• Can copy files between many types of storage: Hard disks, burn CD/DVDs, USB drives, MP3 players, internet backup services (using WebDAV), FTP & Secure FTP servers and more.
• Has the ability either to synchronize files, or synchronize with "chunks" which are small to medium sized compressed and/or encrypted zip archives. This is a very unique feature of Backup Chunker; you can back up all your files to small to medium sized archives (using the common zip or 7-zip format) that are both compressed and encrypted. On each backup, only the new and modified files are re-compressed, and only the affected chunks changed.
• Can handle many different scenarios, like synchronizing files between many computers and storage devices. For example you can sync your home computer with a USB stick (using compression and encryption), and then your USB stick to your work computer. This way you can keep your computers synchronized and also have a compressed & encrypted backup copy on your key chain!
• Archive format used is the common zip or 7-zip that can be extracted if required with any simple file compression utility.
• Industrial strength encryption (AES-256) that has no back doors.
• Extremely fast synchronization of thousands of files, even to locations on a network or the internet.
• Backup Chunker can help with all day-to-day backup scenarios, for simple or demanding tasks. Our solution is especially good if you have thousand of files that need to be saved for backup purposes or frequently synchronized with other computers and back.
