Last week (October, 2015) the old friend appealed to me to help. There was at them an accident to accounts department.
We are familiar with the company long ago, we are on friendly terms with the director families years 10. About 1.5 years ago they asked us for the help, but for some reasons refused our services. As a result signed the agreement with the company 1C of the franchisee which began to service them far off. The company assured that everything will be good, for the time being.
But here, once the accountant cannot enter, there is no database, and in 10 days delivery of tax accounting.

In post about backup of physical machines the different modes of backup implemented in Veeam Endpoint Backup FREE were considered. Throughout subject today I will tell slightly in more detail about choice of folders and files for backup in the File level backup method, and also about support of BitLocker and about setup of use of paid connection. Behind all this welcome under kat.
1 year, 11 months ago At last it was succeeded to organize mounting and testing of prototypes of the device of the new version. The device executing only one function – destruction of computers. However, we will not be limited only to computers, the device is capable to put out of action practically any equipment the equipped USB Host the interface. For example, I on table have oscillograph with the USB interface (but it still is useful), practically all smartphones support the USB OTG mode, TV, routers, modems, etc.

Big failures in online projects happen seldom. And in big projects — is even more rare. Of course, the system is more difficult, the probability of error is higher. One hour of idle time of large systems, especially social networks, runs into money and therefore in big projects many efforts on accident prevention and decrease in negative effect for users are used. But sometimes whether stars develop in special combination, whether Murphy's law finds real force, and big accidents nevertheless happen. In the history of Schoolmates the largest failure has happened on April 4, 2013: within three days the project was entirely or is partially disabled. That then has occurred, for what reasons and as we fought against it, there will be our story.

That when planning resources for Veeam Backup &Replication people could estimate, how many place it will be required in repository for backup of the virtual computer, the calculator simulator of restore points of Restore Point Simulator (RPS) has been created in due time.
But as periodically it is necessary to hear from users "And why \why here this value?", today I will give some explanations about parameters of input and I will tell, values by default from where have undertaken. Behind details welcome under kat.

In process of growth of popularity of technologies of virtualization and cloud computing also appropriate means of backup develop. We already acquainted readers with opportunities of Symantec Backup Exec 15 – simple software of backup in use and the data recovery for virtual, physical and cloudy environments integrated with the software of VMware and Hyper-V told about specifics of licensing of new product and migration.
In July, 2015 Symantec has let out the Backup Exec 15 Feature Pack 1 (FP1) service pack. Thanks to it BE 15 has found new qualities. Besides, as practice shows, not all users of Backup Exec 15 are familiar with specific features of this product. So, about everything one after another. Let's begin with FP1 innovations.

"How many times repeated to the world" that backup as end in itself does not make practical sense – and it has that, of course, if from a backup copy perhaps quickly, correctly and easily to be recovered. Therefore recovery of the physical machine from the backup copy created by means of Veeam Endpoint Backup FREE will become a subject of my today's post, throughout previous. As you, probably, already assumed, options of recovery are closely connected with backup settings: needless to say, to recover the machine entirely it will not turn out if there were zabekaplena, say, only the user folders. Let's consider these options in more detail for what welcome under kat.

Not so long ago the most interesting research of "A Large-Scale Study of Flash Memory Failures in the Field" behind authorship of Qiang Wu and Sanjev Kumar from Facebook, and also Justin Meza and Onur Mutlu from Carnegie Mellon Universityhas been published. The main outputs from article with small comments are lower.
Now, when flash drives are very actively used as high-performance replacement to hard drives, reliability plays them more and more important role. Failures of chips can lead to idle times and even data loss. For development of understanding of processes of change of reliability flash memory in actual practice of the loaded project the research provided in the discussed article has been conducted.
Authors have collected extensive statistics in four years of operation of flash drives in Facebook data-centers.
As many for certain know, Facebook long time was the best (and the basic) the client of the Fusuion-IO company (SANdisk is now bought), which has started releasing one of the first PCI-e flash drives.
As a result of the carried-out analysis of collected data, number of interesting outputs has been made:
It is a lot of copies broken-down in a question of that, to properly check the e-mail address (for example, habrahabr.ru/post/175329), but allow to provide you a little statistics from the real project.
