iPhone backup shootout: iTunes vs. rsync

iTunes' iPhone backup is absolutely horrid. i've just about decided to completely replace it with rsync, so i figured i'd give it one last go. it's been 2 hours since i plugged my phone in and iTunes auto-synced. it's been over a week since my last rsync backup. how do they compare?

time

iTunes backup—crashed after 1.5 hours. resulted in corrupted backup, will not be able to restore from it.

rsync—5 minutes, 32 seconds.

connection

iTunes backup—plug in via dock connector/usb.

rsync—wi-fi.

speed

iTunes backup—USB 2.0 theoretical maximum: 480 Mbits/second. actual speed: approx 2.3 Mbits/sec.

rsync—actual transfer speed: 440 Mbits/sec.

data transferred

iTunes backup— ~16 Gb

rsync— ~155 Mb

data availability

iTunes backup—stored in a single compressed image. not available.

rsync—stored in a standard folder on my data drive. very available.

revision availability

iTunes backup—last backup. available only as a complete reimage, assuming the last backup didn't crash. if last backup crashed (about 66% probability, in my experience), not available at all. ever.

rsync—thanks to the magic of Time Machine, every single sync is backed up. every change. every revision. these backups can be restored piecemeal, as needed.

ease of restoration

iTunes backup—plug in phone. hope iTunes has a valid backup image. curse.

rsync—run the reverse rsync command, go about your merry way. can restore a single app or folder, or the entire iPhone.

triggers

iTunes backup—plug phone into computer, manual sync.

rsync—cron jobs, folder actions, bluetooth proximity, IP address availability, manual sync.

approx wait after plugging phone into computer before i can do anything with my phone other than looking a pretty "syncing" screen

iTunes backup—1.5 hours

rsync—0 seconds

final score

iTunes backup - 0. rsync - 10.

verdict?

wow.

Now I just have to figure out a way to get music/video content onto my iPod without having to wait through the backup portion of the sync...

Or Apple needs to get a clue and have the backup be optional. What do you think our chances are?

the backup is optional. there's a pref flag you can set:

defaults write com.apple.iTunes DeviceBackupsDisabled -bool true

set it back to true if Apple gets their act together and fixes the backup. otherwise, rsync is your friend :)

cron jobs, folder actions, bluetooth proximity, IP address availability, manual sync.

Is there a writeup somewhere of how to do this with the iPhone?

not that i know of. maybe i could whip one up when i get a minute...

ease of installation

iTunes -- no installation necessary; backup is available out-of-the-box.

rsync -- installation voids your warranty.

(Scoring for this item depends on how much you value your warranty.)

this is a very valid point. i happen to value my freedom more than my warranty... i bought an iPhone with the intent of jailbreaking it and using MobileTerminal and friends to replace part of the functionality of my laptop.

i'm not sure that i can speak for everyone though.

Are you using firmware 2.0?, so far I am unable to restore using rsync. Backup goes swell but I am unable to use this backup for a complete restore.

I am using the 2.0 firmware. To restore, I reimaged with a pwnd firmware, installed rsync with Cydia, then rsynced back. I couldn't come up with a quicker way to do it than that...
