My Aperture vault was stored on an AFP mounted shared folder on a Synology NAS.
I use Synology’s Hyperbackup to backup the NAS folder to the Synology C2 cloud storage.
Yesterday I opened the Aperture library in Photos (4.0) and it imported the Library ok changed the name to “Aperture Library.migratedaplibrary” and created a Photos library in the same folder (I have renamed this) “Photos Library 2009-2016.photoslibrary”. When my Synology backup ran overnight It failed saying insufficient destination space.
I read in “Take Control of Photos” that the process of importing an Aperture library actually creates hard-links and does not double the storage space taken up. The backup software running on the NAS is obviously trying to back up both libraries.
So my question is am I safe to just delete the “Aperture Library.migratedaplibrary” assuming I never want to open this in Aperture again?
