Differential Backups Save Time and Storage Space

BackupChain generates differential backups to external USB, eSATA, and FireWire drives, or even to network shares or FTP locations.

The built-in delta compression feature, also known as file version differencing, scans files, finds the changes that occurred, and extracts them for backup.

Unlike incremental backup, this feature allows you to restore large files with long file version histories in just one step, whereas incremental backups need to be restored step-by-step going through each file version. Differential backups are ideal for virtual machine backup or and database backups because they detect the relatively small file change that occurs from backup cycle to backup cycle.
