Cobian Backup was originally released in 2000. The program was later rewritten and released under version 7. The next version (version 8) was released in 2006. Its source code was later released under the Mozilla Public License in late January 2007. However, with version 9 the author of Cobian Backup decided to switch back to a completely closed source model. Older versions will remain Open Source forever, as the release of the program under the Mozilla Public License cannot be revoked.
Development and support by the original author has been discontinued with version 18.104.22.1682 and the source code has since been sold off.
Cobian Backup supports Unicode, FTP, compression (ZIP, SQX, 7z), encryption (including Blowfish, Rijndael, DES, RSA-Rijndael ), incremental and differential backup, for example a differential backup every night (which backs up user files that have changed since the last full backup) and a full backup every seventh night (backing up a full set of user files). Backups can be saved to CD, DVD, USB memory stick, a second hard drive (internal or external), etc. It supports long file names (32,000 characters) for all backup routines.
