You should use the -c option of rsync for encrypted volumes, else it will consider every file has changed.

How long does it take to finish the two types of backup? I don't think it will be finished within two days, I have backup my data using "trusted backup" as you name it, and it took 1 day for me after it's done.

I use duplicity for my backups. It produces tar encrypted volumes and has lots of backends, such as sftp, scp, imap.

I produce an daily incremental and weekely full backups. I keep two full backup sets. I use it for both trusted local and off site backups. The advantage is I can simply copy my local backup to a portable usb drive and take it with me, knowing that my sensitive stuff is encrypted and if I lose the drive no one can read it.

Duplicity is available in the Ubuntu repos or from http://www.nongnu.org/duplicity/

a question: I've switched to ecryptfs $HOME, but with a plain fs an rsync would last in 20 minutes, now with encrypted one it lasts about 4 hours!
It is normal? I know there is a performance penalty, but... There is something that can be done to speed up?

Out of curiosity -- for your (encrypted) offsite storage, do you have any way of producing easy-to-interpret results from rsync --delete --dry-run?

It seems to me like that would just show a list of long, opaque encrypted filenames, which isn't particularly easy to screen for accidental changes.
