This is Colorado Backup II version 8 which is currently available free on HP's website. Driverguide has a link to it but HP are notorious for 'losing' stuff so here is the file exactly as downloaded from HP.
It works perfectly with my surestore 5000 on 95 and 98SE. It can handle backups made with earlier versions of CBII and MS backup. It also creates tapes which can be read by MS backup and Seagate Direct Tape Access which can be useful. (CB II version 7 tapes are not readable by these other programs.) It integrates perfectly with the Windows task scheduler and maintains a catalogue of all backups.
