linux – 完整的数据备份到Amazon S3

我使用的堆栈的相关部分是Node.js,MongoDB和Elasticsearch.

到目前为止,备份是通过转储整个MongoDB数据库,保存ES配置以及复制应用程序目录中的所有其他@L_607_5@(日志,代码本身等)来完成的.如果是本月的第一天,所有用户@L_607_5@也会被复制,否则只会添加自本月第一天起更改的@L_607_5@.然后将所有这些压缩到一个@L_607_5@中并@L_197_13@到Amazon S3.

数据大小已达到此进程占用过多磁盘空间的程度,并且无法一次性将@L_607_5@上载到S3.

这个大小的应用程序的下一个级别是什么(8 GB用户@L_607_5@,125,000个用户,3,000个其他文档,所有可在ES中搜索)？

我理解基于意见的问题在服务器故障上是不行的.我不是在征求意见,而是正常的,具有成本效益的解决方案适用于这种规模的应用.

更新：这些是我试图使用Duplicity的脚本和配置的相关部分.我正在使用Node来管理备份,因为它适合我现有的日志记录解决方案,已经安排在低活动时间内与其他所有@L_607_23@保持一致,并且可以在操作系统之间移植.

节点脚本,日志记录当然需要改进：

// Walks a directory recursively and returns a flat list of files
function walkDir() {};

// Node based rm -rf
function rmrf() {};

exec("mongodump --out dump",{ cwd: process.cwd() },function(err,dta) {
    if (err) return log("Error backing up: Couldn't dump MongoDB!");

    exec("sudo duply ats BACkup",function(err) {
        if (err) log("Error running Duplicity");
        else rmrf("dump");

        log("ExiTing.");

        process.exit();
    });
});

Duplicity配置：

Gpg_PW='GPG password'

TARGET='s3://s3-us-east-1.amazonaws.com/bucket'

TARGET_USER='KNown working AWS credentials'
TARGET_PASS='AWS secret key'

sourcE='/var/appdir'

MAX_AGE=6M

DUPL_PARAMS="$DUPL_PARAMS --exclude "/var/appdir/elasticsearch/data/**" "

我尝试过-s3-use-new-style,使用s3 http：//,然后设置S3_USE_SIGV4但没有运气.

这是我从Duplicity获得的日志：
