System Snapshot and Rollback Capabilities

KrunchTime · 2016-06-01 05:18:38

I can't remember where I read it, but I recently read about functionality in Fedora that takes a snapshot of your system prior to installing a package(s) to allow you to rollback if there are issues. Sounds complicated and definitely not something that could be expected in the next release, but I thought I'd suggest it for possible inclusion in the future.

Can be done even in bunsenlabs now if you use btrfs as filesystem or Logical Volume snapshotting.

I often use 'fsarchiver', which also has Live backup/Snapshotting

I'm moving this thread to System Admin and stickying it. Good stuff, gents.

KrunchTime · 2016-06-26 21:51:49

Good stuff indeed. Thank you HoaS and damo. wink

@xaos52: I've read of instances where btrfs has borked hard drives. From research I've done in the past, LVM is geared more for server environments.

Hey Folks!

I` m a bit sorry to bring this old thread up again but just installed BunSidLabs on bare-metal btrfs for the first time and wanted to take advantage of snappers capabilities now.
In order to bring things up i stumbled about this handy snapper-gui.
Since it is made for (L/X)Ubuntu, I don`t really wonder why it is not compiling on my system
but asked myself whether or not there might be something similar for debian systems or at least a good Howto on hoe to set up things properly using CLI because I`m feeling a little lost right now and I think/hope there are some more noobs like me in desperate need of some advice.

Thanks in advance,

Neither do we unless you post the actual errors wink

I get this in my Diproton system:

empty@Diproton:~/git/snapper-gui $ python3.5 setup.py install
/usr/lib/python3.5/distutils/dist.py:261: UserWarning: Unknown distribution option: 'entry_points'
  warnings.warn(msg)
running install
error: error in setup.cfg: command 'install' has no such option 'single_version_externally_managed'
1|empty@Diproton:~/git/snapper-gui $

I got past this by using:

sudo apt install python3-{setuptools,dbus}

That let the package be built but I still can't seem to run it:

empty@Diproton:~/git/snapper-gui $ snapper-gui

During handling of the above exception, another exception occurred:

That looks like a DBus permission error and I'm not sure how to fix that in the BunsenLabs desktop, sorry.

Perhaps open an issue on the GitHub page and seek help there?

^Thanks for the fast reply, Head_on_a_Stick!

Actually i got the same error you showed up there.
After installing the packages you mentioned i got it build but can`t seem to get it to work either.
Though the error messages reads like this:

naik@110101:~/bin/snapper-gui$ sudo snapper-gui
Traceback (most recent call last):
  File "/usr/local/bin/snapper-gui", line 11, in <module>

    return self.resolve()
  File "/usr/lib/python3/dist-packages/pkg_resources/__init__.py", line 2297, in resolve
    module = __import__(self.module_name, fromlist=['__name__'], level=0)
  File "/usr/local/lib/python3.5/dist-packages/snappergui/__init__.py", line 5, in <module>
    gi.require_version("GtkSource", "3.0")
  File "/usr/lib/python3/dist-packages/gi/__init__.py", line 118, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace GtkSource not available

which seems to be related to the communication between gtk and python.
I will try to get around this and update this post as soon as i found a solution...

There is also TimeShift. Did anyone maybe test it on Debian?
