So I am currently backing up to a 1TB LaCie Thunderbolt drive and a 1TB Time Capsule. I'm wondering why the Backups.backupdb folder is contained within a sparsebundle disk image on my Time Capsule, but not on my LaCie drive. On the LaCie drive, the backup folder just sits on the drive unencrypted. Any idea why? ----- Also as a side note, why does the Thunderbolt drive claim to get up to 10GB/second and it never comes anywhere remotely close to that? It's fast, but more like 1GB every 10 seconds when copying from my rMBP's SSD to the HDD of the Thunderbolt drive.
