  Backup

      In this article I will explain the most proper way that a company must keep backup.
  First of all do not hesitate to spend money for the backup procedure and do not
  think that it is waste of money.

      The backup is like a life insurance that you have to pay it even if you do not use it
  at all. A friendly advice from my experience, do not use the backup program of
  windows because 8 to 10 times you cannot restore or backup .

      There are backup devices that can use tapes or you can use network hard disks.
  
  The company must use a hard disk or a tape for each day of the week and at
  the end of each week or at the end of month a backup set of a day MUST move
  outside of the office. So in case that something wrong happened to the company's
  building you will always have a copy of your data. Every second month you can
  replace the backup set you have at home or safe etc with a latest set.
  
  The IT person can always use programs in order to create images of servers
  or the image of virtual machine.

  The Program for images that i have used is Acronis and for normal data backups
  I have use Symantec Backup exec, Yosemite, Baracuda  etc.
  (just a recommendation and do not take it as advertising)

      The backup can save you by keeping files that were deleted accidenly or overwrite
  by mistake (you can use the previous versions tab in properties of a file)
  or infected files by serious viruses like the keylogger.
  Each company that was infected by keylogger spend from 100euros to 700euros
  to unlock the files unless had a good backup to use.

  Concluding this article I would like you to keep in mind what I told you in the beggining....

  "Do not hesitate to spend money for the backup procedure and do not
  think that is waste of money."

  Virus and Antivirus

  Every day over a million files with viruses are transferred via emails and infect our servers and workstations.
  In order to avoid infection we need to have a good and updated Antivirus program installed on our Servers/workstations or install an antivirus on mail server that will filter the infected emails.
  
  The above will protect us only in 85% of virus files the rest of 15% it is users responsibility.
  
  Here some friendly advice that most of the users do not follow:
  
  1. THE ATTACHMENTS WITH .EXE EXTENTION OR MULTIPLE EXTENTIONS SUCH US
  .PDF.EXE ETC ARE VIRUS FILES DO NOT OPEN IT
  
  2. IF YOU RECEIVE AN EMAIL FROM A KNOW RECEIPIENT, DOES NOT MEAN IT IS 100% SURE THAT IS A CLEAN EMAIL.
  
  3. HAVE IN MIND IF YOU OPEN AN INFECTED FILE THAT WILL NOT INFECTED ONLY YOUR PC BUT THE ENTIRE NETWORK WITH SERVERS AND OTHER PC’S.
  
  4. ALWAYS ADVICE YOUR IT DEPARTMENT IN CASE YOU HAVE A SUSPΙCION THAT AN ATTACHMENT MAY BE VIRUS BEFORE YOU OPEN IT .
  
  5. DURING CHRISTMAS OR EASTER SESSION A LOT OF VIRUSES ARE TRANSFERRED WITH ELECTRONIC CARDS DO NOT OPEN THE FILES IF YOU ARE NOT 100% SURE .
  
  Always Have in mind that first a virus created and then the antivirus program found the cure .
  Avoid to download free antivirus programs from web sites because in the most cases is a virus or Trojan or program will cause our pc to run slow.
  Better to buy a professional antivirus program that will save you more money than money that you will lose by destroying your work.
