相信很多個(gè)人網(wǎng)站的站長，或者是獨(dú)立Blog的博主，都有著備份數(shù)據(jù)庫這樣一個(gè)需求。當(dāng)然WordPress這樣插件非常豐富的Blog系統(tǒng)有好多能幫你完成這項(xiàng)任務(wù)的插件。如果您需要自己親手來備份數(shù)據(jù)庫的話，我貼一個(gè)Mysql自動(dòng)備份腳本供大家參考，在國外網(wǎng)站上看到的，還是不錯(cuò)，實(shí)現(xiàn)了定期備份Mysql數(shù)據(jù)庫，并且可以選在在每周的一天做指定目錄下文件的全面?zhèn)浞?，備份文件自?dòng)上傳到你指定的FTP上，保證了備份的可靠性。如果只是把數(shù)據(jù)庫備份在和數(shù)據(jù)庫一起，我想意義也不是特別大了。

### System Setup ###
##備份本件本地目錄##
DIRS="/home/xxxx"
BACKUP=/tmp/backup.$$
##日期格式可以自己調(diào)節(jié)##
NOW=$(date +"%Y-%m-%d")
INCFILE="/home/xxxx"
DAY=$(date +"%u")
##星期天完全備份可以自己調(diào)節(jié)##
FULLBACKUP="7"

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

### FTP server Setup ###
##增量備份路徑##
FTPD="/backup/xxxx/incremental"
FTPU="chaos"
FTPP="password"
FTPS="xxx.xxx.com"

### Other stuff ###
EMAILID="chaos@diablo.net"

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

### See if we want to make a full backup ###
if [ "$DAY" == "$FULLBACKUP" ]; then
##完全備份路徑##
FTPD="/backup/xxxx/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
##備份所有數(shù)據(jù)庫可自行調(diào)整或備份指定數(shù)據(jù)庫##
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 lftp
##ubuntu上可以使用ncftp 自行調(diào)節(jié)##
#ncftp -u"$FTPU" -p"$FTPP" $FTPS<<EOF
lftp -u $FTPU,$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
