I've got a TrueCrypt volume that I would like to rsync changes to over

accomplish this, but it looks like my local user does not have write
capability to the anacron spool directory. Digging online shows that
it
is possible with some versions on anacron to run it under users
credentials and to use the command line option -S to specify a
different
spool, ideally in $HOME. But this option isn't available in macports
anacron. Does anyone have any ideas here?
Perhaps you may want to ditch anacron, and look into launchd? Lingon
can be used, I believe, in the same way to shied you from the
intricacies of OS X scheduling.
If you are able to run interactively your rsync script, which I assume
asks you for a password to login, then anacron, or launchd are both
going to need keys on the server no matter what.
Somewhere, you have to have the keys to do a passwordless login. If
your machine is compromised, you can always revoke the keys quickly.
Reading a little about anacron, I can not see there being anything
launchd can not do, and much more.
Curious also, make sure you use rsync correctly, if you are syncing
mac files, there are special flags you need to add in order to not
nuke your Mac OS X resource/data forks, thereby breaking your files
and having an incomplete backup.
Hope this is a little helpful, not entirely the answer you were after,
but something I think in the end you will be more happy with.
