How to do server cleanup by getting more space?

[AFN]

Besides the backups being located in /home/backup which I can delete from the control panel, what about the log files? Do the log files just keep growing in size or do they get replaced every so often so log files don't just keep growing in size?

When there are any backups, is the only place that backups are stored is in /home/backup or is there another place they are stored? If so where?

When I upload something via FTP, are those files stored anywhere temporarily on the server, if so how can I remove the temporary files? What about when I upload something via a third-party application such as through WordPress, are the files temporally stored somewhere on the server before being uploaded to the correct destination?

When I delete a website or a subdomain name from the control panel does it remove every trace of the website or subdomain name?

which log files do you mean? Log is normaly log, so you can remove them.

Normaly logrotate is setup, so the logs will be archived and older logs zipped.

When there are any backups, is the only place that backups are stored is in /home/backup or is there another place they are stored?

the backup will be placed in /backups, maybe you have in /home/backups a symlink that points to /backups.

When I upload something via FTP, are those files stored anywhere temporarily on the server, if so how can I remove the temporary files?

They will be uploaded directly to the folder without any temporary files.

What about when I upload something via a third-party application such as through WordPress, are the files temporally stored somewhere on the server before being uploaded to the correct destination?

Normaly not, but this manages your third-party extension, maybe they will create some temporary files.

When I delete a website or a subdomain name from the control panel does it remove every trace of the website or subdomain name?

yes, if you remove a user, the full /home/user directory will be removed. With all files, configurations and logs. Also backups should be removed.

It is better NOT to Delete logs but rather Truncate them...

You can run the below command and change minimum value shown in red to see what big files you have.

find / -type f -size +20M -exec ls -lh {} \; | awk '{ print $NF ": " $5 }'
