Backup VDS and Dedicated Servers (Linux)

Below are two editions of the script for organizing data backup (backup) with VDS Linux. Both versions once a week, on Sundays, create a complete copy of all data and the MySQL database, and in the rest - only incremental archives. To run automatically, add a line like the following to the cron job manager:

10 0 * /root/bin/backup.sh >/dev/null 2>&1

For the scripts to work, the amount of free disk space in the system must exceed the size of the copied data. ободного места на диске в системе превышал размер копируемых данных.

Backup to FTP server

Initially assign values to several variables. DIRS - space-separated list of directories for backup. MUSER and MPASS - MySQL DBMS administrator data for the connection. FTPU and FTPP - user data for connecting to the FTP server. FTPS is the name of the FTP server. EMAILID - email address to which error reports will be sent. For correct operation, the ncftp client must be installed on the system:
#!/bin/sh

### System Setup ###
DIRS="/etc /home /var/www"
BACKUP=/tmp/backup.$$
NOW=$(date +"%d-%m-%Y")
INCFILE="/root/tar-inc-backup.dat"
DAY=$(date +"%a")
FULLBACKUP="Sun"

### MySQL Setup ###
MUSER="root"
MPASS="password"
MHOST="localhost"
MYSQL="$(which mysql)"
MYSQLDUMP="$(which mysqldump)"
GZIP="$(which gzip)"

### FTP server Setup ###
FTPD="/backup/incremental"
FTPU="user"
FTPP="password"
FTPS="ftp1.sim-networks.com"
NCFTP="$(which ncftpput)"

### Other stuff ###
EMAILID="user@yourdomain.com"

### Start Backup for file system ###
[ ! -d $BACKUP ] && mkdir -p $BACKUP || :

### See if we want to make a full backup ###
if [ "$DAY" == "$FULLBACKUP" ]; then
FTPD="/backup/full"
FILE="fs-full-$NOW.tar.gz"
tar -zcvf $BACKUP/$FILE $DIRS
else
i=$(date +"%Hh%Mm%Ss")
FILE="fs-i-$NOW-$i.tar.gz"
tar -g $INCFILE -zcvf $BACKUP/$FILE $DIRS
fi

### Start MySQL Backup ###
# Get all databases name
DBS="$($MYSQL -u $MUSER -h $MHOST -p$MPASS -Bse 'show databases')"
for db in $DBS
do
FILE=$BACKUP/mysql-$db.$NOW-$(date +"%T").gz
$MYSQLDUMP -u $MUSER -h $MHOST -p$MPASS $db | $GZIP -9 > $FILE
done

### Dump backup using FTP ###
#Start FTP backup using ncftp
ncftp -u"$FTPU" -p"$FTPP" $FTPS<<EOF
mkdir $FTPD
mkdir $FTPD/$NOW
cd $FTPD/$NOW
lcd $BACKUP
mput
quit
EOF

### Find out if ftp backup failed or not ###
if [ "$?" == "0" ]; then
rm -f $BACKUP/
else
T=/tmp/backup.fail
echo "Date: $(date)">$T
echo "Hostname: $(hostname)" >>$T
echo "Backup failed" >>$T
mail -s "BACKUP FAILED" "$EMAILID" <$T
rm -f $T
fi

Backup to local disk, NFS, iSCSI

Consider the variables that need to be configured. DIRS - space-separated list of directories for backup. MUSER and MPASS - MySQL DBMS administrator data for the connection. MNTD is the directory where the backup storage will be organized. This can be just a directory on the local hard drive, or an NFS or iSCSI network storage mounted at this point: #!/bin/sh

### System Setup ###
DIRS="/etc /home /var/www"
BACKUP=/tmp/backup.$$
NOW=$(date +"%d-%m-%Y")
INCFILE="/root/tar-inc-backup.dat"
DAY=$(date +"%a")
FULLBACKUP="Sun"

### MySQL Setup ###
MUSER="root"
MPASS="password"
MHOST="localhost"
MYSQL="$(which mysql)"
MYSQLDUMP="$(which mysqldump)"
GZIP="$(which gzip)"

### Datastore Setup ###
MNTD="/mnt"
DSD="backup/incremental"

### Start Backup for file system ###
[ ! -d $BACKUP ] && mkdir -p $BACKUP || :

### See if we want to make a full backup ###
if [ "$DAY" == "$FULLBACKUP" ]; then
DSD="backup/full"
FILE="fs-full-$NOW.tar.gz"
tar -zcvf $BACKUP/$FILE $DIRS
else
i=$(date +"%Hh%Mm%Ss")
FILE="fs-i-$NOW-$i.tar.gz"
tar -g $INCFILE -zcvf $BACKUP/$FILE $DIRS
fi

### Start MySQL Backup ###
# Get all databases name
DBS="$($MYSQL -u $MUSER -h $MHOST -p$MPASS -Bse 'show databases')"
for db in $DBS
do
FILE=$BACKUP/mysql-$db.$NOW-$(date +"%T").gz
$MYSQLDUMP -u $MUSER -h $MHOST -p$MPASS $db | $GZIP -9 > $FILE
done

mkdir -p $MNTD/$DSD/$NOW
mv -f $BACKUP/ $MNTD/$DSD/$NOW
rm -f $BACKUP/
