We are using a separate domain on the same webspace to backup two Joomla Sites. The Akeeba Solo domain runs on PHP 7.3.10 but the site we are trying to backup is a Joomla 3.5.0 version, running on PHP 5.6.4 and there we would like to backup only the database for now.
Unfortunately we get an error when doing so and I saw, that the error always occurs when the file size hits the 2GB mark on the webspace.
It seems we still have a lot of free space, so I'm ruling this out. I chmoded the "/backup" directory temporarily to 777 so this shouldn't be a problem.
Having the suspicion that the error occurs only when the backup file hits 2GB file size on the server, I tried to
use parts of maximal 1GB:
But this doesn't seem to work, as on the server, during the backup, the .sql file isn't cut apart, it just grows until it hits 2GB and Solo gives up on it.
Might be that I'm completely wrong with this impression and I would be happy if you could take a look at it.
P.S.: Sorry for the strange title, the forum cut of the rest of it, It was:
Getting: <Couldn't write to the SQL dump file <root>/backups/xxxxx.sql; check the temporary directory permissions and make sure you have enough disk space available.›
