### Check if we want to make a full or incremental backup ###
if [ "$DAY" == "$FULLBACKUP" ]; then
  FTPD="//full-backups"
  FILE="MyServer-fs-full-$NOW.tar.gz"
  tar -zcvf $BACKUP/$FILE $DIRS
else
  i=$(date +"%Hh%Mm%Ss")
  FILE="MyServer-fs-incremental-$NOW-$i.tar.gz"
  tar -g $INCFILE -zcvf $BACKUP/$FILE $DIRS
fi
### Start the MySQL Database Backups ###
### Get all the MySQL databases names
DBS="$($MYSQL -u $MUSER -h $MHOST -p$MPASS -Bse 'show databases')"
for db in $DBS
do
 FILE=$BACKUP/mysql-$db.gz
 $MYSQLDUMP --single-transaction -u $MUSER -h $MHOST -p$MPASS $db | $GZIP -9 > $FILE
done
### Check the Date for Old Files on FTP to Delete
REMDATE=$(date --date="35 days ago" +%Y-%m-%d)
### Start the FTP backup using ncftp
ncftp -u"$FTPU" -p"$FTPP" $FTPS< $T
 echo "Hostname: $(hostname)" >>$T
 echo "Backup failed" >>$T
 mail  -s "MYSERVER - BACKUP FAILED" "$EMAILID" < $T
 rm -f $T
fi

Aunque hay que hacer algunos cambios para adaptarlo a tu servidor, puede ser muy básico usarlo como plantilla para crear tu sistema de backups completo e incremental.
