Backup and Recovery

Email  |  Phones  |   Dal sites & file storage

Backup, and sometimes recovery, is an important part of information security.  The steps necessary to accomplish either of these tasks – and even the need to make a backup – will vary based on the service or device. Only a couple are covered below so ask your local IT Support staff or the Help Desk if you have further questions.



Dalhousie is using Office 365.  Microsoft automatically replicates that email for us. They keep multiple copies across multiple data centres.

Although it raises other issues and is probably unnecessary, you may wish to consider making a local backup by:


When you delete items in Office 365, they are moved to the Deleted Items folder. You can either let things stay there, or you can set Outlook to automatically empty your Deleted Items folder when you sign out.

With today's large capacity many are choosing to never empty Deleted Items.  This makes recovery trivial — see instructions for Outlook 2010, Outlook 2013 or Outlook Web App.

However, even after emptying Deleted Items recovery is possible:

  • By you for up to 30 days (same recovery instructions as above)
  • By the email administrator for up to an additional 14 days (email


Phones are easily lost, stolen or destroyed. In the first two scenarios the risk of information disclosure likely outweighs the risk of information loss.  So employees need to first ensure they have followed the security standards.


Smartphones are highly personal devices.  So if you are using Office Mobile, OneDrive, Office 365 email or other server-based services, which are automatically backed up, then your remaining backup concern will probaby be: pictures, contacts, and credentials (such as remembered connections to social media).

Cabled backups

Many vendors now provide software you can use to backup your smartphones via USB cable.  Kies for Samsung phones is one example of free software but there are others.  Commercial software is also available and can offer additional features.

Wireless backups

Few are dilligent enough to routinely connect a cable and backup their smartphone. So for most, wireless (AKA Over-The-Air or OTA) backups are the way to go.  Go to each phone maker's website to find out how to do this.


Recovery methods will vary from software vendor to service provider.

Dalhousie websites and network file storage

The following services are hosted in the Dalhousie Data Centres:

while My.Dal is hosted with Microsoft.


All these server-based services are backed up automatically and in multiple locations.


In most cases deleted files can be recovered by you but others require an administrator. If in doubt about how to restore your files contact
