BackWPup hangs trying to create backup archive

Hello @fobvpadmin

can you please deselect:

Hi Andreas,

I deselected XML export and Plugin list file and reran the job. The script still hangs at the same point and has to be aborted (log file as given in my first post). Looking back at previous log files it is claer that the problem started after I updated to Worpress 5.5.3.
In case it helps I append the debug info. Note that I have set BackWPup maximum script execution time at 20 seconds. Thank you for your help

I have also now tried configuring the job in other ways:
A. database only
B. files only
The result is the same. It hangs at “Compressing files as ZipArchive. Please be patient, this may take a moment.” And then repaets endlessly until aborted.

@fobvpadmin
hmm could you try backup with Tar instead of Zip?
Thanks!

I switched to tar instaed of zip. It gave a few warning messages about file name format, like this:
WARNING: File name “wp-content/gallery/bulb-planting/cache/Bulb Planting at the north end of the park 2007.JPG-nggid017-ngg0dyn-0x250x100-00f0w011c010r110f110r010t010.JPG” is too long to be saved correctly in Tar archive!

But this time the job completed and the backup was uploaded to Dropbox OK.

That’s progress! Any suggestions on a workaround for the file name length issue? Ive not seen this before (with zip).

I’ve been trying to find what was causing the backup to fail when using zip: I’d prefer to use zip since it doesnt seem to fail through long file names. I looked in the hosting back-end at the folder wp-content/uploads/ I see a few folders related to backwpup. In particular I see *three* backwpup temp files. Should there be three? One of them gives Invalid backend configuration when I try to open it. Is there some cleaning up to be done here?

@fobvpadmin
Sorry about the delayed response, yes, you can remove all backwpup-temp folders, it will be automatically created when needed.
In some hosting environment, Zip archive can cause issues, that depends on host too in my experience.
