Where each one falls short

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

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

Datto SIRIS

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