Where can I get synchronization services

synchronization

The term synchronization is ambiguous and is used in different areas. Literally, synchronization means "time together" (Greek syn = together and chronos = time). In the case of digital media, synchronization means that data is brought up to date on different end devices. For example, accounts and bookmarks can be synchronized. Data synchronization is a synonym for synchronization.

Background [edit]

The days in which users only used the desktop to write emails, create calendar entries or write texts are long gone. Today we use notebooks, smartphones, tablets and desktop PCs to manage and create our digital data. With the use of several different devices, it has become more and more difficult to keep all data on the same level.

Example [edit]

A user starts the day by checking his appointments at home and storing them in his Outlook program. Then he starts the day, takes the smartphone with him and goes to the office. In the meantime he got a call. He has saved the new number. In the office he writes an email that he couldn't finish because he has to go to a new appointment. There he has his tablet with him. This chain could be continued indefinitely and already shows what task synchronization can fulfill.

Due to the multi-device use and especially the increasing use of mobile devices, the synchronization of data has become a daily part of everyday business, but also in the private sector.

How it works [edit]

Data can only be synchronized if the data can be accessed from a central point. The storage medium for this is usually a server. A popular example of data synchronization is e.g. the cloud. This is an online memory that can be accessed from any internet-enabled device with the appropriate access data.

The user loads their data actively or automatically onto the server in order to then either automatically or manually download them to a mobile device or another device. Alternatively, the data can always remain on the server. The user then needs a utility program such as a browser to be able to access this data.

Synchronizable data [edit]

In principle, all data can be synchronized with different end devices. The prerequisite for this is that they are temporarily stored on a server from where they can be picked up again.

Examples of data that can be synchronized:

  • Calendar entries
  • Mails
  • contact details
  • Documents
  • Storage space
  • Browser window
  • bookmark

Synchronization of mail accounts and user profiles [edit]

If mail accounts are used on different end devices, e.g. on the desktop and the smartphone, this data must be synchronized so that the user can use the same database on all devices. In this case, the SMTP protocol is used, which ensures that sent and received emails always remain on the mail server. The user can then access it from any device with his login data.

This happens in a similar way with user profiles such as XING or Facebook. While emails can be backed up directly to local storage, this is not the case with social networks. There the data always remains with the operator, who gives the user access to his data via login.

Synchronizing browsers or e-book readers [edit]

Some browsers such as Google Chrome allow the user to synchronize tabs or bookmarks. The prerequisite for this is that the user has logged in with their Google account and activated synchronization. The same applies to devices such as Amazon's Kindle or devices from Apple. Anyone who, as a registered user, reads a book with a Kindle or an iPad, for example, can continue reading at exactly the same point on another mobile device as soon as they have logged in.

Data protection [edit]

When it comes to synchronization, there are always concerns about data protection. On the one hand, the data is rarely with the user himself, but on servers in the USA and other countries. An example of criticisms of data protection is the recurring debate about images on Facebook[1] or user profiles on Google.[2] On the other hand, during the synchronization process there is often the possibility that attackers could gain access to sensitive and personal data through poorly secured networks. Accordingly, users of synchronization services should, on the one hand, pay attention to where their data is being backed up and, on the other hand, how they can best secure their personal data themselves.
