[clue-tech] Re: More questions on backups, auto backups and mounting

[Adrian F. Nagle, IV]

Another question:
My external Seagate drive has /RECYCLER, /_SYNCAPP, /System Volume Information, and /lost+found directories.  Are these directories I can delete, or if they should remain, do they need to be backed up?
