Incremental backup error (not always, but most of times)

Post by xikilin »

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!

As far I have read, the incremental backup does not work on FTP, only full. I quote the post where Luis says this.

I think you misunderstood my post...

FTP is the destination, not the source.
Source: D:\PARTILHA
Destination: FTP 192.168.100.250/COPIAS

I have this working fine on another machine (source: Local Folder; destination: FTP) with Cobian Backup v11. And had this kind of backup working fine on few other machines. Some of them started to give some errors and failing the tasks. I just can't understand why. The solution I found was to change from FTP to NETWORK destination.

I think FTP worked if the start was set to application instead of service, but in this case I need it to be as service.

There is an update about this, I haven't realized before:
The total files to backup is over 2,5 Million. Every time it fails, it never reaches all the files. Sometimes 1,3 million; sometimes 1,5 million, sometimes 1,7 million.

I can't do it now (late night), but I will try to upload some other logs tomorrow.

Thank you for answering!

Sorry, I misunderstood the original post. Then things to check:

* Are you using the archive attribute?
* Are you cleaning the archive attribute?

Please note that when errors, sometimes a few files are copied.



After these backups, there were 2 weeks with no errors. 11 incremental backups (2 of them complete) with no errors. The 12th one, incremental, got those "known" errors gain (a lot of them); but the 13th one, also incremental, finished with no errors.

Meanwhie, few incremental were finishing ok with no errors, but most of them always with errors. The complete ones (on saturdays) where always ok with no errors.

But now, the last complete backup (this weekend), also gave 4 errors:

I did a hdd check to server and NAS and they report no problems. Both Server and NAS have a 2TB HDD. Server has about 1TB free space and NAS about 500GB free space.

Is anyone familiar with these kind of errors (I believe they are know FTP errors)? Those error codes may help...?

Anyway, I'll appreciate any help.

Thank you!

Re: Incremental backup error (not always, but most of times)

Post by Tecland »

I am having the same issue, maybe because the backup is incremental? I mean, having the same configuration as you, my full backups are ok with no errors, but the incremental ones have always a lot.

Thank you

The errors you are getting "Control channel unexpectedly closed" means that the server has disconnected the client. Look at the server log to find out the cause. Perhaps timeout?
