I'm using my desktop and a single board cpu (Raspberry Pi 2 - 900 MHz) to sync two very large directories with large files. Often, the files are the same but the filenames are changed. Unison is suggested here for that purpose, which I've used to good effect for smaller directories / files.
However, waiting for the single board to hash the files takes a very long time.
Is it possible to pre-cache the hashes so that I could run it overnight periodically with cron?
# Roots of the synchronization label = Precaches Media Server auto = true root = /media/Files root = /media/Files
However, syncing against itself causing a locking issue
