Backup to CD/DVD with disk spanning (compression not required). SyncBackPro can also backup to an ISO image file which can be mounted as a virtual drive (using 3rd party software). SyncBackPro also performs automatic disk spanning, i.e. if your files do not fit onto the CD/DVD then it will split the files and continue onto another CD/DVD. SyncBackPro delivers the tried and tested functionality of a program now in version 5 that has received numerous accolades and awards for being the very best backup and synchronization software on the market.
