I’m a big fan of “sparse bundle” disk images in Mac OS X. They allow me to create encrypted repositories for valuable data that can efficiently be rsync-ed between disks and don’t waste a lot of space. So I thought I’d write up a bit on what they are and how they can be used.
Microsoft already gave the world FAT and NTFS, and both have become common in the non-Windows world thanks to flash drives, SD cards, and portable disks. But the folks from Redmond are now introducing a new filesystem, exFAT. Do we really need a new filesystem?
