So a few things:
- The client will do discover before syncing (this can take some time if you have 26GB of files indeed)
- If your reboot/restart your system/client the process starts all over. This is done since we can’t trust the previous state. If the client did not run you could still have modified the files on disks. This is done against a local db. But for that to be used you first need a completed sync run.
So long story short. Keep your machine on to let the first sync complete.
