In a corner of my front room: a hand-me-down tower computer with FreeNAS storing data in a relatively large ZFS pool, conforming to Apple's Time Machine Network Interface Specification (TMNIS) although in recent months, I rarely use this Time Machine server with any Mac client.
I typically use the NAS as a target for replications (backups) that are
automated by Life Preserver – a feature of PC-BSD and, more recently,
TrueOS Desktop.
All ZFS on the notebook that I currently use, somewhat more capable than the Mobile Time Machine (MTM) that
is was normally available to users of Apple notebooks.
Yesterday evening, after a refresh of Firefox removed much more than was desirable, I used an automated snapshot to regain what was required. Copied from the ZFS snapshot and pasted to my 'fresh' Firefox profile.
This screen shot of yesterday's incident shows
Insight – a feature of Lumina desktop environment, used here with KDE Plasma 4. Note the difference between the real time (19:49) and what's on the
timeline in the window of Insight:
A quick comparison
Time Machine browser is pleasantly three dimensional and plunges the user into outer space, away from nearly everything that's associated with Apple's desktop environment. There's a single window of Finder, with a specialised set of tools in its toolbar.
Insight readily does what's required in harmony with the desktop environment.
Ouch
I
must re-investigate my options for remote/WAN backup.
macOS Sierrouch
Release candidate build 16A319 with a MacBookPro11,2. Time Machine has not automatically used Mobile Time Machine for local snapshots, neither can I find (in the Time Machine pane of System Preferences) a way to enable the feature. I wonder whether it was quietly deprecated … over to
the macOS Sierra area to ask a few questions …
