New laptop: need advice on choice of file system types

[Tom Browder <tom.browder@gmail.com>]

I have used ext4 for many years while I have been watching zfs and
btrfs being developed. I am now considering using one or both on at
least one partion during my upcoming new Debian installation.

Can anyone recommend either one for a normal (non-developer,
non-hobbyiest) user who does backups and values his data and wants
reasonable reliability?

Thanks,

-Tom
