Not yet. We are thinking about it for 0.20, but we really need a
convincing use case. The biggest problems are that on clients with no
special software installed, we cannot either enable the special Windows
backup privilege, which allows us access to all files, or enable Volume
Shadow Services which allow us to back up locked files and to back up
files without locking them. These are serious problems.
We were thinking that the easiest solution would be simply to require that
Box Backup is installed on every client. If this is a really big problem
for you and other users, then clearly we will have to reconsider, but it
would be really useful to know exactly why you don't want to run a client
on every machine, and what is stopping you from doing so?
If you were willing to install some kind of agent on every machine, but
not to install a full Box Backup client, then we could also avoid these
problems, but it means quite a bit of extra development work to create
that agent, so we would need to justify that work. Also, the agent itself
is an additional security risk.
On the other hand, if you want to back up Samba shares and you're willing
to live with the above limitations, of not being able to back up files
that your Box Backup user doesn't have access to, or which are locked,
then we can simply fix support for backing up network shares in the
client, which shouldn't be too hard.
So please can you tell us a bit more about your situation?

I don't think we can do that in general, but we could add a restore mode
that doesn't attempt to restore permissions.

I started working on this but some developers were dead against it, saying
that restoring ACLs was not useful and not possible in general, especially
if restoring to a different system/domain than we backed up from. I have
some half-finished code in need to completion, testing and merging, which
I could pick up if ACL support turns out to be really important.
So can I ask, for this question as well, exactly why you want to back up
and restore ACLs and under what conditions?
