Question

我在服务器上运行以下脚本：

#!/bin/bash
# System + MySQL backup script
# Full backup day - Fri (rest of the day do incremental backup)
# Copyright (c) 2005-2006 nixCraft <http://www.cyberciti.biz/fb/>
# This script is licensed under GNU GPL version 2.0 or above
# Automatically generated by http://bash.cyberciti.biz/backup/wizard-ftp-script.php
# ---------------------------------------------------------------------

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

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

### FTP server Setup ###
FTPD="/backup/incremental"
FTPU="xxx"
FTPP="xxx"
FTPS="xxx"
NCFTP="$(which ncftpput)"

### Other stuff ###
EMAILID="xxx"

### 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/*
 T=/tmp/backup.pass
 echo "Date: $(date)">$T
 echo "Hostname: $(hostname)" >>$T
 echo "Backup passed" >>$T
 mail  -s "BACKUP PASSED" "$EMAILID" <$T
 rm -f $T
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

一切都运行良好，除了它总是告诉我一切顺利，即使远程ftp服务器已满。有人可以帮我改变这个，所以当远程服务器已满时，它会给我一个错误吗？另外，有没有办法删除旧备份？

谢谢，丹尼尔
