If you were on a laptop with limited HD space (and ZFS did not work with file recovery), would you:
A. Use HFS+ for the recovery, or...
B. Use ZFS for the space?

Erm, I am insufficiently educated to make the decision? :confused:

Is your idea that ZFS is less likely to result in data corruption and so you need the backup space less?

Use HFS+ for the recovery and buy an external for space.

:confused: Leopard can use ZFS?

Yes....in the seeds it is an option, but does not function (last I heard...)

Maybe that's what's delaying it. :)

I don't really know anything about ZFS, why does it not work with file recovery?

Well, my only experience with HFS+ recovery is that it's practically impossible, so i'm willing to give ZFS a try :-)

C: Upgrade my hard drive and not worry so much about the filesystem.

I think the OP is referring to the fact the Time Machine works with HFS+ and ZFS currently doesnt. SO in Leopard you could recover with HFS+ but not with ZFS.

Or i could be wrong.

I would probably go for the HFS+, i am a bit of a backup freak.

I'd hold off on all this until Apple finishes Leopard, and fixes the bugs with its ZFS implementation - hopefully, by then, this will be a moot point since Time Machine and ZFS will get along :D

LOL, correct answer ;)

How does ZFS provide "more" space? Or does HFS use space for indexing that ZFS doesn't do?

ZFS is far more sophisticated than HFS+, and thus doesn't need space reserved for the journal file or various other HFS-specific things. This would free up some HD space, but not much (perhaps on the order of 10-100 additional megabytes).

Also, ZFS would implement the Time Machine backup system FAR more efficiently, assuming that Apple gets Time Machine and ZFS to work with one another. This would save space on your backup volume.
