diskBu

diskBu is a command-line utility designed for backing up and restoring disk images. It allows users to create compressed backups of entire partitions or disks, and to restore these backups onto other storage devices. The tool supports various compression algorithms, enabling users to optimize backup size based on their needs. It is primarily used by system administrators and advanced users for data recovery, system migration, and creating portable disk images.

The primary function of diskBu is to facilitate the creation of raw disk images. These images are exact byte-for-byte copies of the source storage, ensuring all data, including boot sectors and partition tables, is preserved. diskBu can also apply compression to these images, significantly reducing the storage space required for backups. Restoration involves writing the image back to a target disk, overwriting its existing contents.

Key features of diskBu include the ability to specify source and destination devices, select compression methods, and perform differential or incremental backups. Error checking is also a component, aiming to ensure the integrity of the backup process. The utility is often employed in scenarios where a full system backup is necessary, such as before major hardware changes or software upgrades. Its command-line interface makes it suitable for scripting and automation of backup tasks.
