问题描述

我正在使用 bacula 创建一个基于云的解决方案,以备份我们所有的服务器。我们在本地有很多服务器,还有一些在 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)和每个大约 5/6GB 的小 FS ......这让我担心,因为我们正在使用这个客户端进行测试,使备份完整持续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)来对它们进行完整备份

这是备份此客户端后打印的消息:

此消息显示三台服务器,两台在本地服务器上,一台在基于 OpenCloud 云的主机上。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:

我已经尝试过去假脱机选项,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文件集,以备份我们真正需要的东西,但仍然是很多文件/gygas。

如果有帮助,这是 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
}

我认为这些信息很有用,但是如果您需要更多有关某些服务的信息或需要我做某事,我很乐意提供所需的数据......我真的需要提高这个的传输率解决方案。

解决方案


以下是关于 Bacula 调音的一些建议:

  1. Bacula 也支持 MySQL,但几乎总是需要根据您的发现进行调整。自动 mysql 调优脚本在这里非常有用。 https://github.com/major/MySQLTuner-perl

  2. PostgreSQL 似乎确实可以更好地扩展,尤其是对于 Bacula,但仍然需要调整。佩德罗在这里写了一个很好的指南:http ://www.pedroliveira.pt/index.php/bacula-performance-tunnig-with-postgresql/

而且,如果您还没有,加入 Bacula 用户邮件列表也是一个好主意,您可以在其中搜索档案并获得其他 Bacula 问题的帮助。https://www.bacula.org/support/email-lists/

最后,如果您有订阅,Bacula Systems 可以提供调整指导。
