Periodic FTP Backup is Not Working

[axvaster]

Hi,

We set all backup method (FTP, SSH, Local) on Nagios XI (5.6.2); and periodic FTP backup works fine until last month.

I checked the permissions, FTP server disk usage; there seems no permission or disk issue on the FTP server.

Also tested functions by clicking buttons (test upload... etc) all works fine, no error messages.

The only problem is that it just "can not automatically" do FTP backup job.

Is there any options that I can check to find out this root cause?

P.S. I would PM profile when any replies available.

Thanks!

Hi,

Let's take a closer look at the log files and to see what's happening. You mentioned that it was working fine until last month. Did you make any recent changes to the server?

Run the following tail command:

Code: Select all

 tail -F /var/log/httpd/error_log /var/log/httpd/ssl_error_log /usr/local/nagiosxi/var/cmdsubsys.log /usr/local/nagiosxi/var/components/scheduledbackups.l

Then force a FTP scheduled backup to run and after it's completed or failed, post the full output from that command.

Also, please send us the system profile to review the other logs.

To send us your system profile.
Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button

Thanks!
Benjamin

..........^C

2. how to force a FTP "scheduled" backup? I didn't find the button to execute; but the test uploads.

3. Going to PM you profile.zip

HI @axvaster,

Got the profile. There isn't a button in the user interface to force a scheduled backup, I normally set it a few minutes in advance and wait to test this.

This is a large system, and it may be timing out or it's not able to complete the backup archive. Please post the output of the following command to check the permissions.

Code: Select all

ls -la /store/backups/nagiosxi

Then run the following commands to generate a backup from the command line and the time required.

Code: Select all

 cd /usr/local/nagiosxi/scripts
time ./backup_xi.sh

If you haven't done so already, I would recommend optimizing the PHP settings on this system. After making those changes, please try testing it again.
