Does anyone have a solution for syncing large directories/filesystems using just a USB flash drive (and specifically without using a network connection)?
The objective is simply to sync a user directory between two computers. The contents of the user directory could amount to a large quantity of data—say, a quantity larger than could be stored on any single USB drive—but the aggregate size of changes that must be propagated by a single sync could easily fit on a USB drive.
As an example, suppose a user directory is already synchronized between a desktop and a laptop computer. Here's a use case:
- Some changes are made in the user directory on the desktop.
- We mount a USB drive onto the desktop and copy whatever changes need to be applied to the laptop user directory in order to synchronize the desktop and laptop user directories.
- We now mount the USB drive onto the laptop and apply the changes.
- The desktop and laptop user directories are now synchronized.
