NEW Cloud Immutability

  • Immutable backups in the cloud (WORM)
  • The best offsite backup protection from accidental and malicious corruption
  • Backups are locked for the user-specified retention period and then removed
  • BackupAssist manages the cloud object retention period, so no additional cloud storage cost will be incurred by enabling immutability.
  • Seamless discovery and restore from backups, even when the cloud bucket/container data appears to have been corrupted
  • Supports:
    • Object Lock on AWS S3 and S3-compatible providers
    • Immutable Storage on Azure

NEW All New user experience

  • Intuitive first-time user experience
  • Streamlined operation for existing users

NEW VM Instant Boot UI

  • Quickly get your backed-up system up and running as a Hyper-V guest, using this new UI to create and manage the boot files that are needed.
  • The virtual disks created by the VM Instant Boot UI application can be immediately attached to a new Hyper-V guest and started. This process with will not affect the underlying backup, keeping its integrity intact.
  • Works with both local system / volume backups as well as downloaded system backups from a cloud storage.

Improved Cloud stability and performance

  • Automatic request rate management enabled by default for new cloud jobs
