Manage Windows Updates in Windows 2016

In Windows Server 2016, the administration of the (automatic) Windows Updates has changed slightly. The following tutorial will show you how to check and manage the Windows updates for your Windows Server 2016 system.

1. Please connect to your server using RDP and open the Settings App via the Start menu.

Afterwards you can click on "Update & Security" which will forward you to the following screen.

Everything regarding updates can be done via this screen.

You have the option to "Check for updates", which will check for the latest updates and automatically download and install them. If some updates require a reboot, Windows will schedule it accordingly.  It is possible to set "active hours" from the link "Change active hours" where a time frame can be given in which Windows shall not reboot the device automatically.

It is further possible to set a custom day and time for the reboot via the link "Restart options".

The link "Update history" provides an overview about recent updates where it is possible to uninstall recent updates and to check further recovery options.

The link "Advanced options" provides you with the option to also update other Microsoft products through Windows updates and to "Defer feature updates", which is described by Microsoft as follows:  "When you defer upgrades, new Windows features won't be downloaded or installed for several months. Deferring upgrades doesn't effect security updates. Note that deferring upgrades will prevent you from getting the latest Windows features as soon as they're available".

The link "Privacy settings" will forward you to the general privacy settings of Windows.

Available now: Windows Server 2016

Not long ago, Microsoft officially launched its latest operating system for server systems, Windows Server 2016. We immediately went to work and performed numerous functionality tests and thus ensured a smooth integration in our systems. Today we can finally say:

Windows Server 2016 is available as an upgrade for all our root servers and VPS with 100% SSD!

As you already know from Windows Server 2012, you can once again choose between the Standard Edition and the Datacenter Edition when ordering Windows Server 2016.

If you are a new customer or place an additional order, you can select Windows Server 2016 as your operating system during the order process on our homepage. We kindly ask existing customers to send a short e-mail to our support department, then we will process the upgrade manually.

So what are the costs of Windows Server 2016 at Contabo?

The most important thing first: As a special service for our customers, we offer Windows Server 2016 free of charge for the first two months - for every root server customer. In other words:
No costs apply for the use of Windows Server 2016 on a root server within the first two months.

If you opt for a root server at Contabo, you are free to choose between the two new versions as well as the previous versions of Windows Server 2012 – in addition to a broad selection of Linux distributions. For most of our Dedicated Servers, Windows Server 2016 Standard Edition is available for 39.99€ per month (from the 3rd month onwards, free of charge before). The Datacenter Edition is a bit more expensive with a monthly fee of 279.99€ (from the 3rd month onwards, free of charge before); however, it offers the ambitious user additional possibilities, as for example in the field of virtualization.

If you decide to order one of our VPS with 100% SSD disk space and add Windows Server 2016 as your operating system of choice, you automatically receive the premium Datacenter Edition. It is available from 5.99€ per month for our VPS – the eventual monthly fee depends on the chosen VPS model. Of course, all available Linux distributions can be selected as the operating system for your VPS as well.

Order your new Contabo VPS or root server with Windows Server 2016 today!

Always be up to date with our server status notification!

Some of you have probably clicked on the link “Server Status” on our website contabo.com already and were forwarded to our status website. In the very rare case of irregular issues occurring in one of our data centers, we inform you about it on this website.

Recently we have revised our status site and added more features. By now, we provide information about all scheduled, ongoing and recently completed maintenances of server systems in our datacenter. Not worth mentioning that customers affected by such a maintenance are also informed by us via e-mail prior to this. These maintenances cannot be avoided altogether – after all, some hardware components are subject to attrition and have to be replaced at the appropriate time. Thanks to our transparent status website, you always know about the server systems which are currently being maintained by our technicians.

A click is worthwhile: http://contabo-status.com/

Data loss and how to avoid it

A typical situation: You have been on vacation and have made a lot of great photos which you want to upload to your server in order to share them with your friends and your family. Especially the photo where you were diving with the great white shark. So you uploaded them to your server and after that the photos were deleted from the SD card because you need free space for the next travel. Just working on an update to your website in a hurry, a quick "rm -rf" in the wrong directory and the photo gallery is gone. Annoying!

This is a situation that can occur but the data does not have to be lost. In general, the customer is responsible for a backup and we want to show you how to approach the perfect backup system.

But what is a backup?

With a backup you are creating a copy of your data to be stored on an external storage device. This storage device should be independent of your server, so it could be a hard disk on your local computer, a USB stick or our FTP backup storage.

Different backup types

  1. Full Backup: As the name already indicates the full backup is a complete copy of your data. The advantage here is that all data is complete, but you need a lot of disk space to store your data. If you only perform full backups the available space at your data storage medium will shrink very fast.
  2. Differential Backup: Before performing a differential backup you need a full backup as a differential backup contains only data which has changed or is newly created in comparison to the full backup. Therefore, it is faster but you are also saving data which is already saved in previous differential backups because you save all data that differs from the last full backup.
  3. Incremental Backup: Similar to the differential backup you have to perform a full backup. But instead of always saving all changes that differ from the latest full backup, only the data being changed after the previous incremental backup gets backed up. The only disadvantage is, that if you want to restore that data you need the last full backup and all incremental backups in order to restore to the latest data.

Where to save the backup files

We offer an FTP backup storage, available with various storage space options. If you are interested in this offer, please contact us: support@contabo.com
You can access the backup storage via FTP and FTPS. With support for these protocols it is perfect for file storage. The way to access our backup space is already described here: https://contabo.com/?show=tutorials&tutorial=backup-space.

