Backup or Update.zip? - Android Software/Hacking General [Developers Only]

Just a general question. I'm new to flashing ROMS and I was curious about is there any advantage to creating an Update.zip file over using my recovery program to backup my current ROM? thanks

Mycontacts backup installer?

Long story short....I upgraded to a new rom that doesn't include mycontacts backup...which is what I used to backup my numbers. Does anyone have a standalone install file of this app by chance?

Two recoveries?

After downloading the newest ROM manager from the market, it now looks like I have two recoveries installed. If I boot into recovery from ROM Manager, I get the new blue one (with int SD support). But if I boot from the power menu, I get the old one. Something tells me I screwed something up, and I'm not touching anything until somebody tells me how this is even possible. WTF did I do?

No problem there. ROM manager is only updated false flash rom. Old one is the nvflashed real one.

Ah. So is it safe to flash from either one? Having access to the internal SD would be a lot more convenient.
Also, is there a thread somewhere pertaining to this situation?

There is an even better scenario...download the utility by tgagunmann in the development section, and flash the latest cwm, which allows both internal and external from boot recovery.

Rom manager I think only reboots you to recovery and does it, so its kinda the same of backing up the phone. Titanium backs up all the apps and its what people use to restore apps between ROMs.

Go to CWM and restore your backup.
Agree with above, if created with CWM then use CWM once again to restore.
Cant it be made a single flashable zip?

You have to boot into recovery and use that to restore. It automatically extracts all files and does everything for you.
I think it has to be in /sdcard/clockwordmod/backup/
I think...
