Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

AvePoint Cloud Backup

  • No pricing is published, so the per-user cost has to be established through sales, and it varies with data volume rather than being a flat seat rate.
  • Whether AvePoint or your organisation holds the storage account and encryption keys is a configuration decision that is expensive to reverse later, and buyers often accept the vendor-managed default without considering it.
  • Per-user pricing means organisations with many low-activity accounts, such as education institutions with dormant student mailboxes, pay for seats with almost no data.
  • Restore of very large SharePoint sites and Teams structures is slow and API-throttled by Microsoft rather than by the product, so recovery time objectives set on paper often cannot be met in practice.
  • The breadth of the AvePoint portfolio means sales conversations quickly widen into governance and migration products, and buyers who wanted only backup should expect to defend that scope.

Datto SIRIS

  • Requires on-premises appliance, not purely cloud-native
  • Initial setup and hardware costs can be substantial for smaller MSPs
