在 Aerospike 中恢复备份

Question

我正在尝试从 aerospike 恢复备份，但出现此错误：

2016-01-26 21:55:47 GMT [INF] [20675] Starting restore to 127.0.0.1:3000 (bins: [all], sets: [all]) from backup.asb

如何解决这个问题？

备份和恢复服务器具有相同版本的 aerospike（Aerospike 社区版 build 3.7.2）

这是备份文件的前 42 行：

Answer 1

前几行，直到您看到“3.1 版”的那一行是无效的备份。

.... 127.0.0.1:3000 的备份（命名空间：test，set：[all]，bins： [all]) 到 [stdout]

根据您分享的第一行，您似乎正在使用“stdout”作为输出文件名。这将捕获备份命令的所有输出，其中还会打印一些运行时信息。这会混淆恢复命令，因为备份文件不是预期的格式。

因此，请不要将标准输出重定向到备份文件。如果要捕获备份命令的标准输出，可以将其重定向到与备份文件不同的文件。
