zfs discuss - Sep 2008 - ?: any effort for snapshot management

I have seen Tim Foster''s auto-snapshot and it looks interesting.

Is there a bug id or effort to deliver snapshot policy and space 
management framework? Not looking for a GUI, although a CLI based UI 
might be helpful. Customer needs something that allows the use of 
snapshots on 100s of systems, and minimizes the administration to handle 
disks filling up.

I imagine a component is a time or condition based auto-delete of older 
snopshot(s).

Thanks
Steffen

Steffen,

Most complete and serious ZFS snapshot management, integrated ZFS
send/recv replication over RSYNC with CLI, integrated AVS, GUI and
management server which provides rich API for C/C++/Perl/Python/Ruby
integrators available here:

http://www.nexenta.com/nexentastor-overview

Its ZFS+ with a lot of reliability fixes. Enterprise quality, production
ready solution.

Demo of of advanced CLI usage is here:

As a side not, I think that dis-integrated general-purpose scripting
which is available on the Internet simply can not provide production
quality and easy of use.

I think I can answer those questions.

Firstly, Tim is working with some of Sun''s desktop guys to put together
a GUI for his stuff.  I don''t know how long it will be, but
I''d guess that you''ll see that as a full part of OpenSolaris
sometime this year.

Regarding snapshot management, I believe there are two types of filesystem quota
in ZFS now.  The original quotas include snapshot space, and you can also create
a quota that applies to the main filesystem only.  I don''t know the
details of which settings they are I''m afraid, I just remember reading
that the two types of quota had been implemented.

I would have thought those quotas, plus the auto-delete ability of
Tim''s snapshot tools should fulfil most needs.
