 ====== Backup of Laptops ======
-Laptops are the nightmare of any system-manager. Not only they are always a special case, therefore taking the same amount of work as 50 identical workstations, but also (and more importantly), their backup is under the only responsability of the user.
-The files on a laptop are much more in danger than those on a workstation or on a file server: the laptop HardDisk is smaller and more fragile, the laptop can get stolen or lost, laptops get into many different uncontrolled networks....
-Nevertheless, we know that very few users backup their data on a regular basis.
-As Laptops become more and more convinient to use, the important work data also becomes more and more in danger. It is useless to have a sophisticated centralized backup system as the one described above if users keep their important data on their laptop. So **please backup your work data as often as possible**. Afterall, your work data belongs to EPFL.
-===== Laptop managed by Lab Administrators ====
+===== EPFL Backup System for Laptop ====
-The portable computers (linux, windows, OsX) managed by your sys admins are
+** All Employee of EPFL are required to do regular backups of the laptop computer they use **\\
-configured to use one of our server to backup the whole content once they are
+For this reason EPFL provide a backup service (Druva InSync) free of charge that every user can request to use.
-connected to the local network by wire.
+to get your Druva InSync account, please contact your system administrator, then, once installed and configured, the program will backup your files every 4 hours even if you're not connected to EPFL networks.
-It's reccomended to leave the computer connected to the network at least one
-hour per week so the systems have the time to do the backup sync
-correctly and completely (an interrupted backup procedure is quite useless).
-For performance/security reasons the backup via wireless cannot be used.
 ===== Personal Laptops =====
-The lab doesn't provide direct support to personal laptops, but you can use different services of our filer structure to your gain. The use of these services as backup system is under your only responsability, we don't control what you do and how you do it.

-  - Homedir: the home directory is to store your work related documents/programs/stuff, but you can use it also to store some personal related data (protos/images, videos, documents) if the footprint is relatively small (under 100 GB).

-  - Scratch server: The scratch server provide space for everyone and there's no limit on the use of it. plesae use it as you like, but adopt a fair play policy, as everyone in the lab will need to store data.

-  - Cloud (Test): we currently provide access to one of our file servers via a cloud client (it means that it will be accessible always, even if your computer is connected to another iand far away network). The address to use is [[http://rain.epfl.ch/owncloud|Rain Cloud]]
+  - google disk/dropbox/microsoft onedrive: these and others internet services are offering storage space for your personal data, **but their storage/use policy is against the rules of EPFL, the European GDPR and/or the Swiss laws regarding privacy** . Please refer to official EPFL documentation/policies about the  use of cloud services.
-  - google/dropbox/microsoft: these and others internet services are offering storage space for your personal data, but we do not reccomend using them as the access policy to these stored information is not secure. Also the bandwidth necessary for using these services is quite important, nowadays.
 ===== Syncronizing work stuff with Unison =====
 [[http://www.cis.upenn.edu/~bcpierce/unison/|Unison]] is a very fast, efficient and easy to use file-synchronization tool for Unix (Linux and Apple OsX) and Windows.
-Note that, although very convenient, **Unison is not a real backup tool**: it does not keep an history of files, and it tends to replicate mistakes instead of repearing them (a file deleted by mistake on one machine will be deleted also on the other machine). On the other hand, we keep various backup of your home directory on the server. Therefore keeping your laptop in sync with your directory on our file-server is almost like backing it up.

 Here we show how it can be used to keep the work stuff on your laptop in sync with your home directory on the file server.

 ==== Install Unison ====
-You can either download it directly from the [[http://www.cis.upenn.edu/~bcpierce/unison/download.html|official web site]], or use a precanned package from your favorite distribution. Unison is included in most linux distribution and on both [[http://fink.sf.net|fink]] and [[http://macports.org|mac ports]] for Apple OS X. For a nice feedback from the backup scripts, we also suggest to install the [[http://growl.info/|growl notifier]] on OS X and libnotify on Linux.
