The short version

  • Each has a real cost: Crossplane requires Kubernetes expertise and infrastructure; UrBackup backups are stored on the server without encryption at rest by default, so the backup server holds a readable copy of every machine it protects and becomes the highest value target on the network.
  • They diverge on capability: Crossplane covers Kubernetes extension, UrBackup covers Windows image backups.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

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

Crossplane

  • Requires Kubernetes expertise and infrastructure
  • Steep learning curve for teams new to Kubernetes patterns
  • Provider ecosystem smaller than Terraform

UrBackup

  • Backups are stored on the server without encryption at rest by default, so the backup server holds a readable copy of every machine it protects and becomes the highest value target on the network.
  • Deduplication relies on filesystem features such as hard links, btrfs or ZFS, so a server built on the wrong filesystem silently consumes far more space and the fix is a rebuild rather than a setting.
  • There is no native object storage target, so offsite copies mean replicating the server storage with another tool rather than backing up to a bucket directly.
  • Restoring a full Windows image requires booting a restore environment, which is a manual, on site procedure that needs to be rehearsed before the day it is needed.
  • A single server holds everything and there is no built in clustering, so its own failure removes every recovery point at once unless you have separately solved replication.

Answered from the vendors’ own pages

Crossplane: Is Crossplane free?

Yes, Crossplane is open source and free to use. It requires a Kubernetes cluster but has no licensing costs.

Source
UrBackup: Does it back up Linux servers as well?

File backups yes, image backups no. The image path is Windows only through volume shadow copy.

Crossplane: What is Crossplane used for?

Crossplane is used to build control planes and platforms for infrastructure management, enabling platform teams to expose safe APIs to other teams.

Source
UrBackup: Is the data encrypted?

Transport can be encrypted, and there is optional client side file encryption, but the default server storage is not encrypted at rest. Use full disk encryption on the server.

UrBackup: Can I back up to Amazon S3?

Not directly. The server writes to local or mounted storage, so cloud copies are made by replicating that storage separately.

UrBackup: How many clients can one server handle?

Dozens is routine on decent hardware. The limit is usually storage input and output during overlapping backup windows rather than client count.
