java将文件从Azure文件共享目录移动到unix目录和备份目录(在Azure文件共享中)
需要将Azure文件共享上的目录中的所有文件移动到Unix目录。移动后,在备份目录中备份这些文件
我写了一个方法,根据文件名将文件从Azure文件共享目录移动到unix目录。但我需要更改它,以便它移动所有文件并进行备份。 源目录地址如下所示:- Z:\Business 已创建备份目录,该目录为:- Z:\Business\Backup 业务下没有子目录,只有文件和名称以Data_files_yyyymmdd开头
第二步, 需要将所有文件从目录移动到unix目录
编辑:1- 我对代码进行了一些编辑,因为我在一个工具中运行它。 并将代码称为:- 主代码(AzureStorageConnectionString)
但我得到的错误是:- [错误]com。微软蔚蓝色的存储StorageException:指定的资源名称包含无效字符。 我试图把它修好,但没能修好。 我尝试将backupFileShareName更改为不同的名称,如下所示,但两者都不起作用。 尝试1)静态字符串backupFileShareName=“Business/Backup”; 尝试2)静态字符串backupFileShareName=“Backup”

听起来你想将Azure文件共享中的所有文件下载到本地目录,并将它们备份到另一个Azure文件共享
以下是我的Azure Storage SDK v8 for Java示例代码(我看到您使用了相同的SDK版本),以满足您的需要
我已经在本地环境中测试了它
希望能有帮助
更新:
有关资源名称中使用的无效字符的问题,请参考Naming and Referencing Shares, Directories, Files, and Metadata了解它,并通过编码修复它,例如使用
/
的url编码
