The importance of the Backup

(versión en español)

A backup is a copy of critical information from a computer system, which is then used to retrieve the information for a possible loss.
Needless to say, the backup’s is one of the most important elements of any business to save data. We at Conekia, do backups regularly and review are being done correctly. In fact, shortly before writing this article, we had to retrieve a copy of one of our internal servers.
What information do you copy?
When we do the copy is to consider what information is being copied and the characteristics of it.
For example, files from a web page do not change unless you update the web. This information is static so we should not take actions such as blocking file to copy. Furthermore, a database changes over time so that when we do the backup, you could be doing writing on it. So we have to use some strategy to block files, such as a dump (which will lock the tables when to dump the database) or a snapshot.

Choose your domain provider.

(versión en español)

In another article we describe what a domain is and some concepts related to it. In this article we will describe some things to consider when registering a domain.

Types of domains.

The extent of each domain (which is on the right after the point) is what is called top-level domain (TLD).

There are two types of TLDs:
The generic (gTLD) such as. com,. org, .net …
And the country code (ccTLD) like .es, .uk, .It …

What we know as the domain as such would be a second-level domain, for example mydomain.com.  A third level domain could be mydomain.com.uk which are usually cheaper.

How to register a domain.

(versión en español)
What is a domain?
A domain or domain name is an identifier that groups a number of devices or services connected to the Internet.
Another possible less technical definition, would be the name that gives presence (usually a company) on the Internet.
A domain is always associated with the IP address of a device connected to the Internet, as it could be a web server. This makes it easier to connect with one of these devices, since it is easier to remember a name like midominio.com an ip address.
