Mac OS X does not natively support iSCSI, it has no native iSCSI initiator (client). Just disconnect it from your NAS and hook it up to your Mac.īecause hard drives attached through iSCSI are seen as normal storage, you can also encrypt them with the Apple build-int whole-drive (or whole-partition) encryption. In case of an emergency - when your boot drive dies - you can boot from this external hard drive. I would just hook up an external USB drive to my NAS and export it through iSCSI. This trick allows you to create bootable Super Duper clones of your boot drive through the network. iSCSI is totally transparent from the perspective of the operating system. Your computer does not see the difference between an external USB hard drive and a hard drive exported through your NAS to your computer. This is very cool, because you can export entire hard drives through the network to your computer. Since iSCSI uses your Gigabit network as a transport, you can achieve transfer speeds of around ~110 MB/s easily, which should suit most needs*. Most NAS devices support iSCSI and allow you to carve out some local NAS storage and present it to your computer through the network as if it was just local storage. It's basically a storage protocol tunneled through your home LAN network instead of a USB / Firewire or Thunderbolt cable. Now there is a cool technology called iSCSI. Those NAS devices pretend to be Time Capsules, but there's always the risk that Apple breaks compatibility with a future update.įrom my experience, Time Machine backups are only 100% reliable with local attached storage - like external hard drives. The main problem being the reliability of network-based Time Machine backups. I'd like to move away all my storage from my living room (or home office) and put it in another room or even closet.Ī NAS may help with that but a NAS does not solve all problems. External hard drives make noise and create clutter. In the past, as a Mac user, I've used separate external drives for Time Machine backups and Super Duper clones but I'm not happy with that.
