(SOLVED)How do I make a system snapshot?

Hi,
The latests udev scare has shown me two things: you can rely on the community to fix this (thanks Tobias!) and a good backup/snapshot is worth its wheight in gold.
What manual do I read/study/understand to make a system snapshot before upgrading? I rely on the fallback now, but... the current system (the one that does not work that well) will become the ... fallback after update and that's not a good prospect...unless I'm mistaken!
Thank you, I hope my question does not raise any storms.

Hi everyone,
@karol : indeed, this is the "painful spot" - it seems to be solved, so an update is in order of course...just want to keep the "furniture safe" so to speak
@ tomk : no offense taken, but, I stil consider myself a newbe (but I am a newbe that IS willing to learn...), so the question is "what to learn and what to learn first?", okay, so there are some things you mentionned I need to learn, but Linux is NOT just a hobby for me. I do not have any other system (like Mac or windows) - there just is ... Linux.
@ ngoonee : I dont know yet what the fallback is, but there's just one word for it right now : lifesaver! Arch is great, there IS a fallback
Edit : Okay, some options have come up...in the answers posted...including one post elswhere from one Enlightened Spirit - who also has my profound gratitude.
I have understood (from the stuff I read) that the fallback is "merely" (using this word cautiously) an all-in-one package while the standard kernel is a fine tuned set. Hence, since there is "just what is needed", there is nothing to "fall back" on...the difference in size (1.4Mb - 7.9Mb) tells tales.
I looked into rsync too, okay, that, in combo with a weekly cron job and one to be run before updates, should be all I need to be secure...
I can safely say that this thread can be closed...and marked as solved as requested in this thread https://bbs.archlinux.org/viewtopic.php?id=50161...
Editting the subject line next time round!
Closing edit : marking this thread as solved with gratitude to all that helped, and showed me what to learn next!

  • [SOLVED] How can I make my system secure as much as i want it too

    Is arch already secure by default. What should i do to make it secure as other distros?

    Which distros do you mean? Arch can be made more secure surely. But you have always to remember that you will never be completely safe.

  • How do I make a composite snapshot in CS5?

    How do I do a composite snapshot using Photoshop CS5.  I know it can be done using CS6, but am not having any luck using Control + shift + alt + E?

    Shift+Ctrl+Alt+E is the shortcut for Stamp Visible Layers. It does not always work it depends on things. For example if the top layer is the current target and its visibility is off.  Shift+Ctrl+Alt+E will do nothing.  It also sometimes it adds a new layer and stamps the composite of the visible layers into it. However if the current targeted layer is empty a new layer will not be added instead the composite will be put into the current empty layer targeted.
    I use stamp visible all the time and use it in actions so I create them in a way that always works.  Shortcut Shift+Ctrl+Alt+N+E well that is a cheat. For it is actually two shortcuts Shift+Ctrl+Alt+N followed by Shift+Ctrl+Alt+E.  Add new empty layer without prompt followed by stamp visible layers.  When you add a new empty layer it becomes the Photoshop target. Therefore Shift+Ctrl+Alt+E will always work and the composite will be in the new layer.  In action I usually follow that with Shift+Ctrl+] to move that new layer to the top of the stack.  For where the new layer get added depends on the current target when the layer is added.
    Shift+Ctrl+Alt+N Shift+Ctrl+Alt+E was how you had to do this before I think CS3.  For Before that release Shift+Ctrl+Alt+E would not add a layer. I believe it was in CS3 that Adobe changed the way Shift+Ctrl+Alt+E worked. IMO Adobe didn't do the best job they could have.

    If there is a command line tool then you use Runtime.exec() otherwise you have to use JNI.

  • NoteBook HP 620.How can you make a System Recovery Disk on HP 620 Notebook?

    The HP620 model is possible to recover the system using F11. This utility formats the hard drive and reinstall Windows 7 on the hard drive.
    My question is:
    You can make a copy on a DVD media operating system, such as is done with the Recovery Disk Utility on the desktop models?

    Hi,
    Click the Start Menu, open All Programs and scroll down the list to see if you have a folder called Recovery Manager - if you do, open it and see if it contains an applications called Recovery Disc Creator.  If you have this application, double click it to launch the program which should then guide you through the process of creating a set of Recovery Discs.

  • How can we make SAP system READ ONLY !!!!!

    Hi, we have an SAP R/3 4.6 C Application. We need to take the system for read only state means we don’t want the users to allow any update for the system but they should be able to view the data what they have created. Mean while we don’t want the database to be taken in read only mode as we the administrators or the users might want to update their password information.
    It would be a big help if some one can through some tips on how we achieve this.
    Thanks much in advance.

    Hi
             Please make the database in READ ONLY MODE. This will help. If it is an oracle database then.
    Open a Database in Read-Only Mode
    You can open any database in read-only mode to prevent its data from being modified by user transactions. Read-only mode restricts database access to read-only transactions, which cannot write to the datafiles or to the redo log files.
    Disk writes to other files, such as control files, operating system audit trails, trace files, and alert files, can continue in read-only mode. Temporary tablespaces for sort operations are not affected by the database being open in read-only mode. However, you cannot take permanent tablespaces offline while a database is open in read-only mode. Also, job queues are not available in read-only mode.
    Read-only mode does not restrict database recovery or operations that change the database's state without generating redo data. For example, in read-only mode:
    Datafiles can be taken offline and online
    Offline datafiles and tablespaces can be recovered
    The control file remains available for updates about the state of the database
    One useful application of read-only mode is that standby databases can function as temporary reporting databases
    Opening a Database in Read-Only Mode
    Opening a database in read-only mode enables you to query an open database while eliminating any potential for online data content changes. While opening a database in read-only mode guarantees that datafile and redo log files are not written to, it does not restrict database recovery or operations that change the state of the database without generating redo. For example, you can take datafiles offline or bring them online since these operations do not effect data content.
    If a query against a database in read-only mode uses temporary tablespace, for example to do disk sorts, then the issuer of the query must have a locally managed tablespace assigned as the default temporary tablespace. Otherwise, the query will fail. This is explained in "Creating a Locally Managed Temporary Tablespace".
    Ideally, you open a database in read-only mode when you alternate a standby database between read-only and recovery mode. Be aware that these are mutually exclusive modes.
    The following statement opens a database in read-only mode:
    ALTER DATABASE OPEN READ ONLY;
    You can also open a database in read-write mode as follows:
    ALTER DATABASE OPEN READ WRITE;
    However, read-write is the default mode.

