can be used, I believe, in the same way to shied you from the

Thanks Scott! Being a fairly recent Mac user (moving from Gentoo),
this looks like it will work out just perfectly. Consider anacron to
be
off this machine soon.
I did not mean to bash anacron, I am sure it is great software. For
your needs, launchd should give you more granular control.
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.
Yeah, passwordless login is working just fine. That wasn't the
issue. It
was
just getting the script scheduled to run under user credentials.
Launchd supports setting users and groups, also supports logging to a
specific file, as well as setting a working directory so you do not
have to fight with really long paths and paths with spaces in them
within the file.
One think about Lingon, which I reco'd to you, is it will in fact
escape the spaces in a file path, which my experience, and those on
the launchd mailing list, state to not do.
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.
I don't have my rsync command line in front of me right now (at work),
but I've
pulled and consolidated a bunch of rsync scripts for Mac users from
the
web. Do
you have any special flags that you recommend, and I'll compare them
with
what I have tonight.
Yes, I think the single most important flag is:
-E, --extended-attributes copy extended attributes,
resource forks
This is very easy to test. I am not sure what software you use, so I
will list a few. Interarchy bookmarks, those will break if you lose
the extended attributes, Quark files, not that I use them, but I have
broken them. Ahh, what the heck, a .webloc is a forked file. Drag a
url out of safari onto your desktop, it will make a .webloc file. Run
your rsync, and see if that .webloc can open the url again, if it can,
chances are pretty good you are doing the right thing.
Grab a few random files and do:
md5 /path to original
md5 /path to copy
If those md5's match up, you also know you are doing pretty good.
Hope that was of some help, good luck with your scripts.
