Hello, good morning, I am having a problem for which I cannot find a solution and for several weeks I have been trying to solve it.
A little history: I have a Windows Server 2016 with Cobian Backup running for several years. This Cobian Backup takes files from different locations on the network, for example \\server\backuplocation and copies them to two paths, a local one (for example G:\Backup), and then to a path via FTP (for example 10.100. 10.20/Backup).
Cobian Backup has never given me any problems, and the copy has always been performed successfully, both to the local drive and to the FTP.
In December I finally decided to install Cobian Reflector on the same OS where CB was running, disabling the CB services so that they cannot run simultaneously. I imported the task list into the new Reflector and everything started working automatically with the same settings and preferences as always.
Now the problem: while everything seems to work fine, when Reflector tries to copy a folder with several backup files to the FTP repository it usually manages to copy one or some of several files and then fails for the remaining files. The files are usually several GB (above 100 GB), but I verified that this also happens with files of a few MB. It would seem that the failure only happens when the copy job will transfer more than 1 file. I have attached a fragment of the log below.
I can't understand why this problem doesn't happen with Cobian Backup but it does with Cobian Reflector.
I have verified different things:
- file/folder names, no spaces or invalid characters.
- firewall between the two hosts
- connection timeout (I increased it to a large value without success)
- number of simultaneous connections (I increased it)
