SIT is in charge of the backup of all virtual servers and of physical servers dedicated to institutional activities only. Backup is performed every night.
Files can be restored as follows:
- for a week: the five previous days
- for a month: the five previous Fridays
- for one year: the previous twelve first Fridays of each month
- for five years: the first Friday of the year
The backup of physical servers dedicated to research activities is the responsibility of researchers who have access to them.
No backup is performed on the data residing on Google's servers (mail, contacts, calendars, drive, websites, etc.). The above data are stored until you close your account (unless they are in the Trash or Spam folders, where they are stored for 30 days).
