I'm looking for official documentation regarding Backup schedules and restore options in Office 365.

More precisely:

  • How often is backups made
  • For how long is a backup saved
  • How do you restore?
  • How long does a restore take, is there an SLA for this?

I found this from 2012 that answered some of the questions, but is this still valid?

I've had this discussion with Microsoft Support in June 2014. They told me that backups are performed on all site collections on a daily basis and kept for 14 days. In order to get a restore to happen you need to add a service request from your Office 365 tennant admin center (support link in the left navigation).

Unfortunately they can only restore on site collection basis, which is quite big. If you lose a list or a document library, the only option you have is to restore the entire site collection.

However, there are options to use third party tools to make granular backup and restore if you like. Some of my customers prefer to have this setup to have the extra security since the cloud is the scary-out-of-control-cloud :-)

A week ago your link was referenced by Microsoft Officials on the O365 community, which makes it kind of offical.

  • OK, so we can possibly see it as still valid then! I guess lists and items can be retrieved from the recycle bins (they can be found there up to 30 days, so that is a bit better than the backup then) Oct 23, 2014 at 12:02
  • @RobertLindgren True! The Recycle Bin is every admins friend and protection from hazardous users ;-)

  • Is there any way I can backup a document library in app web, in case someone uninstalls the app mistakenly?
