When I got 33% of the back up, I have the next error (I send u an image as well) :

El respaldo falló

La operación de respaldo se ha parado porque se detectó un error.
El último mensaje de error fue:

AJAX Loading Error
HTTP Status: 503 (Backend fetch failed)
Internal status: error
XHR ReadyState: 4
Raw server response:
Error 503 Backend fetch failed
Backend fetch failed

It seems you are backing up Jotcache table record.
Can you please exclude that table records from the archive and try again?
Since it's just cached data, there is no need to during a restore

it seems you have a lot of duplicated tables.
For example there is #__content_ok and #__content_frontpage_ok, please double check the table that are actually backed up.

It seems that the backup gets killed before it can run another step.
Please try to run the configuration wizard again and then take another backup. The wizard will try to understand what's the optimal execution time.
If you still get a backup error, please try to manually set these values inside the configuration page:
Maximum execution time: 3 seconds
Minimum execution time: 5 seconds
Runtime bias: 75

Yes, minimum is greater than the maximum, that's not a typo
Backup speed will be lowered, but you should avoid timeout issues.

Ok, finally I got the backup. However, while it was running, it stopped 5 or 6 times with the same error HTTP Status: 503 (Backend fetch failed), but the back up went on every time. Is that ok? I send u the log again. It is 12 MB size.

Your server is killing a backup that takes too long.
Let's try to tweak it and backup only the useful stuff.
First of all I can see you are backing up sh404sef url cache table; you can exclude it.
Then in the scanner engine, use the option Large site scanner.

This should help, if not please post here and we will try another workaround