  • [PARTIALLY SOLVED] Wine 3D apps make the system randomly freezes

    Hi!
    Since some months, i can't play longer that one hour on games through wine: xorg locks up the system randomly: i can't switch to a console or close the game with Alt+F4. I can only move the mouse, and the sound is always running. Moreover, I can always connect to the pc through SSH.
    I think it's due to fglrx driver, because with the OSS one, I never freeze so (but I get crap performances, what is not the best to play...).
    Did someone got the same issue and solved it?
    Thanks,
    nob.

    Write bug report to amd, and pray.
    Edit: To not leave the post so cynical.
    AMD's fglrx driver is not that high quality. From personal exprience, it has always caused more problems than good.
    So your only choice is really to a) Write detailed bug to amd, and hope they fix it. b) Use the open source drivers. c) Change GPU

  • [SOLVED] How cat I make an http proxy from ssh?

    Hi.
    I can tunnel to ssh server using this:

    It's working good. I tunneled to the server.
    But I have a problem!
    the created proxy is a Socks v5 proxy. I want to create a http proxy how can i do it?
    Thanks! I waiting for your answers...

    You can't. What you can do is run a local http proxy that uses the ssh-created Socks5 as parent. Example config for polipo:
    daemonise=true
    proxyAddress=127.0.0.1
    proxyName=localhost
    allowedClients=127.0.0.1
    socksParentProxy=localhost:7777
    socksProxyType=socks5
    7777 is an example, use $myport there. The default polipo port is 8123, meaning apps should be configured to use localhost:8123 as proxy.
    Thanks for your help! It's worked very good and my problem is solved.

  • [SOLVED] How do I make AwesomeWM ignore Plasma

    Hi
    I just started using AwesomeWM with KDE. I am trying to get AwesomeWM to ignore Plasma. I found in the AwesomeWM Lua docs that a client (window) has a function 'unmanage' this sounds like what I need but I am having trouble getting it to work as I expect. The first thing I expect is that awful.client.moveresize function should not resize Plasma (panel or desktop). I should also not be able to close or minimize plasma. I tried adding the unmanage function to the awful.rules.rules table. This does not do what I expect.
    Here is what I tried:
    -- Try match name
    awful.rules.rules = {
    { rule = { name = "plasma-desktop"}, callback client.unmanage}}
    -- Try match class and maximise
    { rule = { class = "Plasma"}, properties = { type = "desktop",
    maximised_vertical = true,
    maximised_horizontal = true,}}
    Can this be done without having to learn Lua?
    PS: In case anyone is wondering, I am using Plasma because I like the notes plasmoid and the folder view. I also like being able to just right click and change wallpaper quickly or add widget. I also like how plasma looks (Gaia recycled theme). I couldn't get Unity 2D working.
    Last edited by lunamystry (2011-11-08 15:56:25)

    I think I solved it. I found you can use Hooks (awful.hooks). This is a bit of a trial and error at the moment (I have tried it, and I am now waiting for the error)
    function unmanage_plasma(c)
    If c.name:find("plasma") and c.type ~= "dock" then
    c:unmanage()
    end
    end
    awful.hooks.focus.register(unmanage_plasma)
    This seems to be working. I tried matching "plasma-desktop" that doesn't work. I don't know why. I also couldn't get client.add_signal("focus", unmanage_plasma) to work. I think using the focus hook may be causing my PC to freeze (or rather become unresponsive) randomly though. I am gonna maybe look for awesome docs that describe the hooks. I haven't found em yet.
    Hope this helps someone.

  • How do I make the system clock visible on all screens - including when I am in full screen mode

    New to the Mac OS . . . I want a clock that persists.  Yes I can mouse near the top and see the clock but I have to move the cursor each time I want to see the clock.
    I tried a few floating clocks - but none of the ones I tried are visible in full screen mode.
    Is there a setting in Mavericks that will make the clock visible all the time?
    Thanks.

    Your best bet might be to set up the clock in Dashboard so you just have to press F12 to see it and dismiss it, even in full screen apps, without having to move your cursor.

    I bought an IDE-USB Adapter and connected a DVD to the Netbook. But the device is not found even by the BIOS, too.
    So I can not install the System. In addition there will be no BIOS update available for LINUX to detect DVD drives if this is the problem.
    How can I make my Recovery DVD run on my Lenovo Ideapad S10e?
    Solved!
    Go to Solution.

    You use a normal 5 1/4 " DVD/CD drive,.it needs 12V dc did you powered the drive... ?
    So the adapter is not recognized, thats bad ....the usb-ide adapter is defective....
    The second question is... 
    Linux cant use any .exe files ...its not windows... thats normal...
    so what will you install on it ?
    Biosupdate ? is the only one .. i think.. but that is a problem for lenovo... i didnt see an biosupdater under linux
    Why you buy those expensive ide-usb adapter ?
    you can get a slimline cd usb drive is available for 25 $ (or 25€) on online shopper...
    and you dont need a power adapter ...
