The short version

  • Only Trilio has a free tier, so it costs nothing to try first.
  • Each has a real cost: Comet Backup per-endpoint costs ($2/month per endpoint) can add up for large deployments with many protected machines; Trilio coverage is deliberately narrow, so a mixed estate with VMware and physical servers needs a second backup product and two sets of restore procedures.
  • They diverge on capability: Comet Backup covers White-label branding, Trilio covers OpenStack backup.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

Comet Backup

  • Per-endpoint costs ($2/month per endpoint) can add up for large deployments with many protected machines
  • Advanced and Enterprise tiers with additional management capabilities are significantly more expensive than base tiers
  • Platform-specific features (SQL, MySQL, MongoDB, Microsoft 365) have separate per-unit pricing

Trilio

  • Coverage is deliberately narrow, so a mixed estate with VMware and physical servers needs a second backup product and two sets of restore procedures.
  • Trilio is a small vendor next to the backup incumbents, and buyers with ten year retention obligations should assess the risk of the company being acquired or wound down.
  • Enterprise pricing is per node or per virtual machine and is not published, which makes it hard to compare against per-terabyte competitors without going through sales.
  • The free basic edition stops at ten nodes with community support only, so the step from evaluation to production is a full commercial negotiation rather than a tier upgrade.
  • Restore performance depends on the object storage or NFS target you supply, and egress charges from a cloud object store during a large recovery sit outside the vendor quote entirely.

Answered from the vendors’ own pages

Comet Backup: How much does Comet Backup cost?

Self-hosted plans start at $19/month (Starter) and go up to $99/month (Advanced), with cloud-hosted plans starting at $49/month (Professional). All plans charge $2 per endpoint per month for additional protected machines beyond the base license count.

Source
Trilio: Is the free edition production usable?

It is functionally complete up to ten nodes with community support only. Use it to evaluate, but understand that production incidents have no vendor behind them at that tier.

Comet Backup: What is the price difference between self-hosted and cloud-hosted deployments?

Cloud-hosted plans start at $49/month (Professional) versus self-hosted which starts at $19/month (Starter). The main advantage of cloud-hosted is Comet manages the console infrastructure, though both models charge the same per-endpoint fees.

Source
Trilio: Does it support OpenShift Virtualization?

Yes, which is the main reason it appears on shortlists for organisations moving virtual machines off VMware.

Comet Backup: Does Comet Backup charge for additional protected machines?

Yes, all plans charge $2 per endpoint per month beyond the licensed endpoints. For example, the Growth plan includes 2 self-hosted licenses, but each additional protected machine costs $2/month.

Source
Trilio: Where are backups stored?

On NFS or S3-compatible object storage you provide, in an open format rather than a proprietary vendor container.
