Title: [Plugin: WordPress Backup to Dropbox] Memory issues Last modified: August 19, 2016 --- # [Plugin: WordPress Backup to Dropbox] Memory issues * [sangatpedas](https://wordpress.org/support/users/sangatpedas/) * (@sangatpedas) * [15 years, 1 month ago](https://wordpress.org/support/topic/plugin-wordpress-backup-to-dropbox-memory-issues/) * Hi, * As soon as I installed the plugin and started the first backup I got an email from my webhost about processes using excessive amounts of memory. * Please check my post about the issue: [http://sangatpedas.com/free-memory-eating-wordpress-backup-to-dropbox-plugin/](http://sangatpedas.com/free-memory-eating-wordpress-backup-to-dropbox-plugin/) * [http://wordpress.org/extend/plugins/wordpress-backup-to-dropbox/](http://wordpress.org/extend/plugins/wordpress-backup-to-dropbox/) Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Contributor [Michael De Wildt](https://wordpress.org/support/users/michaeldewildt/) * (@michaeldewildt) * [15 years, 1 month ago](https://wordpress.org/support/topic/plugin-wordpress-backup-to-dropbox-memory-issues/#post-2070861) * Gday sangatpedas, * Memory usage is something that I am trying to address. The problem is, for large websites like yours, a significant amount of memory is needed to archive the backup and upload it to Dropbox. * I posed a fair bit of info on the core of the problem here –
