Hey guys, Just wondering if anyone has any insight on why this happens. Anytime I backup up my MBA after a day or two of no backups, the size is always between 5-6gb even if I didn't turn on the laptop in those days. Conversely, the desktop backup sizes are always between 4-500mb, even if I don't turn it on for a week. Both systems are backing up 128gb SSD's with pretty much the same software on both so I don't understand what's going on. Sometimes all I do is turn it on and surf the internet or reply to emails and the backup is over 5gb on the laptop. If I do the same activity on the desktop, it's much smaller. Any ideas?
