New Time Slider features coming up in OpenSolaris 2009.06

We've made a number of enhancements for Time Slide in OpenSolaris 2009.06.
Under the hood nautilus visualization is now fully multithreaded. This means that you can now browse directories with more than 4000 snapshots without noticeable slowdown (That's more than 3000 years of snapshots if you use the default timeslider snapshot schedule !).

On the visualization side, the interface has been polished and we've added the possibility to manually snapshot a directory (either by right-clicking on a directory and selecting the "snapshot now" menu item or in time slider mode by clicking on the camera icon).

You can also delete snapshots manually while browsing through time by clicking on the delete button.

or by using the delete dialog in the time slider setup dialog (System -> Administration -> time slider setup)

We also added another way to browse a given file history. You can access it by right-clicking on a file and then select the "explore versions" item. If no other versions are available then this item is disabled.

You can then browse the different versions of the selected file.

If you're exploring the history of a text file (be it code and plain text). You can compare visually the difference between the two versions. You just need to select a older version and then click the compare button. If you have meld installed (available from the IPS repo), meld will display the two versions of the file side by side.

Comments:

Nifty, although the real thing OSOL would need imo are fast ips repos. pkg.opensolaris.org is just unusable and I think this really keeps a lot of people away from OpenSolaris.

Hi Erwann - this is looking great! A really powerful feature which looks
like it'll be even more useful than before :-)

One thing I'd love to see is the availability of this timeline on ZFS
FSen exposed over NFS: giving all this power to my desktop users will
only make them more likely to store their important data on their
local machines, instead of the nicely RAIDed, properly backed up,
temperature-controlled fileserver I provide to them!

I read your justification on a previous post for hooking into the
zfs-centric code (snapshot metadata discovery, I believe), but I
thought I'd just post here to let you know that there's still interest
in seeing it client-side, even if that does constrain (for example) my
snapshot naming policy. Being able to let my Linux desktop users have
this functionality would be a real step towards justifying additional
spend on - say - 7000 series appliances ... hint ;-)

@Jul pkg.opensolaris.org is usable and fast. You may consider checking your uplink.
And yes, this timeslider feature is marvelous! As ZFS as a whole is ;-)
Wouldn't go back to something else.
