2 years, 7 months ago
You remember what memes walked on the Internet about seven years ago? In one of them the client beat out the continuous Internet from technical support and complained of daily gaps. Was and is ridiculous, and it is sad. Put yourself to the place of the engineer of support – yes you will not explain to such client that Earth round!

Now jump to the place of the client and remember hour talk with call center. Long expectations on phone, attempts to receive a handful of useful information … On that party too it seems not strongly strain. Really everything is always so bad? And that conversation was really set, on both ends of a wire the truth people with the highest technical and the patience of job are necessary?

We exploit the free Veeam Backup &Replication version

2 years, 8 months ago
Give at once frankly: nobody likes to pay for software much. And for some there is "a lot of" — it everything that high price of daily lunch. Even so far as concerns professional software for professionals if on the horizon there is slightly less paid competitor with smaller number of functions, it at once draws to itself(himself) set of attention, and in the heads of the amazed public arises question: "Or perhaps in the recognized leader of the market really already search of these functions and to pay for them there is no reason?". As the answer, some vendors start looking for new, relative honest methods of depriving of money at the population, and enter podpisochny services which as a first approximation, allow to pay for software much less.

Other approach to problem — clear understanding, what functionality is necessary at the level of house and/or laboratory use, and what at the level of big corporations. And after the zen will be comprehended, all "house" functionality becomes free, and for the rest ask money.

Today I suggest you to consider the second model, having found out that the Veeam company offers the users on a grant basis and whether so it a little for daily personal use. Even if if from under "personal" looks through small buy-sell office, or prostikhospod, startup which considers that "the bloody vendor" wants too much money for the products.
If doubt that they give really powerful tools, without asking anything in exchange and that in general so happens — welcome under kat.
