Does IBackup for Windows support two-way sync?
IBackup for Windows supports two-way sync in a limited sense. An interactive or scheduled backup can be considered as a one-way sync process. An interactive or scheduled restore can be considered as a reverse sync process. The best way to implement this would be to setup one-way sync first. Once one way sync completes successfully, setup restore for reverse sync. It will be tricky to setup both at the same time since some variables including estimated time to complete one-way sync and the selection of files/folders for restore may not be known in advance. If all the necessary variables are known, you can automate this entire process.
