I really need a NTP Time Server?

NTP time servers are simple devices, meaning they are used for purposes of time synchronization, receiving an external source of time which is then distributed over a computer network using NTP (Network Time Protocol).

However, with a large number of 'free' Internet servers on the network many administrators make the decision that the NTP time server is not necessary for the parts of the equipment and that their network can dono. However, there are many pitfalls of relying on the Internet as a time reference, Microsoft and the United States Physics Laboratory of NIST (National Institute of Standards and Time) Recommend external NTP time servers instead of ISP.

Here's what Microsoft says:

"We strongly advise you to the source to configure the authoritative time server to gather the hardware of the time. When you configure the authoritative time serversynchronize with an Internet time source, there is no authentication. "

Authentication is a security measure implemented by the NTP to ensure that time is the signal from which claims to be. In other words, authentication is the first line of defense in protecting against malicious users. There are other security issues with the use of the Internet as long as the source of all communication with an Internet time source is the TCP / IP ports must be leftThis firewall can also be manipulated by fraudsters.

NIST recognize the importance of the NTP time server systems for the prevention and detection of security threats in their guide to computer security log management, suggest:

"Companies need to use technology to synchronize the time, as the Network Time Protocol (NTP) server where you can keep 'watches log sources in line with the other."

Introduction to Tape Backup

If you are a small company, chances are you're saving important files on a server. But what happens when a disaster? How did you ensure that the files will not be lost? Many people do not realize that the loss of files could cripple their business. You can insure your office and equipment, but you can not insure files. You can not repair or buy back lost files. Ipso facto, they are lost!

This brings us to the concept of disaster. What is disaster recovery? Ifwe think of disaster recovery is frantically trying to retrieve data that has already been lost, then you're behind the 8-ball! The disaster recovery is to safeguard the data of your organization so that it can be easily restored in case of crippling disasters. And with a standard file backup strategy is undoubtedly the most important part of disaster recovery.

What you should do is make sure that all files on a backup server to anotherstorage medium - tape, removable hard disk, NAS device, and so on. Most companies choose to use tape. Let's see how to set up a tape backup strategy for your business.

1. Tape - the perfect backup medium

Not the tape an anachronism in the age of optical disks, removable hard drives and a plethora of magician-bang, random-access storage media? The tape is really a dinosaur in relative terms, but it's ideal for backup. The tape is slow, but allows a lot of data ... a mid-rangeshould be sufficient for the entire backup. Plus server tape, the tape is extremely cheap - mid-range tapes cost around $ 20 each.

2. When you need a backup?

Typically, the backup tape made at the end of each day. Right in the tape and let the backup process run overnight. If the server is ever hit by a catastrophic disaster, at least you have saved all the previous day.

3. Tape Rotation

The ideal solution would with a tape backupnew tape for each backup. This means that the purchase of a new tape for every day activities of your business. This is not profitable for the company. The tape is cheap but not cheap!

For this reason we are talking about tape rotation. Tape rotation means to reuse tapes of previous backups. The simplest tape rotation scheme is one tape for each day of the week. The tapes are labeled Monday, Tuesday, Wednesday, Thursday and Friday.

You can restore data from a tapein the library, or in this case, every day the past week. This strategy requires only five tapes, but only provides a history of backup week.

4. Grandfather-Father-Son - A Case Study

The grandfather-father-son schedule is the most common method, and is going to back up your data as follows:

* Every day - the 'son tapes "

* Every week - the 'father tapes "

* Monthly - the 'grandfather tapes "

This system is more powerful thanfive tape rotation, but requires more tapes.

This strategy allows you to retrieve data from the last week, plus any Monday over recent months, plus one month for as many monthly tapes as you have. Variations on this system are available, and offer a trade-off between the number of tapes required, and the number of monthly records available.

5. Different types of backup

Different types of backups available in backup software.

* Full - all filesdata system

* Differential - all files are added or changed since last full backup

* Incremental - all files added or changed since the last full, differential or incremental

* Daily - all the files added or changed on the day of the backup

A full backup copies all files and system data to backup media. It represents the sum of all recovered data from a single tape.

Differential, partial and incremental daily backups are designed to reduceamount of data made to the media, speeding up. Retrieve data using one of these backups, the last full backup tape is also required, along with any other partial backups since the last full backup.

6. Tape backup software

At this point you may think that performing tape backup is a complex task. tape rotation, incremental backups ... Sure, you can try to do it manually, but this could be the backup process hiddeously challenging and prone to humanError! The solution is to invest in a good piece of server software to manage backup and schedule backups to tape for you.

What should you look for in a tape backup software? For many small business owners, the price is crucial. Many brands of backup software is too expensive - $ 1,000 + range - and contain features that you'll ever need. Look for a backup program that is specifically designed for small businesses instead. It should be easy to use, reliable andat affordable prices. Choose a good tape backup software and you're on your way to the security of your files and data.
