T-REX does full backups of each server nightly and weekly using the Linode Backup Service
Linode Backup Service is a simple and reliable on-site backup solution for your cloud server. This seamlessly integrated system performs backups without interruption.
T-REX staff advise strongly against using backup plugins because while they may *store* the backups off-site, most of them create a temporary file on the server prior to sending it offsite. Each web store is allocated enough disk space for that store. Any additional disk space usage such as individual store backups performed by store owners will cause the store to run into disk quota issues and can cause database corruption.
If your database or website becomes corrupt due to a plugin that you installed, you may be responsible for costs associated with repairing or restoring your store.
