"Mounting backups as a virtual drive" refers to a feature in backup and recovery software that attaches a backup (e.g., of files, a server, or a virtual machine) so it appears as a regular drive within the operating system. This enables users to browse, open, and restore data directly from the backup without fully restoring the entire backup set first. In many cases, the mounted backup is provided in read-only mode to protect backup integrity.
Attach backup as a drive: Presenting a backup image or backup set as a virtual drive (e.g., with a drive letter or mount path).
File and folder browsing within the backup: Navigating the mounted backup like in the file explorer, including search and filters.
Granular restore: Restoring individual files, folders, or specific versions directly from the mounted backup.
Point-in-time mounting: Mounting a specific restore point to access the exact state of data at a chosen time.
Mount options and access control: Read-only/read-write options, role-based permissions, and access logging.
Application-consistent recovery support: Providing application-aware restore states (e.g., for databases) to ensure consistent data.
Mounting VM backups: Attaching virtual machine backups (e.g., VMDK/VHDX or similar formats) for file extraction or fast recovery.
Instant recovery / instant VM boot: Starting a VM or making workloads available directly from backup storage without full restore.
Validation and integrity checks: Verifying readability and consistency of the backup before or during mounting.
Automatic unmount & cleanup: Time-based unmounting and cleanup of temporary mount artifacts.
An administrator mounts a file server backup as a virtual drive and restores a mistakenly deleted project folder.
A helpdesk team mounts yesterday’s restore point to extract an older version of an Excel file without rolling back the entire system.
After a ransomware suspicion, a backup is mounted read-only to check which files remained unchanged prior to the incident.
A virtual machine backup is mounted to copy specific configuration files instead of restoring the full VM.
For a critical application, "instant recovery" is used: the VM is started directly from the backup to minimize downtime while the full restore continues in the background.