"I do not need a backup, my server is secured by a RAID system."

CAUTION! A RAID does not replace the creation of backups! A RAID should indeed provide redundancy. If more than one drive fails at the same time or your data is deleted because of an attack from outside or a similar event, a RAID will not help saving the situation. We have read this sentence above numerous times and with our experience we can say, that customers who think that their data is secure because they have a RAID system are very disappointed, if a situation as described occurs. A RAID is very effective to avoid downtime because of a defective HDD and to prevent the need for laborious data restoration.

Nevertheless the mentioned redundancy is not the same as a backup.

"I have an SSD VPS. Because of the snapshot feature I do not have to worry about backups."

Since we have been offering our VPS SSD products with the snapshot feature we have heard this sentence very often. But it is the same as with a RAID. Snapshots are not backups!

What are snapshots good for?

A snapshot freezes the current state of the file system which still points to the same "physical" storage. Snapshots are perfect for "Let's do it and see what happens..." type of situations. If the change does not work you can go back to the state before you have started your work.
So is it a backup? No! Snapshots depend on the VPS and on the host server system the VPS is located on. As already described before, the backup has to be saved to an external location, e.g. our FTP backup storage.

How to create a backup?

All important data has to be saved. Normally you know where this data is located. To store all necessary data an automatic backup routine is the perfect choice.

Using a Linux based OS we recommend to create script which creates a tar.gz file of the data that should be saved and after that, automatically transfers it to the backup storage and also deletes older backups. As this should be done periodically you can use a cron job. If you use a Windows OS you can create a powershell script to do the same steps likewise.

Please note that it does not matter if you use Linux or Windows. You have to know what you are doing as the backup is the only way to restore your data if you are facing an issue with your server.

Of course we always try to support you if you have any questions regarding your backup solution: support@contabo.com.

The last step: Securing your backup

Security of private data gets more and more important. Encryption of the backup files is therefore recommended.

Using a Linux OS you can use tools like gpg to do so. Please find a very good tutorial below:
http://www.cyberciti.biz/tips/linux-how-to-encrypt-and-decrypt-files-with-a-password.html

If you are a windows user we recommend using Veracrypt:

Upgrading Plesk from 12.5 to Onyx

With this short tutorial we will show you how to upgrade your Plesk 12.5 version to Plesk Onyx.

Before proceeding you should perform a backup of all important data. An upgrade always bears the risk of data loss.

On an SSD VPS you will have the ability to create a snapshot, creating a snapshot will give you the possibility to perform easily a rollback to the state "before upgrading".

On any other VPS or dedicated server we recommend downloading all backup files to your local PC or to our FTP backupspace.

After you have saved all important data you will be able to continue upgrading:


Linux:

1. Login via SSH and use sudo -i to start a shell with "root" privileges
2. Type in the following command:

plesk installer

If this command is not working, you can download and execute the installer using the following commands:

wget http://autoinstall.plesk.com/plesk-installer
chmod +x plesk-installer
./plesk-installer


Windows:

1. Login via RDP and open the CMD.exe with Administrator rights (Windows-Key + R)
2. Type in the following command:

"%plesk_bin%"\ai.exe --console


Once you have opened the Plesk Installer you will probably see a warning telling you to backup all your important files.

plesk_windows

After you have agreed you should see something like the image below, there should be displayed your current version of Plesk; if you want to perform the upgrade you will have to select the right version by typing the correct number, in this case number 2.

plesk_upgrade_versionen

After typing in the number of your desired Plesk installation you will accept the download of those new packages. Please note that this step can take up to 30 minutes, it really depends on the Plesk extensions you have installed.

plesk_upgrade

After the upgrade was completed you should verify that everything is working properly.

If you plan to install additional software or change some software you can of course run the Plesk Installer again and select the packages which should be installed.

plesk_software

We kindly ask for your understanding that analyzing problems can be very difficult for us, in case you encounter issues after having added or removed some software through the Plesk Installer. In any case we recommend backing up all your files before making any changes to your Plesk installation.

By the way: Plesk offers tutorials about the upgrade process as well, just click here to access the Plesk University!

There is also the option to start a clean reinstallation of your server with the latest version of Plesk within your customer control panel, in this case creating a backup of your important data prior to the installation is vital, because all data stored on your server will be lost.

Full Monitoring

With the Full Monitoring upgrade Contabo offers a tool to monitor the status as well as the state of services.

Why should I monitor my server?

With a monitoring system you are able to detect offline servers or services immediately. With this tool you are able to minimize a service downtime.

A server administrator is not always online to monitor the server 24/7 (in the night or on vacation). In case of a defect the server administrator needs to be informed immediately.

How does the monitoring system look like?

It does not matter if your server is a VPS or a dedicated server, the construction is the same. The most important information is already described in the first line: Is the server online or offline.

Below you can find the state of the services you have chosen to monitor. You can decide for each service how you want to get informed if the service is down. We support notifications via e-mail and text messages (SMS).

With the menu item "Add Services" we added an easy option to add monitoring for a new service. You only have to choose the protocol type (TCP/UDP) and the port the service is listening to.

VPS

In the picture below you can see a simple monitoring system. We check if the services on port 80 (http) and 443 (https) are running. Additionally, we monitor a custom SSH port on 60500.

monitoring1

Dedicated Server

Similar to the VPS you can check, add and delete the monitored services. The only difference is that you can directly see the data traffic of your server.
