Links of interest for 6 Apr 2009 - 3 May 2009:
- New Time Slider features coming up in OpenSolaris 2009.06 - Some useful and impressive changes are coming to TimeSlider. Time Slider is definitely starting to eclipse OS X’s Time Machine in over-all functionality, and in my opinion, usefulness.
- ZFS Encrypted Backup to S3 - Now you can backup your ZFS filesystems directly to Amazon S3 or the Sun Cloud Storage. No GUI yet, but give it time and I reckon TimeSlider will have this functionality working perfectly.
- OpenSolaris Live USB Creator (Windows/.NET) (PID0.ORG DevZone) - Finally, a Live USB creator for our friends on Windows.
- The Pirate Bay verdict: guilty, with jail time - Round 1: PB 0 - Courts 1. It’ll be interesting to see how this evolves over time. It’ll also be interesting to see how the BitTorrent protocol will change or if a new more de-centralised protocol will emerge from this.
- Solutions for tracing UNIX applications - Quite a good and lengthy article on tracing applications on UNIX. I think a bit more detail and emphasis could have been put in DTrace, but given this is an IBM article and AIX/Linux don’t have DTrace, it’s understandable why they haven’t.

Why do you compare time slider to Mac OS X’s time machine, when they are two different products?
Time slider is a nice front end for the zfs on disk snapshot facility, whereas time machine is a _backup_ facility (also with a nice front end).
On disk snapshotting != backup.
This backup feature is the main selling point. The rest is just nice wrapping. I sorely miss this backup functionality from the time slider + zfs snapshots feature pack.
I agree, they are indeed different products/concepts, however most people I’ve spoken to use them the same way: as a snapshot solution. This is why I compare them. A lot of people view Time Machine’s requirement for an external disk it’s biggest limiting factor from both a convenience and usage perspective (I suspect because they’re more interested in the snapshot-like functionality than the total backup functionality).
That said, it’s external disk requirement is also one of it’s strong points from a backup perspective.
Thankfully, TimeMachine soon won’t even compare with TimeSlider as removable media based off disk backups and network and cloud based (second link above) backups are in the pipeline.
I forgot to mention, you can get your ZFS snapshots backed up automatically to an external device by setting the “zfs/backup-save-cmd” property for the “zfs/auto-snapshot:[interval]” of your choice. Point this at a custom script in which you then perform the necessary backup functionality (zfs send/receive or clone or similar).
Whilst this doesn’t have the nice GUI yet, it will give you backups AND snapshots
[Note to self: I really should write a proper post about using this command for backing up snapshots]
