What is BackupClever?
BackupClever is a backup utility for Windows.
It combines the benefits of incremental backups (less space) with the freedom of full backups (all files accessible). After an initial full backup, only modified files will be copied while representing the others by NTFS hard-links to previous backups.
When a backup is done all source files are compared with already existing files in previous backups. If there are changes, a new (time-stamped) backup directory is created and all modified source files are copied to it, unmodified files are integrated as NTFS hard-links to the existing files of previous backups. This allows having a complete copy of all source files and folders in each backup set, while only reserving the space of one initial backup plus the differences between each subsequent backup on the backup media. Unused backup folders (including the first full backup) may be deleted safely at any moment without impacting the integrity of the other backups.
