Even though both methods are technically creating backups, there are vast differences in the what, why and how.įirstly we need to clarify the disparities between freeware imaging programs and commercial imaging programs. However, over the years the backups created by imaging software have become known in common parlance as images rather than backups, and the term ‘backup’ has become synonymous with file-based backup software. The former is creating image-based backups and the latter, file-based backups. Strictly speaking, both types of software – imaging software and backup software – create backups. Disaster: when the computer will not boot or is non-operational.In the context of this article the terms ‘drive’ and ‘partition’ are interchangeable.Restoration involves the last full backup/image plus the last differential only. Differential: Always includes all files which have changed since the last full backup/image….Restoration involves the last full backup/image plus all incrementals. Subsequently includes only those files which have have changed since the last incremental backup/image. Incremental: Initially includes only those files which have changed since the last full backup/image.Obviously, there are a lot more people out there who are not familiar with the differences between backup software and imaging software than I originally gave credence to.Īnyway, I do apologize for not acknowledging the fact that the distinction can be confusing for many, I should have properly explained… I’m about to rectify that omission right now.
Last week I published a review of the excellent BitReplica backup software from Auslogics… Auslogics BitReplica: The backup software everyone should have? I was quite surprised by the number of responses to that article complaining that BitReplica does not create images or provide for disaster recovery via bootable media.
