What are best practices for cloud repatriation with backups?

“Organizations are occasionally leaving cloud-based backup services to resume an on-premises workflow.
Reasons for cloud repatriation might include:
- financial (reduction in budget funds);
- operational (management decision to centralize all IT functions);
- security (breach occurring at the cloud provider); or
- strategic (merger or acquisition by another company that does not use cloud-based services).”
