Hm... v2.6.24 is four years old... Maybe you mean v2.6.34,
and May 2010?

Hm... I have these settings in the FileSet definition:
Include {
Options {
signature = MD5
xattrsupport = yes
aclsupport = yes
}
File = /usr/bin
}
When restoring, the file attributes were lost anyway.
Is there any other place I need to give extra options? When
restoring?

Guess why I've been using bacula for so long...
And btw: thanks :-)

I'm just a user of bacula, no developer of it, so I don't care much
about the implementation or the interface. As long as the
functionality is present and working I'm fine with it.

In the linked PDF file I cannot find a reference to cpio or rsync.
But rsync does indeed work as needed when using -X. Sorry, I missed that.
The cpio in Fedora 16 does not appear to support this.

Done that, but I could not see any.
This is with bacula as distributed with Fedora 16, most recent
updates installed:
bacula-client-5.0.3-13.fc16.x86_64
bacula-common-5.0.3-13.fc16.x86_64
bacula-console-5.0.3-13.fc16.x86_64
bacula-console-bat-5.0.3-13.fc16.x86_64
bacula-director-common-5.0.3-13.fc16.x86_64
bacula-director-mysql-5.0.3-13.fc16.x86_64

bacula-storage-common-5.0.3-13.fc16.x86_64

Thanks in advance.
