An enterprise-class cloud backup solution must include an on-premises cache, to mitigate any issues due to inconsistent Internet connectivity.<ref>Vendor Landscape Storyboard: Cloud Backup. InfoTech Research Group Research, July 2011. p. 4</ref>

Hybrid cloud backup works by storing data to local disk so that the backup can be captured at high speed, and then either the backup software or a [[Cloud Storage Gateway|D2D2C (Disk to Disk to Cloud) appliance]] encrypts and transmits data to a service provider. This adds protection against local

Hybrid cloud backup is an approach combining local backup for fast backup and restore, along with off-site backup for protection against local disasters.<ref>{{cite news|last1=Taylor|first1=Martin|title=Cloud backup options: Pure cloud vs hybrid cloud backup|url=http://www.computerweekly.com/feature/Cloud-backup-options-Pure-cloud-vs-hybrid-cloud-backup|accessdate=3 September 2015|work=computerweekly.com|publisher=TechTarget|date=May 2012}}</ref>

Hybrid cloud backup works by storing data to local disk so that the backup can be captured at high speed, and then either the backup software or a [[Cloud Storage Gateway|D2D2C (Disk to Disk to Cloud) appliance]] encrypts and transmits data to a service provider. Recent backups are retained locally, to speed data recovery operations. There are a number of cloud storage appliances on the market that can be used as a backup target, including appliances from [[CTERA Networks]], [[StorSimple]] and [[TwinStrata]].<ref>Boles, Jeff.

Hybrid cloud backup is also beneficial for enterprise users who have security concerns. When storing data locally before sending it to the cloud, backup users can perform the necessary encryption operations, incl. technologies like:
