貼在這邊紀錄一下 有空的人可以試試看

    這是小弟用 php 寫的備份 script
    只需要依個人所需更改 $SOURCE_DIR 和 $EXCLUDE_D 最後再 chmod +x 就可以了。
    如果要放 crontab,將 $ask = strtolower(read());
    拿掉就可以了



    #!/usr/bin/php -q
    <?php
    //Change The following two variables
    $SOURCE_DIR = "/bin /boot /etc /home /lib /mnt /opt /root /sbin /tmp /usr /var";
    $EXCLUDE_D = "/home/benny/mnt /usr/portage/distfiles";
    $DEST_DIR = "/misc/backup";

    //Stop here unless you know what you're doing
    $EXCLUDE_DIR = explode(" ",$EXCLUDE_D);
    $DATE = date("Y-m-d");
    $FILE = "BACKUP-".$DATE.".tgz";
    for ( $i = 0; $i < count($EXCLUDE_DIR); $i++ ) {
    if ( !$EXCLUDE ) { $EXCLUDE = " --exclude=".$EXCLUDE_DIR[$i]; }
    else { $EXCLUDE = $EXCLUDE." --exclude=".$EXCLUDE_DIR[$i]; }
    }
    $BACKUP = "tar -zcvf ".$DEST_DIR."/".$FILE." ".$SOURCE_DIR.$EXCLUDE;
    function read() {
    $fp = fopen("php://stdin","r");
    $input = fgets($fp,255);
    fclose($fp);
    return eregi_replace("\n","",$input);
    }
    echo "=-= System Backup =-=\nDESTINATION PATH: "
    .$DEST_DIR."\nFILE: ".$FILE.
    "\nExcluding: $EXCLUDE_D\n".
    "\nProceed? [Y/n]: ";

    $ask = strtolower(read());
    if ( !$ask ) { $ask = "y"; }
    if ( $ask == "y" ) {
    echo "System Backup will start within 5 Secs\n";
    for ( $i=0; $i<5; $i++ ) {
    echo 5-$i."\n";
    sleep(1);
    }
    echo "Initializing System Backup...\n";
    shell_exec("echo Starting @ `date` >> backup.log");
    shell_exec("echo Filename: $FILE >> backup.log");
    shell_exec("$BACKUP");
    shell_exec("echo Completed @ `date` >> backup.log");
    }
    else { echo "Aborted!\n"; }
    ?>
