For instance when your hard drive dies, your Windows will not boot or is corrupt, your machine is stolen, an upgrades goes horribly wrong, or other major disaster that requires a complete rollback of the entire machine and do a system image recovery. Where disk image backups really shine is in a complete disaster type of situation. Some software such as NovaBACKUP for example, allow you to backup changes since the last full disaster recovery backup. This is a very simple to configure type of backup where you just select an entire drive, partition, or an entire machine, which typically backs up the entire selection you have selected. A disk image backup, can be called a number of different names such as: bare metal backup / recovery (BMR), disaster recovery backup, ghost backup, image level backup, block level backup, system image recovery or a clone of your machine. Paragon Snapshot for Mac OEM package includes a single-license SDK for both OEMs and ISVs who may want to build their backup (or some kind of other) software solutions.An image backup is simply an image or copy of your entire system, including your operating system. The advantage of a snapshot in comparison is, the image-based backup contains changes made at the very moment the snapshot is taken, so all the associated files in the group are in the same state. File-based backups do not guarantee the consistency for a group of files, compared to sector-level snapshot-based image. Users may not be aware of this issue and continue changing particular files that reside within a group of files which require consistency.
The majority of current backup solutions for OS X work at a file level. As a result, a file-level backup archive contains all files at different moments of time, so their states may differ. Retrieval of data, multimedia and system files can be a very risky task. Mac computers become increasingly popular in the content development and many other business segments where data-loss can be a nightmare.
