Software and Tools - Backups

One of the most important things you can do after you secure your device is to make regular backups and just as important is to test your backups.

Why backup?

• Hard drives fail.  It doesn't matter how new the drive is or even if it is a SSD they will fail sooner or later;
• You lose your device or it is stolen;
• You drop your device and now it does not work;
• When you patch or update your operating system it fails.  It doesn't matter the O/S you are using, I have had failed Linux updates and it required me to rebuild the machine;
• You migrate to a new device and want all the files on the old machine moved to the new machine;
• You finger slips and you accidentally delete an important file/directory; 
• There is a disaster (ie. fire or flood);
• Your device(s) infected with a virus or a trojan.  Again, it doesn't matter the O/S you are using, there are nasty programs out there that works in Windows, Linux and OS/X.

If one or more of the above happens you will need a backup so that your important documents are available to you when you rebuild the device or copy to a new device.  I have had people come to me with dead and dying devices asking if I can pull off their data and they have not made any backups.  Too often I cannot recover all of their files and important documents, images, videos are lost and they don't have any backups.

Things to think about

How often do you backup? 

• That all depends on your personal preferences and how many documents you are adding to your device;
• If you don't create very many then it may be safe to backup infrequently (monthly); 
• If you create a lot of files (like scanning family photos), then frequent backups (daily) may be a good thing;
• Once you set a schedule stick to it.  I put up a recurring reminder in Google calendar to remind me of when backups should be run.  Also you can set up a recurring task in Windows and Linux (cron) to run your backup scripts on a set schedule.

How many copies do you want to keep?  

• Again this is a personal preference, but, multiple full backups is a good thing just in case one fails for some reason; 
• An option here is a monthly full backup and then weekly backups of new/changed (differential backups) files;
• Another reason as backups may fail and if you have only one copy then you have nothing to go back to.  I know this happens as decades ago when at work we were doing a DRP (Disaster Recovery Plan) exercise at work and one of the corporate backup tapes failed.  It wasn't a major problem as we did keep multiple backups and restored from an older image;

Off-site location for your backups?  

• It doesn't matter if you have a good set of backups if you cannot get access to your site;
• How secure is the off-site.  If you have sensitive information you don't want anyone getting access to the backup;
• You should also figure out who should have access to your backups and let them know where it is and how they can get access to the backups if required;

Media for backups.  

• Decades ago floppies were the media, then CDs followed by USB drives;
• When you backup make sure that the tools, hardware and software is there to allow you to read the backups.  An example of this is some time ago I had to pull off backups from my father-in-law 3.5" floppy drives as he didn't have a floppy drive in his machine.  We were lucky in that I have an external 3.5" USB floppy drive for this and it was set up in Linux.  I also have an external CD drive and a blu-ray drive (call me paranoid) so I can pull files from backups in that format;
• To the cloud.  Don't depend on that as your main backup as it may not be there when you need it.  I like Google drive for a secondary backup myself and the bonus is that the files I put there are available anywhere I have a web browser (and the firewall allows access).  With the various sites getting hacked I also don't keep files there that are sensitive and when I do put up a file of that nature I use encryption on the file/directory.  I also have a small script using GRIVE in Linux to pull a backup from GOOGLE drive to my machine.

Software and file format for backups.  

• Over time operating systems do change and the software that did the original backup may not run on your new device and the new devices may not even be able to read your backups;
• I tend to work with the lowest common denominator for backups that does work across platforms.  I prefer to use "ZIP" files as I know Windows and Linux both can work with that file format.  I assume OS/X will be able to read them too, but, I don't use that operating system so I am not 100% sure;
• On my Linux machine I am partial to KBACKUP.  It is fairly easy to set up and use and it stores the files in a format that I can open in an Linux distro and Windows;
• On my Windows box I use a simple XCOPY routine.  It isn't pretty, but, it works and the files are in a format that my Linux machines can read;
• For my Android devices they get backed up to Google drive;
• Several times a year I take one of my backups and plug it into a different machine to see if it is readable and I can pull one or more files off the backup.  Make sure what is backed up can be restored!  It is also a quick and easy test to see if your restore steps work and if there is anything else you should be doing when restoring from a backup;

When you restore.

• If the restore is due to a virus or a trojan I strongly recommend that you don't ever use your backups until you have a clean and patched machine.  If the machine is still infected and the media you are using can be written to you don't want those backup files corrupted;
• Make a checklist of what you need to do the restore and the steps performed when doing a restore.  This includes steps on how to verify that the restore worked;

Software and Tools - Browsers

This is the second in a group of blogs on software, tools and repositories.  One of the main tools I use and I suspect the majority of people is a web browser.  There are a number of great browsers out there and the one you use and like depends on your personal preferences (and biases).  For me since I run a Windows laptop (gaming), Android (tablets and phones) and Linux (laptops and netbook) I prefer Firefox and Chrome.  They run equally well on a cell phone right up to the laptop I am composing this blog on.  The Windows laptop (Windows 10) has Edge on, but I don't run it.  I may be biased, but, I don't trust the security on it and how much it is reporting back to MS about my searches and browsing habits.  I know Chrome and Firefox does do some reporting, but, so far they haven't abused my trust there.

This won't be all inclusive, but, a quick tour of my basic setup and hopefully will give you an idea of what they look like and a couple of things I added to assist me and secure my browsing.

If you use Windows click on Firefox if you want to go to the Mozilla site,  click on Chrome if you want to go to the Chrome site.  If you are using Android it is in the Play store and for just about every distribution of Linux it is part of the repositories that you can install (for me that is Synaptic).

