It depends on how you configure it. We have the 60 day retention setting in OneDrive for retaining files after deletion, and in Exchange we use LitigationHoldDuration set to 60 days as well.


It is not the most ideal way to restore data when you need to, you basically have to do a PST export and let someone sort through what they have mistakenly deleted when they want something back.


On the issue of what happens when Microsoft loses data, this is just one of the things we need to take a chance on. In theory, there are 3-4 copies of all data, you can read their data resiliency paper  and decide if that is good enough. So far we have not had an issue.

Curious.  If you are using litigation hold in this manner for Exchange Online, what are you doing about other O365 services such as OneDrive for Business?  Are you relying solely on the recycle bin for that?

The litigation hold approach is what we do.  With about 50k accounts doing a traditional backup seems daunting.

Subject: [CLOUD] Backup Solution for O365 Mailboxes
 

Good Morning,

 

We have around 1000 student and 300 employees  mailboxes in O365.I was wondering if any institution is using a pure backup solution to back up their O365 mailboxes? We have been told by various vendors that the litigation hold feature in O365 can be leveraged as a backup option, in that case do we still need a backup solution, is it best practice? Is this the way forward with O365?Looking at the cost of pure backup solutions, is anyone going this route?

 

Please advise if any vendor or product that has performed well and is cost effective as a backup solution.

 

Thanks
