Corrupted data trying to uncompress zip sent by Cobian

[klopez]

Hi, I have a problem in many servers that send zip backups to an ftp server.

All servers send the zip backups directly to the ftp server, i mean, I compress the backup manually with a .bat.
Cobian doesn't compress anything, only sends the backup zip.

When i try to uncompress the backup zip i've sent, it says that the zip has corrupted data. But when i send the backup zip through Filezilla, the uncompress is ok and there's no errors.

Any idea of what's happening with my Cobian servers?

Which version are you using? In the first version up to 1.3 if I remember it correctly some files where uploaded in ASCII mode.

[klopez]

I'm using the last version: 2.6.55

[cobian]

Then that shouldn't be a problem. Do you see some difference in size?

[klopez]

No, the task says that size is 217 MB. It's exactly the same, the backup.zip on Filezilla is 216,07 MB

[cobian]

What kind of server are you using?

[klopez]

I have servers with Windows Server 2019 and Windows Server 2016. The corrupted data error appears in some of them, not all.

[cobian]

So it's IIS you are using I assume?

[klopez]

No, I use Apache, but i'm doing a backup of a mysql database. I save the .sql with and then i compress them in the .zip

[cobian]

But Apache is not a FTP server, but a Web Server. If you are not using IIS as the FTP server, then which one is being used?
