Finally, we wind down with Toucan, a lightweight portable program that can perform file backup and syncing operations, incremental and differential backups, as well as zip and 7-zip compression, encryption, and restore. Rules and filters allow you to fine-tune what goes in and what stays out of the backup, and powerful scripting options allow advanced users to create custom scripts for added functionality. Other programs do image cloning, but for portable file syncing and backing up, this would work great. Install Toucan on a portable drive and take it along with you to backup and sync whenever and wherever necessary.
There's a wealth of free backup options out there, each with their own specialty, and our list is by no means comprehensive. Do you have any other programs to share, or thoughts about the programs on the list? Please feel free to share your thoughts in the comments section below.
