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。我们有很多服务器在本地,还有一些在云上,比如AWS和OPENCLOUD。我看到备份的传输速率非常低(我说的是400kps/s(,而小型FS的传输速率约为5/6GB。。。这让我很担心,因为我们正在用这些客户端进行测试,使备份完整,持续2小时才能完成,稍后我们将添加一些真正大的客户端(每个客户端约500GB/1TB(,以使它们的完整备份
这是备份此客户端后打印的消息:

此消息显示了三台服务器,其中两台在本地,一台在基于OpenCloud云的主机上。考虑到这种结构,我们假设onpremise客户端将是所有客户端中备份速度最慢的。但是,在我们使用iperf命令测试连接后,我们看到以下内容:

我已经尝试过放弃选择,但没有看到任何改善。有人知道测试bacula性能的方法或脚本以及如何改进它吗?我可以尽量减少文件集,只是为了备份我们真正需要的东西,但仍然有很多文件/gygas。
这是Bacula-Dir.conf,如果它有帮助的话:
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
}
我认为这些信息是有用的,但如果你需要更多的服务信息或需要我做点什么,我很乐意提供所需的数据。。。我真的需要提高这个解决方案的传输速率。
我已经意识到我使用MySql作为数据库后端,并且遇到了大量插入数据的问题。所以我再次进行了新的安装,但这次使用Postgresql作为数据库,传输速率几乎达到了40mb/s。大幅度提高
我会把我自己的答案标记为正确的
以下是关于Bacula调优的一些建议:
-
MySQL在Bacula中也受支持,但几乎总是需要根据您的发现进行调优。mysql自动调优脚本在这里非常有用。https://github.com/major/MySQLTuner-perl
-
PostgreSQL的伸缩性似乎要好得多,尤其是对于Bacula,但仍然需要调整。佩德罗在这里写了一本不错的指南:http://www.pedroliveira.pt/index.php/bacula-performance-tunnig-with-postgresql/
如果你还没有,最好加入Bacula用户邮件列表,在那里你可以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。