For the rest of this blog the screen shots are from my Linux machine, but, Android and Windows have a similar layout and look-and-feel.  For all of the screenshots I used KSnapshot.  Gwenview is used for quick-and-dirty edits (like rotate, resize and rename).  Google Drive is used to store all of my blog images and the GRIVE tool syncs that up for me (with my writing a BASH script front-end, my previous BLOG on that).

Firefox

Once you install Firefox and launch it you will get a screen something like below.

It is a rather plain and simple screen.  This is my personal preference as I don't like or want a lot of clutter.  I have turned off the menu bar, bookmark toolbar and the status bar.

I did add a few extensions (from the Mozilla site) for the status bar and for shutting down those annoying ads.

My Plugins are default to my Linux distro.  When there are bug fixes I use Synaptic to update when they are available.  I still have Flash installed, as much as I hate it for the security holes I still need it for accessing corporate materials when I log into the company site.

To see preferences click on the icon at the top right (looks like a hamburger) and click on the preferences icon (looks like a cog).  You will see a number of options that you can click on and are presented with a variety of settings.  On content I turned off the option to play DRM protected content and to block pop-up windows.  I also changed the font to Arial as I find that easier on my eyes.

For privacy I turned it up to as high as I can go.  I know sites can still snoop, but, I want them to know if they want my information they should ask me first.

For security I also have that set to maximum.

For good measure I use  uBlock Origin to shut down as much of the annoying ads and tracking when I do surf.  I turn it off for sites that respect me and don't flood me with annoying ads.  To see what the dashboard looks like you will need to keep on reading as it is in the Chrome section.

To summarize my settings:

• Check to see if Firefox is my default browser;
• Show blank page at start;
• Search right now defaults to Google, I did disable Bing and Yahoo;
• Disable play DRM;
• Enable pop-up protection;
• Privacy tracking on for private windows;
• Never remember history;
• Security, Warn & block all turned on!
• Sync bookmarks, I have that turned on so it is easy to keep phone, tablet and laptops synced to the same set of bookmarks;
• Downloads, ask me where to save; 
• uBlock Origin, set up to hide as much crap as possible.  Good sites I open up;
• Advanced I left at their defaults. 

Chrome

My other browser is Chrome.  There are times that sites have problems with Firefox and I use that.  It is also set up to link to my personal Google calendar and to use Google Docs.  Part of the time I run it for Facebook to chat with family and post various updates and use Firefox for general web browsing and gaming (Runescape).   Like Firefox I have a minimal screen display, I really don't like clutter.

To go to your settings click the vertical ... on the top right side, then click on settings.

By default the advanced settings are not displayed, scroll down to the bottom and click on +Show advanced settings.  You can see your browsing history, Extensions and Settings.  For privacy you can click on content settings and it pops up a privacy setting screen.

For extensions it will show what you have installed.  At the bottom it has Get more extensions that takes you the Chrome Web Store.  I really suggest you use just that site as you know that Google has done some checks on the quality and security of the extensions.  I know nasty extensions can slip in, but, when found they get yanked PDQ.

Like in Firefox I use uBlock origin.  It is small, light and very configurable.  I used to use Ad-Block, but, when they went to white listing ad sites I dumped it.  I pick what ads are presented to me and I will retain full control of that.

To summarize my settings:

• Show blank page on startup;
• Google is the default search page;
• No 'Guest' browsing;
• Cookies, clears when I shut down Chrome and 3rd party is blocked;
• Let me choose when to run plug-in;
• Do not allow tracking;
• All other content settings at default;
• Downloads, ask me where to save;
• Cloud print is on, I use this only for stuff that isn't sensitive;
• uBlock Origin, set up to hide as much crap as possible.  Good sites I open up;

Summary

Hopefully this is of use and a good starting point for your using either Firefox or Chrome as your main browsers.

Netbook is now Linux

The run with Win10 on the netbook is over.  It was fine, but, I get nervous seeing how many pieces of the system call home for stuff I can't control or turn off.  That and I want to be in control on what gets upgraded and not have it forced on me.  I have been using Linux for years on a variety of machines and it was easy to convert this machine.

The conversion took only an hour and I was up-and-running.  The distro I am using is LUBUNTU and it is quite light on the machine.  I had to make a few changes.  The default word processor and spreadsheet were replaced with LibreOffice.  I prefer it as my Windows laptop runs it and it is easier to work with when I have only one app to keep up-to-date.  Same with GIMP for both machines.  I did remove light-locker and replace it with xscreensaver.  For the system monitor I put on GKRELLM.  To make things work I had to modify the startup via LXSession configuration.  One other quirk was that the touchpad would always start every time I log in and not respect my settings.  That was easy to fix on the start in LXSession.  To do screen captures I had to install Gnome Screenshot as the screen shot key doesn't seem to work.  All of the software is in the Synaptic Package Manager.

Modify startup for my preferences

The best part is it takes about one minute to start up the machine and about 10 seconds to do a complete shutdown.  Windows startup was around 2 minutes and at least a minute for shutdown.

Current screen looks like the image below.

My main screen setup

 Once I got the basics set up I then launched the software updater facility.  It downloaded everything, installed, cleaned up, rebooted and I got the latest version of LUBUNTU.

The only package so far I couldn't find was the driver for my Brother print/scanner.  Upside is that Brother does support Linux and I could download and install the files.  Once there I configured my printer without too much effort.  I had to use the IP address, but, once filled in the printer worked without issue.  The next thing I have to check out is the scanner option.  I also have an Epson Scanner that I want to see if it works on the machine too.  Windows 10 would not support it and I was thinking of buying a new scanner, but, if the netbook recognizes it I can save money by not purchasing a new scanner.
