March 31 is an unofficial holiday - Day Reserve copy(World Backup Day). This day was established to attract public attention to the issues of ensuring the safety of information and protection against data loss.
A backup is a backup copy of all the files you need, for example, emails, documents, videos, family photos, etc. Instead of storing all important information on one medium, which cannot be guaranteed to be 100% reliable, another copy is placed on additional media.
So as not to lose important information, you just need to set up backup once. As an additional storage medium for backing up your most important data, you can use either a physical disk (external drive) or cloud storage data on the Internet. If you have never made a backup before, March 31 is the best day to do it for the first time. Who chose this date and why?
Today there are many different approaches and programs that provide a competent backup system. How to organize this process is up to each user.
But you shouldn’t let the situation take its course and assume that this problem will never affect you. Everything is possible - from man-made problems, technical failures and equipment failure to accidental deletion of files or intrusion malicious virus.
Protect yourself from force majeure and back up your important information today!
Backup is the process of creating a copy of data on a medium designed to restore information if the original medium is damaged. Today, people all over the world - system administrators, Enikey specialists and ordinary users - are celebrating World Backup Day. The date was not chosen by chance - some of the viruses are activated on April 1, leaving unprotected users in the cold on April Fools' Day.
How did bloggers celebrate backup day?

I remembered the oath of the defender of information:
International Backup Day (in their barbarian – ) is held annually on March 31st. Backup Day was stirred up by Reddit users, and since cases of information loss on April 1 are widely known (Such cute “jokes”. It’s just some kind of holiday!) - exists whole group April Fools' viruses, which are activated on this day for greater joy on one of our main and favorite national holidays, and therefore it was no coincidence that this labor holiday, like a subbotnik, was scheduled for March 31, and not April 22 (for slow-witted people or those who are not young I found it - it’s Ilyich’s birthday and the festive communist subbotnik on this occasion)
Protect yourself
Back up your important information today!
“I solemnly swear on March 31st to make a backup of all the documents and valuable memories I need.”
In addition, I will tell my friends and family about International Backup Day - a friend will not leave a friend without a backup!

I made a selection of pictures and facts about backup:
The computer froze, HDD died, what should I do?! Did you make a backup (and did you move away from it)? What, it might explode?!!
There is a play on words here: backup is a backup, back up is to retreat.
We make backup copies of data on sticky notes. Because they don't freeze.
I didn't make a backup...
My backup crashed!!! What a blessing that the data was saved on the main copy!
Jim simply drew a backup of his PC.
A little from English Wikipedia:
On May 5, 1996, during a fire at the headquarters of Crédit Lyonnais, the largest bank in Paris, system administrators ran into a burning building to rescue tape backups since the copies were physically located in the same building. Data from computers was copied onto magnetic tapes, which were stored there, on the computers, until the next backup. Backups were made every day, with the exception of Friday, because Friday backup took place on Sunday. And it’s bad luck that the fire happened on Saturday. http://catless.ncl.ac.uk/risks/18.14.html#subj3 - Crédit Lyonnais errors are discussed here and all sorts of backup tips are provided.
Between 2005 and 2006, the human rights organization Privacy Rights Clearinghouse recorded 16 cases of abduction or disappearance. backup copies. Among the affected organizations were: Bank of America, Ameritrade, Citigroup and Time Warner.
On January 3, 2008, the mail server of the largest Scandinavian provider, the telecommunications company TeliaSonera, crashed. To their horror, they had to discover that the last working backup had the date: December 15, 2007. This affected 300,000 user accounts. mail accounts.
February 27, 2011 due to a failure software in Gmail, 0.02% of users lost all their mail. After a few hours, the data was restored from a backup copy and the messages did not disappear into oblivion.

organized a competition!
Today, March 31st, is International Backup Day. It was no coincidence that Backup Day was set for March 31, because there is a whole group of April Fools’ viruses that play their “pranks” on April Fool’s Day.
There can be many reasons for losing important information. According to the study, 78% of cases are caused by hardware failure, 11% human error, 7% software errors, 2% Computer viruses, 1% Natural disasters, 1% Other reasons.
Another sad statistic. 5% hard drives fails in the first year. Then for 2-3 years they work relatively stably (probability of failure is 1.5%), and after the third year the probability is already 11-12%.
Let's celebrate backup day by making copies of your important data today, without putting it off, as usual, “until tomorrow.”

