Hi,
Thanks to everyone who helped write rdiff-backup, the stored-metadata
concept is exactly the approach I've been looking for to back up my OS
X system.
To begin, I'd like to weigh in on the chars-to-quote issue. I think by
default it's best to quote caps on HFS, for greatest flexibility.
However, it's important to many that file-names be readable, so I think
the override-chars-to-quote flag should become official for the sake of
those users who are sure they won't be using their repository with a
case-sensitive
Second, backing up to a sub-directory of the source directory seems to
work only with relative paths (this may be a problem on other OS's
too...). Strangely enough this works fine:
$ cd $HOME; rdiff-backup --exclude=$HOME/rdiff-$USER $HOME
rdiff-$USER
But this yields an error:
$ rdiff-backup -v5 --exclude=$HOME/rdiff-$USER $HOME
$HOME/rdiff-$USER

Finally, there seems to be a bad interplay between hard links and
resource forks. With ~/Hacking/bin/bitkeeper/delta as a hard link to
~/Hacking/bin/bitkeeper/admin, I see this error:
$ rdiff-backup -v7 /Users/vasi/Hacking/bin/bitkeeper test

It seems that rdiff-backup is trying to write a resource fork to a
hard-link of a read-only file, which of course fails. In
PatchITRB.patch_to_temp(), why does it do a copy_attribs() even after
creating a hard link? Isn't that unnecessary?
Thanks again,
Dave Vasilevsky
