在低带宽情况下（成功）上传大文件的最佳方法？
我的工作包括每天将存档文件（10-25mb）上传到 FTP 服务器（使用cuteFTP）。问题是上传是从偏远村庄完成的，那里 USB 数据卡的带宽非常差。结果，上传的多个文件被损坏。
两个问题：
有什么办法可以更有效的上传文件吗？除了 CuteFTP 之外还有什么模式需要更少的带宽？
还有什么方法可以通过使用 CRC 等动态检查哪些文件已正确上传，以便上传者可以在上传时出现数据损坏时立即重新上传？
我对 PHP 和 PHP 比较熟悉。 MySQL。
任何建议...谢谢！
问候， 数据库
My work involves uploading archived files (10-25mb) onto a FTP server (using cuteFTP) on daily basis. Problem is that uploading is done from remote villages where USB datacards give very poor bandwidth. As a result, several files that are uploaded get corrupted.
Two questions:
Is there any way to upload the files more effectively? Any mode apart from CuteFTP that takes lesser bandwidth?
Also is there any way to check which files have been uploaded correctly by using CRC etc on the fly so that uploader can immediately reupload if there is data corruption while uploading?
I am relatively comfortable with PHP & MySQL.
Any suggestions ... Thanks !
Regards,
DB

是否可以在发送之前拆分文件？许多 ZIP 压缩实用程序都支持这一点。
Would it be possible to split the files before sending? Many ZIP compression utilities support this.