How much has happened, how much has been achieved!
I wish you many warm words,
So that there is happiness and there is love,

The sun was shining everywhere above you!
Time rushes by without looking back,
And year after year runs.

And they contain rams and shrimps
You would be a better captain
Didn't get out of the round-the-world trip!
Find adventures
I wish on this day
For your favorite butt
If only you weren't lazy.
You are a young woman
And so serious
When you flutter one eyelash,
The men will fall like birds.
Black silk panties
To seduce men!
And in general - bold outfits
Buy it on your birthday! I wish you stone health,
Like a miracle wall in Asia,
I wish you a fiery man,
Love for all time.
I wish you emoticons on your faces
And sincere kind speeches,
I wish I could be a good girl during the day,
And at night it’s hot!
I want to drive a sports car
Breathe with buffalo health,
Be in the mood, in the mood
Perform the Herculean feat!
Not a man, but a tiger!
All desires in a moment
They will come true soon.
Just believe it!
Happy Birthday to You,
May there be happiness for years to come,
All dreams come true,
And every day in great love!
Enormous wealth
So that no one forgets you,
And my soul was warm,
The rest doesn't matter!
We wish you simple happiness
And quiet earthly joy.
May life's bad weather
Always bypassed.
As always, store it with care.
There are beautiful features in my soul.
As before, give generously to everyone.
Fire of spiritual warmth.
True Woman with a big letter
Sweet, cheerful, with a kind soul.

There are many wishes in the world,
You can't count them all.
I just congratulate you
I love it the way it is.
Be beautiful all the time:
Both with soul and with yourself.
Be loved all the time:
Both in winter and in spring.
I wish you all the best and bright thoughts
Let the past grievances go away
Get rid of them quietly
Forgiving and letting go is not easy work
But every morning early at dawn
Try to forgive someone
Because the sun is shining brightly in the sky,
Start giving thanks in your life
She's sending you lessons,
So that you become more responsive, wiser
But he only hears offensive reproaches,
Either there is no money, then there are no true friends
You thank your life for everything
Because you don't know war,
For sitting at the computer.
Because someone needs you
Because you have a family and children,
And if not, ask her.
She's not deaf and she'll answer you,
Forgiving you for your previous whining
Do you want to be rich? Dream!
The money will come to you on its own
Do you want to be happy? Go for it!
Learn to trust, forgive, love
Imagine your life without fears
Without fears, without reproaches and insults
Free yourself from empty doubts
You will see that fortunately the path is open
Leave your past alone!
It's gone and can't be brought back
Think about your fate today
And draw a bright path in your thoughts
The whole world cannot be rebuilt under one,
But you can rebuild the world inside
And it's better to trust than to argue forever
And it's better to find than not to find
Life gives you invaluable advice
What is, might not have been
Introduced? For every ray of light
Learn to be grateful for your life
Dance barefoot on shards of glass
Dance, hugging the slanting rains,
Dance so that your life is not wasted,
And sing in unison with the young winds.
Love! love freely and warmly!
Love so that your heart burns everything inside,
Without feeling pain and fear in the blood,
Love that it covers both of your heads!
Live! Break and live again!
Take your wings from the wide road!
Don’t tear your soul apart with empty words.
Look to the skies and think about God.
Dance! barefoot on shards of glass.
Dance! under the cover of the raging night.
Dance! as if there is not a drop of evil in life.
Dance! tearing the whole world to shreds.
Smile as often as possible.
And give your joy to everyone.
Wake up with a light smile
Betting in the clouds with happiness.
And take care of joy in your heart.
Don't be shy to give a smile
Help me believe in miracles.
Enjoy every moment,
Just look around.
When suddenly it’s bad, smile
And joy will be found along the way.
Try, just smile.
Reveal yourself with all your heart.
And try to be happy
“I love you forever” - say.
Life is so beautiful, smile.
And the world will laugh with you.
Smile as often as possible.
Greet every day with a smile.
Irina, bringing happiness, peace,
We are proud to know you and be friends with you.
And we are happy about the golden autumn times
Congratulations on your birthday, being close to you.
Kind and always with a smile on your lips.
To catch you in your thoughts, not in your dreams
Often we can, but carefully:
There is no way to disturb your peace!
Your delicacy and calmness are strength!
And it’s hard to imagine asking for anything.
Rather, you help others, lovingly,
Forgetting myself for a while.
For this we especially appreciate
And on your birthday we want you unbearably
Shower flowers, confess your love,
Give at least a piece of your soul in love!
And wish you magical and wonderful meetings -
Everything for you, for the lovely Irina!
So be you dearly loved by everyone,
Uniquely happy in life!
Always be cheerful and carefree,
Give up your family affairs
Oh! What a woman went!
Don't forget your makeup, of course.
Even if you're going home
So that everyone you meet involuntarily thinks -
Oh! What a Lady - my God!
Let happiness be a downpour and an avalanche,
A whirlpool, a whirlpool, a river.
What is happiness? -Be loved.
So be loved like no other!
Happy birthday!
Happy birthday, dear.
Congratulations from the bottom of our hearts.

