If you are using Softaculous backups you may notice that Softaculous backups also the cache folders (wp-content/cache and wp-content/litespeed) and backups created by WordPress backup plugins (wp-content/updraft & wp-content/ai1wm-backup).
This significantly increases the size of Softaculous backup files. To exclude these folders from Softaculous backups SSH into your server and navigate to the following path:
Copy the existing file filter.txt to filter.php and edit it:
cp filter.txt filter.php nano filter.php
Uncomment the following part inside filter.php then add the path to the cache and backup folders:
$exclude_files = $softpath.'/wp-content/cache'; $exclude_files = $softpath.'/wp-content/litespeed'; $exclude_files = $softpath.'/wp-content/updraft'; $exclude_files = $softpath.'/wp-content/ai1wm-backups';
$exclude_files – This will be the list of files to be excluded calculated by Softaculous.
$softpath – This is the path of the backup installation.
Save the file and next time Softaculous backups run, these backup & cache folders will be excluded.
