Confluence can't backup

[Tony Montana]

Hi! I'm really crying. I have Server with confluence. 8Gb RAM, 200GB HDD (100GB FREE). /var/mysql have size 9.8Gb (s0 small), but I anyway can't xml backup. WHYYYY?  How much does it need? 100-200-500 RAM???

It is nginx issue. Just close backup page after click backup button. Backup anyway will be created. One sample.

Try to see if you can switch it to downloading through the UI and see if you can obtain an XML file from there.

Here's the instructions:

Hi, Ben. Thx for the answer. There isn't any resolve my problem. 'cause I increase my RAM to 23GB and backup is succefull. But! I have 2 parts of backup. *-1.zip and *-2.zip ANd how i can restore it?

[Benjamin]

That's good to hear. I have never heard of having two zip files. Could it be possible that it was backed up multiple times?

See the time stamps and zip file size.

Hi, Ben! Thx for the Answer!.

I absolutely press the backup button once.

And I get two files. This is repeatly behavior.  For example:

xmlexport-20220331-215009-1.zip.
xmlexport-20220331-215108-2.zip.
Each 760MB

Maybe it's a bug?  May be, but I defenitly don't know how  fix it.

HI @Tony Montana ,

What directly is set for where your xml back ups would be back up. Does that directory have sufficient space?

Also, check your confluence logs to see what is the error when you execute an XML back up. 

IF you are performing a backup as a job, make sure it's enabled as well.

And I tried to create without attachs. 

2. Without any errors connected to backup proccess in tacalina or atlassian confluence log. Backup file just isnt present to any folder.

3. It's a manual backup

I have a similar issue. I only clicked the backup button once, but it seems that two backup processes are running:

ls -ltr
total 8
drwxr-x--- 2 confluence confluence 4096 Aug 14 08:54 xmlexport-20230814-085355-1
drwxr-x--- 2 confluence confluence 4096 Aug 14 09:08 xmlexport-20230814-090824-2

How can this happen?

Best regards,
Karsten
