1 click upgrade taking 7 hours to backup

[murdoc_tcc]

Hi, so Im having major issues when I click on 1 click upgrade, and I start the process, then it starts to back up.

 

The backup process takes about 7 hours, and at the end everything just fails and the upgrade doesn't occur, Please Prestashop bosses, tell me what to do or a step by step noob friendly how to do something alternative.

 

Currently sitting at version 1.7.4.2

Long backup process is often caused by the following factors:

- large number of images, but images rather don't need to be backed up, risk of loosing the images is quite low, so this option ca be safely turned off in the upgrade module

- some additional non-prestashop subfolder inside shop's main folder, sometimes some other software is installed in a subfolder, it's better to put it in a subdomain

- large database, it can be bloated by statistics, if the shop has many visitors, there can be millions of rows, that are not much needed any more

I recommend using the Tidy module before the upgrade to clean up the database, I had cases where the backup took a minute, when it was more than half an hour before the cleanup.

In my case slow upgrade was caused by some wordpress website installed into subfolders, because autoupgrade module backup everything into prestashop folder and there's no option to exclude them.
