The short version

  • Each has a real cost: Caddy smaller ecosystem than Nginx, so third-party guides and modules are fewer; Clonezilla the destination partition must be equal to or larger than the source partition
  • They diverge on capability: Caddy covers Automatic HTTPS, Clonezilla covers Disk/partition imaging.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

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

Caddy

  • Smaller ecosystem than Nginx, so third-party guides and modules are fewer
  • Adding plugins means rebuilding the binary rather than loading a module
  • Under very high throughput Nginx generally still benchmarks ahead
  • Automatic certificate issuance needs outbound internet access, which complicates air-gapped deployments

Clonezilla

  • The destination partition must be equal to or larger than the source partition
  • Differential and incremental backup is not implemented
  • Online imaging and cloning is not implemented; the partition being imaged or cloned has to be unmounted first
  • The image format cannot be explored or mounted, so a single file cannot be recovered from an image
  • Recovery media spanning multiple CDs or DVDs is not implemented; the recovery ISO must fit on one disc
  • Clonezilla SE requires a DRBL server to be prepared in advance and the target machine to boot from the network
  • Runs only on x86 or x86-64 processors and needs at least 196 MB of RAM
