The primary backups of network drives are made on weekdays automatically, using volume shadow copy technology. Volume shadow copy is a Windows integrated backup technology that allows users to retrieve deleted files using the Volume Shadow Copy feature while logged in on a Metropolia workstation.

External backups are made to ensure longterm data retention. They works as a good additional safety measure when added security is needed in data storage and when data recovery from a earlier time long in the past must be possible.
All the above listed network drives (excluding scratch) and home drives are backed up daily also in the Powerprotect system and these backups are stored for 3 months.
Data restore from Powerprotect is done by System Maintenance. A restore request can be sent to Helpdesk. However, the above mentioned restore from a shadow copy should be tried first, before making a service request.
Deleted emails are moved to the Deleted Items folder, and they stay there until the folder is emptied. Items removed from the Deleted Items folder are moved to dumpster (Recoverable Items folder) from where the user can still recover them during 90 days.
Users can backup their e-mail and use the backup e.g. at the end of studies or employment and transfer the backup to their home computer.
