linux - 我的 Bacula 传输率非常低。我如何配置导演来改善这一点？

Question

我正在使用 bacula 创建一个基于云的解决方案来备份我们所有的服务器。我们有很多本地服务器，还有一些服务器在 AWS 和 OPENCLOUD 等云上。我看到备份的传输速率非常低(我说的是 400kbps/s)，小型文件系统每个大约 5/6GB...这让我很担心，因为我们正在测试这个客户端，使备份完整，最后2 小时完成，稍后我们将添加一些非常大的客户端(每个大约 500GB/1TB)以对它们进行完整备份

这是此客户端备份后打印的消息:

此消息显示了三台服务器，两台在本地，一台在 OpenCloud Cloudbased 主机上。鉴于结构，我们假设本地客户端将是所有备份中最慢的。但是在我们使用 iperf 命令测试连接后，我们看到以下内容:

我已经尝试过 despooling 选项，但我没有看到任何改进。有谁知道测试 bacula 性能的方法或脚本以及如何改进它？我可以尝试尽可能减少 FileSets 来备份我们真正需要的东西，但仍然有很多文件/gygas。

如果有帮助，这就是 Bacula-Dir.conf:

Director {                            # define myself
  Name = bacula-dir
  DIRport = 9101                # where we listen for UA connections
  DirAddress = 172.19.120.106
  QueryFile = "/etc/bacula/query.sql"
  WorkingDirectory = "/var/spool/bacula"
  PidDirectory = "/var/run"
  Maximum Concurrent Jobs = 10
  Password = "123456"         # Console password
  Messages = Daemon
  Heartbeat Interval = 1
}


Storage {
  Name = File
# Do not use "localhost" here
  Address = 172.19.120.106                # N.B. Use a fully qualified name here
  SDPort = 9103
  Password = "123456"
  Device = FileStorage
  Media Type = File
}

Pool {
  Name = File
  Pool Type = Backup
  Label Format = OpenCloud-
  Recycle = yes                       # Bacula can automatically recycle Volumes
  AutoPrune = yes                     # Prune expired volumes
  Volume Retention = 365 days         # one year
  Maximum Volume Bytes = 100G          # Limit Volume size to something reasonable
  Maximum Volumes = 350               # Limit number of Volumes in Pool
}

我认为此信息很有用，但如果任何情况下您需要某些服务的更多信息或需要我做某事，我很乐意提供所需的数据...我真的需要增加传输此解决方案的速率。

Answer 1

我意识到我正在使用 MySql 作为数据库后端，并且在处理大量插入数据时遇到了麻烦。所以我再次进行了全新安装，但这次使用 Postgresql 作为数据库，传输速率达到了近 40 mb/s。进步很大

我会将我自己的答案标记为正确的