And beautiful - just like now.
May good luck accompany you
Every day and every hour.
To spite your enemies - live beautifully!
In spite of the years - be young!
Drive away all misfortunes from home
And everything will come by itself.
Suddenly you will become prosperous,
Lucky, always lucky.
The reward awaits you, success!
I wish you to be the happiest of all!
Many years have passed since then.

Smiles and flowers

Dreams will come true!

International Backup Day or Backup Day is held annually on March 31st.
Backup- this is the creation of a copy of data on a medium (hard drive, flash card, CD-ROM and other media) designed to restore data in case of damage or loss on the main medium.
In this age of computers and electronics, ensuring the safety of valuable information is becoming increasingly important. The loss of financial information, databases or website information can lead to big problems in the organization and significantly hit the wallet. Yes, and each individual user home computer, communicator or simple cell phone can get a lot of grief by losing the necessary data - from favorite photos, home videos or necessary articles to contact numbers and addresses.
Therefore, International Backup Day is intended to attract public attention to the issues of ensuring the preservation of information, as well as to spread awareness about the need to protect against data loss.
Backup Day was established on the initiative of users of the social news site Reddit and it was no coincidence that it was set for March 31st. In the computer environment, there are known cases of information loss on April 1 (those are the “jokes”) - there is even a whole group of April Fools’ viruses that are activated on this day. The result of their merciless action is a system failure or loss of information.
Today there are many different approaches, tools and programs that provide a competent backup system. How to organize this process is up to each user. You can take appropriate actions yourself or contact specialists on this issue.
The statistics prepared by the online backup service Backblaze for such a significant date are simply amazing. It turns out that 35% of all users have NEVER backed up their data! 51% of users make backups once a year or less! And only about 8% of users make backups daily, 15% - once a week, 30% - once a month! It’s interesting that over time, the percentage of users who make backups does not change at all, i.e. people don't want to study at all own mistakes. As expected, the need for backup is understood by more experienced users who have higher education and sufficient experience working with computer equipment.
You should not let the situation take its course and assume that this problem will never affect you. Everything is possible - from man-made problems, technical failures and equipment failure to accidental deletion of files or the introduction of a malicious virus, and sometimes simply losing your phone.
Beginning users, and especially women, come to the idea of backing up important data, as a rule, only after it has been lost. Let's not wait, according to the great Russian tradition, for the roast rooster to peck, and let's start backing up at least the most important data today. Therefore, today’s holiday can be celebrated very in a simple way- create a backup copy of your data from your computer and save it on a reliable resource. And, of course, tell all your friends and acquaintances about this so that they do the same.
Protect yourself from force majeure by backing up important information today!
SOLEMN OATH FOR INTERNATIONAL BACKUP DAY
I solemnly swear on March 31st to make a backup of all the documents and valuable memories I need. In addition, I will tell my friends and family about International Backup Day - a friend will not leave a friend without a backup!
I SWEAR!
SO HOW DO I MAKE A BACKUP?
Most people choose one of two methods to backup their files: saving copies to external drive, or to some online storage.
It's really simple and you only need to set up the process once!
DISCLAIMER: Although this process is very simple, we are not responsible for the loss of any data. Make sure you read everything carefully and then everything should work out!
BACKUP TO USB DRIVE
You will need external hard disk, preferably larger than your computer's hard drive.
The good news is that they are inexpensive!
WINDOWS 7
Click the Start button.
Enter the word “backup” into the search bar.
Click on Backup and Restore.
Select “Set up Backup”.
