Hello!
I've been using Cobian Backup for years, mostly since the encryption kind of malware got common. Since some kind of attacks could infect network shares, I've been using FTP backups. As I remember, everything was working fine till maybe 2-3 years ago.
The issue I'm facing now is on a Windows Server 2012 R2 using Cobian Reflector to backup to a NAS with FTP Server enabled. I was using Cobian Backup 11 before, but facing same kind of problems, so I tried Reflector... but with no luck. Nothing was changed on the NAS, as far as I know, and on Windows Server only the regular Windows updates.
The software is configured to make incremental backups and use a specific day to a full backup. The full backup always works fine, but the incremental fails most of times (not always) with the following errors:

2022-03-17 21:22:10 The backup has ended. There are errors. Consult the log file.
======================================================================
From over a million filesm wich should result on at least between 1.000 to 3.000 new or modifyed files per day, it only backed up 100 (today). Some times it backs up only 3 or for files, some times none... and some times it complets the task (incremental) with no errors.
On saturday, the day I specified for a full backup, it completes the task with no errors.
I tried to reset the NAS device. The first backup (complete) was OK; The second gave that kind of error, but the next days (maybe 2 weeks) were all ok. But then it started to give this error again.
I was using Reflector before I done the reset to NAS. But already before that, I was receiving errors with Cobian Backup 11. Not the same specific error, but the result was the same: only few files or none were backed up on incremental; everything ok on full backup.
I only know the basics about FTP. I've been using the same settings for years:
- The software is installed as a service with local system account;
- The FTP destination is configured with default settings, just checked the passive mode (whatever that means);
- The backup folder is set (COPIAS);
- The test works fine with no errors (the test folder or file is created on destination);
- The NAS device is a Netgear ReadyNAS with firmware 6.10.7 (latest) and there are not much FTP settings I can change on it.
This is not the only problem I have with FTP backup. Other errors regarding time outs, permitions, login issues, I solved it by changing the backup task destination to a network share (the same NAS device and the same FTP folder). I think this can be a solution, but I don't know if it is secure enough compared to FTP. The inttention of the backup is to have all files secured in case of a ransomware attack or accidental delete.
Can someone help me with this problem?
Thanks in advance!
