rsync copies files...period. It's just like cp -r, or scp -r, but smarter.
It doesn't know about 'dependencies'. It's not really a backup too, but can be made into one.

Subject: Re: [Novalug] Upgrading from Fedora 13 to Fedora 17/18
One of the issues not specifically mentioned on several
discussions I've seen is application backup. Windows and
linux have exactly the same problem, and that is the app code
and dependencies and multitudes of libraries and where they are put.
Once you upgrade the specific OS, and lets includes the desktop and
the graphics system, usually gnome or kde , you are not going to get
your old applications back. In windows, you WANT your old apps
to avoid BUYING new ones. In XP, I use Office 2000.
In Linux, you generally want the newer versions...
perhaps not in all cases, There are (few) cases where
the newer app doesn't work as well in the newer OS distro,
but you generally want the newer apps. Result: in linux you don't
backup apps.
User files are another matter.
So the interim Q is: does rsync sync up the apps "as is" ?
Can it flesh out the dependencies or only go by install dates etc?
note: I have not used rsync nor looked at the manual, so I don't expect
a discourse on it's use but perhaps some info on it's scope for a user.
One example, I recently went thru multiple hours adding apps,
not including installing the original OS. Many came from "free"
and "non-free" places. I then had 2 programs to play media.
That went well for a couple of weeks. Totem player, Dragon.
But when I transferred into the PC a data file that I wanted to
"convert" ( what doesn't matter ), I couldn't The related media software
had no simple editing including "save as" or "convert". So, while
perhaps I had loads of enocders, I needed to install, lets say,
mencoder errrrrr..... mplayer.... knoobees need to know this name.
OK, so a "add package" resulted in ....
"You also need to D/L and install 18 other packages.
Do you want to do this? "
Bear in mind, all this is to get equivalent function in the newer
OS that the old one had. No backup of the old applications.
Nor would they work.
Perhaps in 3 more years when everyone has a 100 gig SSD
drive, none of this will matter.... but oooops !!!!
People seem to be buyin 3 Tbyte drives... I HOPE as usb add-ons...
for user data --- and not for the OS...
But OS expansion being what it will be....
Linux was once a 10 mbyte D/L ..
Addendum.
I know about VLC. Very nice. It's now on my Windows XP.
Still can't be installed on CentOS6. Some dependency problem.
yes, I have all the updates. RH issued some "security" release
of some lib that turned out to be a 1.0.x new. The prev was
0.99 or some such. Can I assume that in the install scripts that
version number rollover is not computed correctly when checking
for compat issues between dot versions ? or not.
Can someone confirm this ?? Wait... I'll bet every package maintainer
uses their own version of a version compat script ....

Sigh. NEVER EVER use a CD or DVD to "back up data". They are Too Small and take FOREVER to Burn!
Get a USB Disk and Use That! rsync is The Best tool for almost ANY copy. PERIOD.
