Differential backup and incremental backup utility
Backup Software / Differential Backup
Daily backups often cost a lot. The technology of differential backup employed in Handy Backup greatly reduces time and storage space required for backups by saving only changes, on byte level.
Handy Backup saves your money by saving only the least modifications of your documents, e-mails, disk images or databases. Download Handy Backup and try the power of differential backups!
Version 7.7.9, built on 22 April, 2016
Differential backup is a process of backing up only those files that were created or changed since the last full backup.
For example, if you do a full backup on Sunday and then perform daily differential backups, then Friday’s differential will contain all data that appeared or changed for the whole work week.
The difference between differential and incremental backup is that the amount of data being backed up is calculated from full backup, rather than from previous backup.
I.e. if you repeat two incremental backups without changing any files, the second backup will contain nothing, while two consequent differential backups will be identical.
Handy Backup supports both differential and incremental backup technologies, as well as mixed full and differential backup.
Another advantage of making differential backups is quick data restoration in case of a disaster.
Unlike incremental backups which need to go through the entire chain from the last to the first backup, restoration of differential backups is done in two steps, using the most recent full and the most recent differential backup.
This backup technique creates a chain of backups, starting with a full backup and then containing some differential backups. When a chain reaches an end, deliberately set by a time or by a quantity of diff backups, the process repeats again, starting with a new full backup.