When Windows has finished preparing, select your external drive and click Next.
Select “Let Windows Choose” and click Next.
If you want, you can choose which one Windows time will backup your files by clicking “Change Backup Schedule”. The more often the better!
After that, click “Save settings and run backup”.
That's all! Now Windows will automatically make backups. Make sure your hard drive is still connected; if you use a laptop, set yourself a reminder to plug it in periodically.
WINDOWS 8
Open start screen and start typing “file history settings”.
Select “File History Settings” from the search results.
Select “Select a drive”.
Select your external drive from the list provided.
Click “Turn on”.
It's that simple. Now Windows will automatically make backups. Make sure your hard drive remains on or plug it in as often as possible.
Congratulations on setting up your first backup!
MAC
First, connect your USB drive. After that, follow the instructions below to start automatically backing up your Mac!
**WARNING:** Make sure your new USB drive is completely clean! Time Machine requires *clean disk*, keep that in mind. If this new disk or cleaning it doesn't bother you, read on!
Open the menu (top left of your screen) and select System Preferences.
Click “Time Machine”.
Click “Select Disk”.
Select your USB drive from the list provided and click “Use Disk”.
That's all! Now your Mac will back up your data automatically. If you use a MacBook, be sure to connect your hard drive to it regularly so it can save files!
LINUX
Every Linux distribution offers various tools to backup your data. We've posted the instructions for Ubuntu below.
Open the HUD (click the Ubuntu button in the Dash) and type “Backup”.
Click on the search result “Backup”.
Click on “Just show my backup settings”.
Activate “Automatic backups”.
Choose the location to store your backup on the tab “Storage” (your external drive).
Choose how often to backup on the “Schedule” tab. The more often, the better!
Click on “Back Up Now” on the tab “Overview” to start backing up.
That was easy. Ubuntu will backup all your files automatically fromnow on. Make sure you leave your hard drive plugged in - or at least plug it in often.
Congratulations on setting up your first backup!
BACKUP IN ONLINE STORAGE
An easy way to save your files online is to use OneDrive, Dropbox, or Google Drive to backup the most important data you are currently working on.
These online services are not that powerful and only back up one folder on your computer. However, this is a great option for students or workers who need to reliably protect their most important data.
BACKUP YOUR ENTIRE COMPUTER
If you want to create a backup purchase of EVERYTHING (bravo!) - pay attention to this review - it can help you choose the most suitable service for you.
Backup rule "3-2-1"
It is believed that the “3-2-1” backup rule was first described by Peter Krogh in his book “Digital Asset Management for Photographers.” And this is probably not surprising, since the loss of a personal archive means complete disaster for a professional photographer, and he simply must adhere to a backup strategy that is guaranteed to protect him from data loss.
So, the “3-2-1” rule states that to ensure reliable data storage, you must have at least:
- THREE backups,
- which should be stored in TWO various physical storage formats,
- and ONE from copies must be transferred to off-site storage
"Three different copies" means "three copies stored in three physically different locations." (Two different folders, located on one physical disk are considered to be located in one place). I won't get into the math, but as you increase the number of copies, (assuming the physical characteristics of the storage devices are the same and the threats to those devices are statistically independent) the probability of failure increases linearly and the reliability of storage increases according to a power function. That is, when you make three copies instead of one, you get a tripling of the probability of failure of a given set of copies with a cubic increase in reliability. In real life, this makes data stored in triplicate virtually “indestructible,” although you may have to replace failed drives a little more often simply because there are more of them in the aggregate.
However, alas, it is in real life that there is often a statistical dependence of threats. For example, when an electromagnetic pulse occurs in the office power circuit, it equally affects all disks at once. And, if one disk fails, then, most likely, the other two will also fail (due to the homogeneous nature of the impact of the pulse on typical commercially produced disks, which have identical requirements for the quality of the power supply).
