But I think you just need to stretch your imagination a little bit to get to a real backup. The hardest problem with OS X backup is preservation of resources forks and permissions. Both of them are very foreign to traditional Mac users, I suspect, and the nice thing about that page is that it explains these points.
Thanks for pointing it out. That's true. That was not a genuine backup. Sorry about inaccuracy.
I'd hate to see someone think that they've protected there system with a backup and discover that they have lost everything because their hard drive crashed.
So think of it as a step to make reinstallation easier.
So, let me update the tips by adding some more information to get REAL backups.
1) You need external media (like CD-ROM, HD-drive, etc) that is
PHYSICALLY separated from you Mac. Zip disk doesn't work
anymore due to the huge size of backup.
2a) Use Carbon Copy Cloner to copy your stuff in your home directory
(and anything else you want to back up, e.g., /Library) on external media
which IS RELIABLE (this point is VERY important.)
Or alternatively,
2b) hfstar -zpcvf <target file name>.tar.gz <source directory name>
to get a gzipped vesion of backup file of your stuff.
Either way, you're done.
Notes on method (2b):
i) traditional tar (or gnutar, gtar) doesn't preserve resource folk
and DOESN'T WORK for Mac stuff (No problem with pure UNIX stuff
like fink, of course). You definitely need hfstar.
You can get hfstar, for example, at:
http://www.macupdate.com/info.php/id/9405
ii) Both <target file name> and <source directory name> specify
the locations of files/directories in UNIX fashion.
iii) I think -p option is required to preserve permissions, right?
iv) If you want to create a fast backup, remove -z option, and .tar extension
from the target archive
Addendum:
You can use hfspax instead of hfstar and CCC, but I've never tried it and am unable to give tips here.
In my case, I haven an external SCSI hard drive and store .tar.gz files there.
Good luck on your backups.
Cheers,
Kow
