Hi,

Why did you think that backup can be done with services running?

Documentation clearly states that services MUST be stopped. What you are doing is not supported - hence may not work!

You can give it a try using unsupported way but you are doing it at your own risk and you are not covered by support if you damage repository!

Sidenotes:

I assume you have not read documentation otherwise you would not attept backup with services running. I suggest to read it and follow all steps as per instructions . There are few more things you need to be aware of like:
- cmd should be run with Admin rights (cmd.exe - run as administrator)
- you must have full rights to write to the drive (where you store your backup)
- there must be enough disk space to store backup (please consider that all reports stored in NewsStand are also part of that backup so it may be quite large backup file)

Thats it..

hope this helps

Hi,

Please follow the official documentation step by step https://help.qlik.com/en-US/nprinting/April2020/Content/NPrinting/DeployingQVNprinting/Backing-up-Qlik-NPrinting.htm and stop the services.

I think you want to keep the services active so users can continue to work with Qlik NPrinting, but this could generate inconsistent backup that is unuseful. Keeping only the Repository service running will warranty you that no other services will write data during the backup execution.

Best Regards,

Ruggero

Hi,

error is too generic and most importantly it is actually not NPrinitng but System OS error stating that your manager crashed:

did you check diskspace?
- do you know how much do you need
- how much space you have
- it would be safe to say that 50% of disk space should be sufficient on C drive
did you run it as an admin?
- this is absolutely compulsory
did you make sure there are no other backup files (zip files with the same name as your backup)
do you have any antivirus or antimalware software which may be causing issues or interrupting?
- if you do - switch it off or disable for the time of backup
  - long term you may setup antivirus exceptions so it does not stop other software trying to write to disk
Since it is a os error it should be logged in windows events
- what are the windows events logs saying?

Plenty things you can check - but ball is in your court as all abouve must be addressed and checked well

cheers

Hi,

I agree with @Lech_Miszkiewicz and I would like to ask the complete logs from the Windows command line starting from the command you ran to create the backup.

Best Regards,

Ruggero

Hi,

1) Disk space was available 50%

2) Yes, i have run cmd as admin

3) No other folder/file name was available with backup which i'm using. If incase i use same name it should over write.

4) Anti virus was not working/enabled.

5) windows application log files were attached.

Do you have NPrinintg installed on the same server as Qlik Sense (which is not supported)? I am just quessing here given the names of servers from log files.

Re: Nprinting Backup

Lech_Miszkiewicz — Tue, 16 Mar 2021 01:43:53 GMT

Also it seems like you are providing wrong password for your nprinting repository:

2021-03-15 23:29:24.315 UTC [6712] FATAL: password authentication failed for user "postgres"
2021-03-15 23:29:24.315 UTC [6712] DETAIL: Password does not match for user "postgres".
Connection matched pg_hba.conf line 82: "host all all ::1/128 md5"

Hi Lech,

If i used wrong password it should not connect at all, if this is the case can you please try from your end by giving wrong password you will see different error😉.

Same super password i have used for Qlik sense backup it is working fine without giving any error.

I think you should go deeper to get the possible solution.

Thanks in Advance!!!

Lech_Miszkiewicz — Tue, 16 Mar 2021 02:20:28 GMT

Can you tell me if this is running on the same server as Qlik Sense?
Also - this is in your logs and it is at the same run time (right before it crashes)... Error is clear-wrong password! This is where i stop quessing as first thing is to solve errors we can see in front of you!

Re: Nprinting Backup

Admin3 — Tue, 16 Mar 2021 02:51:42 GMT

Hi Lech,

No, we are using Nprinting in different server.

I too have small confusion with password, let me come back with latest updates.

can you please let me give some clarity postgre db password should be same for Qlik sense and Nprinting i'm i correct? if so password is correct.

Let me discuss with client and i will get back with latest update ASAP, at same time please get possible solution from your end.

Thanks in Advance!!!

Re: Nprinting Backup

Lech_Miszkiewicz — Tue, 16 Mar 2021 03:29:45 GMT

no passwords could be different! NPrinitng and Qlik Sense repositories are separate entities. They are different databases and whoever installed NPrinitng for you set that password up.

So it may happen that during installation you choose to use the same, but in my epxerience it rarely happens and usually is set as different passwords.

Answering your question:

can you please let me give some clarity postgre db password should be same for Qlik sense and Nprinting i'm i correct? - Answer: No, you are not correct. We cannot assume that they should be the same. They can be, but it depends if the person who installed NPrinting set it up so it is the same as QS.

Hi,

I agree with @Lech_Miszkiewicz, it seems a wrong password problem. I tried to run a backup on my installation without any issues. I inserted a wrong password and I had a similar error. As per Lech answer and Qlik NPrinting help site, the Repository password is the one inserted during the installation.

If you need a fast response time, please note that as customer you have signed a support contract and you can open a support ticket with a specific service level agreement.

Hello @Admin3

I notice that you keep posting the same or similar image.

What we really need is the NPrinting_Manager.log file. Please upload that here so we can review the full error message. The image you have been posting appears to crop out the key errors needed to understand and confirm what the actual issue is. The entire log file will give the full information we need.

kind regards...
