All plans include free 50 GB of backup storage with a 31 day retention. You can optionally purchase more storage when needed.
These backup are incremental and do not use as much storage as regular cPanel backups. Those backups are compressed tar.gz files consisting of all your account data and not the changes you have made day to day. We do still provide unlimited regular cPanel backups that do not count toward your free 50 GB backup storage however we only retain 7 days worth of daily backups and 12 weeks of weekly backups.
