This Joel dude updates Titanium Backup like in every 3 days. He should work for HTC.

Now with the 2.1 update for Hero is out, this Titanium Backup becomes more invaluable with all the flashing and re-flashing ROM activities. Worth every sen I donated. The Batch mode is too awesome. I'm nicknaming this as 'Norton Ghost for Android'.

Looking forward to use it on FroYo.

Yes, it's always available.

The latest update includes a feature to specify the folder where you want your backups to be stored. So you can have multiple folders. I find this useful as I can specify a folder just for user apps and another for system+user apps. If I'm flashing ROMs from the same Android version (e.g an Eclair ROM to another Eclair ROM), I'll use the system+user apps to restore. If I'm upgrading or downgrading ROMs, I'll just restore the user apps (and deal with system related restore some other way). I learned the hard way that restoring system stuff when doing a downgrade/upgrade will just screw things up.

It's up to the forum administrators to do that. And it has been discussed in the Helpdesk forum:-
