Backup-Simple to do?

I prepared myself to do training for the members editorial boards of two journals issued by one institute of economic sciences.

I came to the premises where I was supposed to do training, but I noticed that people who entered data in the system dedicated to on line publishing were shocked and confused. “Everything is gone!”, said one of them.  “What has gone?”, I asked.  “The data we entered in the last two months!”, she replied sadly.  I started to examine what has happened and discovered that some bad backup was restored over our virtual machine hosted on their server.  “Hmm, did anyone restored some wrong backup?”, I asked.  ” I do not know how to do that and even our administrator is away. He left a couple of weeks ago.”, she sad hopelessly.  Well, another person was invited  to examine what has happened and we determined by checking logs and possible scenarios and we have found that former system administrator assumed that so-called bare-metal backup was sufficient. In addition, he did not check whether back was complete or not and what software vendor suggests to perform backup of guests on Hyper-V. Well, too much mistakes resulted in complete loss of data that two persons entered in the period of two months.

So, when you plan hosting and backup of your data please check carefully documentation, test your methods of backup and after checking of various possible disaster scenarios implement it on production (virtual) machine with open access application and samples of data entered.
