So here's the good and the (not so good) news:

1) My backup using a fresh-built 6.29.2 on msm8960 only took about 10-20 seconds! ;)

2) When I looked at the files, none of them but /recovery partition were greater in size than 20-30 bytes.

Log from that session:

__bionic_open_tzdata: couldn't find any tzdata when looking for localtime!
__bionic_open_tzdata: couldn't find any tzdata when looking for GMT!
__bionic_open_tzdata: couldn't find any tzdata when looking for posixrules!

Errata: Other things I tried (assuming it was just my build that was bad):

Rebuilt prior recovery version to test my build env.

Re-synched cm11 and did a clobber, re-fetched your git and did a make

decided to check in here, see if anyone else had a problem.

Finally: I decided that since I needed to go out for most of the day coming up that I'd not try a recovery either. Oh yeah: I used the vanilla command "backup to /sdcard" to get this log of the failed backup.