Why do you need three copies and not two? Because in real life, very often, threats to two copies of data turn out to be statistically dependent due to the logical organization of the backup procedure. For example, consider RAID1 (or a disk array with “mirroring”). If a virus infects a file on one disk of the array, the second copy on the mirror disk is immediately infected. Likewise, if replication is configured, the replica will also be instantly corrupted by the virus. Even if a full backup is simply created daily, it will also be infected if the administrator does not notice the infection of the source data within a day. In general: two copies will not be enough to restore information in all cases where the time to identify and respond to damage to the original data exceeds the period between adjacent tasks of copying/replicating/mirroring this data.
To ensure even greater statistical independence of threats, it is recommended that data be recorded in at least two different physical formats. For example, if you save data on a DVD (optical recording of information), then it will not be affected by the electromagnetic pulse described earlier. Even if the DVD drive fails, the optical storage media themselves will save your data. Other examples of a statistically dependent threat could be a long-term critical increase in temperature due to a failed air conditioner in a server room or a fire in the office, which, of course, has an absolutely uniform effect on all copies stored inside the office.
Thus, storing copies in different physical formats is intended to reduce the likelihood of simultaneous data loss of all copies due to uniform impact.
In fact, the third point, storing one copy outside the office, solves the same problem (reducing the statistical dependence of threats to different copies of data), only through the geographical distribution of storage locations. A theft or fire in an office may result in the loss of all copies stored there, but a fire or theft in one office will not lead to a fire or theft in another geographically isolated office, making these threats at different offices statistically independent.
What about storing data in the cloud? Can this be considered a backup replacement? Obviously not. This is simply an alternative place to store data or backups of it, and, by the way, a good candidate for off-site backup storage. However, we must always remember that data can be lost in the cloud just like in any other place.
At the same time, the undoubted advantage of cloud providers is that the backup process is greatly simplified. The administrator does not need to buy and configure complex storage systems or “mess around” with changing tapes. Often, cloud storage is transparently expanded at the client’s request, that is, it does not have a physical size limit for the client (the limitation for the client is rather financial in nature), which also has its advantages over storage systems, the free space on which can “suddenly” run out.
In fact, cloud storage of backup copies of copies is an alternative to tapes, since data from it, compared to local disk storage, is retrieved with a certain delay (which depends on the channel width and the provider’s tariff, since, usually, the lower the tariff in cost, the slower it will be data retrieval speed).
Is it always necessary to strictly follow the “3-2-1” rule? No, it all depends on the value of your data, on the one hand, and the criticality (cost of potential damage) and the likelihood of threats to the data, on the other hand. Any protection should not exceed the cost of the protected object. Therefore, if you store data that is not particularly valuable, or the threats are low critical or unlikely, you can partially implement the “3-2-1” rule. The main thing is to still create a matrix of threats to data (that is, make a list of all possible threats, assess their likelihood and criticality) and carry out the process of their de-actualization (that is, for each threat either write in the table either “de-actualized by such and such a technical measure” or “recognize not relevant from the point of view of the nature of the company's business"). After working through the threat matrix, it will become clear to what extent the 3-2-1 rule should be implemented, and what budget will ultimately be required.
