【问题描述】：
我正在尝试备份 Solr 核心（Solr 8.1.1 处于独立模式）。我根据https://solr.apache.org/guide/8_1/index-replication.html#configuring-the-replicationhandler添加了复制请求处理程序@
当我运行 /solr/core/replication?command=backup 时，它会返回：
{
"responseHeader":{
"status":0,
"QTime":1},
"status":"OK"}
但是在运行 /solr/core/replication?command=details 时会返回：
...
"backup":[
"exception","/opt/solr-8.1.1/server/solr/core/data/restore.20200414231901420/_22sklw_Lucene50_0.tim"]}}
当我指定备份名称和位置（例如 /solr-backups/，它归 solr 用户所有）时，它从不创建任何文件。
我在这里做错了什么？如何让 solr 创建备份？
编辑： 这显示在日志文件中：

【问题讨论】：
-
Solr 日志是否显示任何有用的信息？
