duplicity question

First off, a big, belated thanks to Seth for the duplicity recommendation a while back for backups. It's worked very well on the two Fedora boxes I have!

Now, the question:

During lunch today, I'm planning on celebrating Fedora 11 release day by...installing Fedora 11! On my laptop. And I'd like to take advantage of everything ext4 has to offer such as encryption and some speed improvements. So, I'd like to completely do away with my /home partition (or the stuff in it) and start over from scratch. I've used duplicity to back up /home and actually did a tar cvzf on /home/mbjohn last night to be on the safe side, but my tgz file ended up being about 20G larger than my home directory, which, um, has me worried. Ultimately, I'd like to know that if I need to, I can restore needed files from my encrypted duplicity backups. In short, is there a file in my home directory now that I need in place after the installation so that I can install files from my duplicity backups? I did some looking and couldn't find exactly what I needed.

Thanks.

Brian

Afraid I can't help with duplicity, but a question about the grossly
over-sized tar backup: Is that 20G larger than will fit on the
partition, or 20G larger than the data? I only ask because just last
week I goofed on my backup script and caused it to tar up the
directory containing the destination tar file. Needless to say, it
didn't like that very much and the infinite loop filled up the entire
drive pretty quick. So, I just wanted to throw that out there in case
you made the same mistake as me.

Also, while I can't speak for the other members of the list, I for one
would be interested in hearing how the migration to F11 goes: I'm
probably going to switch my laptop over Sunday, after I get back from
SouthEast LinuxFest. Good luck with the install!

You need your gpg keys. That should be it.

when in doubt, of course, test it.

Thanks Seth, that's exactly what I ended up doing...after doing some more digging and seeing that duplicity only relies on gpg, I figured it would save my gpg keys (which I was going to do anyway) and do a test. And it all worked!

I'm now running F11 with my home dir firmly back in place!

Now, to get rid of a 60G tgz file :)
