Can you increasing the memory size in admin setting of plugin?

yes ...how much ?

Something of higher. No issues if you give more as server will take only the maximum allowed. After this, please wait for a day to see if cron is able to complete the file backup.

in my php.ini i have this
memory_limit : (Défaut : 64 Mo)
but i can 128Mo...

I need to change in 128 in my php.ini ??? or just in your plugin ?

In my plugin, there is a value in the settings page. Plz try that.

I hope you don't mind my jumping into this thread, but I had a pre-purchase question. Is it possible to use this plugin to move an Oxwall site to another host server? If so, how is it done (is there a script you run on the new host server that installs the site there from the backup copy)? Thanks!

1) You can have this plugin to create a site backup to move to other site. But if it's just for one time, I would recommend not to buy this plugin as you can get that done by cpanel backup.

2) There is no plugin option to restore back. You have to do that manually from the backup files.

in 120 it's ok.
 but i have not all folders in the .zip ...its ok ???

It should have all folders Sir. Can you share a screenshot of what you have in the zip file

voici...

Thanks for details. I will look on this.

and after teste,  archive .zip it's corupted or bad format ...

Yeah.. as you meantioned, the zip is not complete and so its corrupted

but what can i do ???

I am working on updating this plugin. Hopefully should be ready with more features and validations.
