王爱东 · 发表于 2020-2-14 14:45:44

用户在使用系统后，为保证安全，需要随时对服务端文件备份，最近遇见一个问题，自动备份后都备份不完整，经过排查，发现在备份拷贝数据的时候，报告错误。

个别文件拷贝的时候提示系统资源不足。这种拷贝直接用的windows 的 copy 命令。

然后我们使用其他的拷贝工具，又能成功的拷贝。

可以使用fastcopy进行拷贝备份服务端文件。只需要把批处理中的copy 替换成fastcopy文件就行。按照参数传递即可。

命令行示例：fastcopy.exe /cmd=sync /auto_close /acl "D:\web" /to="E:\web_bak"

1. Please use space character(' ') as separator(not semicolon).
If filename contains space character, please enclose with dobule quotation marks.
Ex) fastopy.exe C:\Windows "C:\Program Files" /to="D:\Backup Folder\"

2. If you want to wait to finish, please use start /wait command.
Ex) start /wait fastcopy.exe [/options]...
Supported options are as follows. (Please don't put space characters before and behind "=")

/cmd=(noexist_only|diff|update|sync|force_copy|move|delete) ... Specify operation mode.
(By default, diff mode is used. If delete mode is specified, then "/to=" option isn't used.)

/auto_close ... Close automatically after execution is finished with no errors.

/force_close ... Close automatically and forcedly after execution is finished.

/open_window ... Don't stored in the task tray.

/estimate ... Estimate complete time.

/no_exec ... Don't start to execute.

/no_confirm_del ... Don't confirm before deleting.
