Data gzip or FTP problem?

I hope someone can help me on this little problem.

Bit of background first. I've dumped an Oracle database to a plain text file that I wish to gzip then transfer via ftp to another machine. The dump and gzip runs fine and if I gunzip the file while still in unix the file looks fine. The problems occur once the file is FTP to a windows NT machine. The transfer goes fine and I end up with a zipped file on Windows that I can unzip using Winzip. The unzipped file opens ok as well. All looks ok until you scroll down to around the 1000 record. After then all the text is screwed up with all the spacing wrong.

It appears the the FTP transfer may be causing problems. The file is 500K before gzip and around 18K after. If the file is transfered without any compression then it opens without any problems at all.

Does anyone have any ideas why it is doing this or any other possible reasons?

The file needs to be compressed because it is too large to send across a slow link that we are using and ftp is the only real option we have for an automated transfer.

Thanks.

CURLOPT_RESUME_FROM(3)					     curl_easy_setopt options					    CURLOPT_RESUME_FROM(3)

NAME
CURLOPT_RESUME_FROM - set a point to resume transfer from SYNOPSIS
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_RESUME_FROM, long from); DESCRIPTION
Pass a long as parameter. It contains the offset in number of bytes that you want the transfer to start from. Set this option to 0 to make the transfer start from the beginning (effectively disabling resume). For FTP, set this option to -1 to make the transfer start from the end of the target file (useful to continue an interrupted upload). When doing uploads with FTP, the resume position is where in the local/source file libcurl should try to resume the upload from and it will then append the source file to the remote target file. If you need to resume a transfer beyond the 2GB limit, use CURLOPT_RESUME_FROM_LARGE(3) instead. DEFAULT
0, not used PROTOCOLS
HTTP, FTP, SFTP, FILE EXAMPLE
CURL *curl = curl_easy_init(); if(curl) { curl_easy_setopt(curl, CURLOPT_URL, "ftp://example.com"); /* resume upload at byte index 200 */ curl_easy_setopt(curl, CURLOPT_RESUME_FROM, 200L); /* ask for upload */ curl_easy_setopt(curl, CURLOPT_UPLOAD, 1L); /* set total data amount to expect */ curl_easy_setopt(curl, CURLOPT_INFILESIZE, size_of_file); /* Perform the request */ curl_easy_perform(curl); } AVAILABILITY
Always RETURN VALUE
Returns CURLE_OK SEE ALSO
CURLOPT_RESUME_FROM_LARGE(3), CURLOPT_RANGE(3), CURLOPT_INFILESIZE(3), libcurl 7.54.0 February 03, 2016 CURLOPT_RESUME_FROM(3)
