rsync backup of /home/.ecryptfs causes errors

[Daniel Convissor]

Hi Folks:

I asked the following question at launchpad, but haven't received an 
answer.  Perhaps the folks here can help, please.

I am trying to use rsync to backup the /home/.ecryptfs in Ubuntu 
9.10/Karmic, but doing so produces error messages for users who are 
currently logged in. Considering this issue, how is one supposed to 
cleanly backup .ecryptfs?

Here is the command I ran:

rsync -aH --delete /home/.ecryptfs /bk/rsync-home

And here is the output:

rsync: read errors mapping 
"/home/.ecryptfs/ent/.Private/ECRYPTFS_FNEK_ENCRYPTED.FWaWKXqVAx32y
...snipped for brevity on the mailing list... JjCVaJA8D.E-":

rsync error: some files/attrs were not transferred (see previous errors) 
(code 23) at main.c(1057)

Thanks,

I'll update the launchpad page if a good answer comes out of this.
