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。
