Microsoft Backup

Question

Assuming nothing has changes, do you know if Office 365 Groups offers the same retention/restore options as SharePoint online?

Example, Microsoft will make a backup every 12 hours and keep it for 14 days

Group conversations are stored as items in Exchange mailboxes. The mailboxes are protected by Native Data Protection (Exchange Database Availability Groups with 4 copies of each database) like any other Exchange Online mailbox. Unlike SharePoint, Microsoft does not take backups of Exchange Online. If someone deletes something from a group, it will be in the Deletions folder of the mailbox. You can recover the item from there by running a content search and export to PST. Or you might be able to get a copy of the item from one of the members of the group, if they receive updates by email. You cannot use the standard Recover Deleted Items functionality in Outlook or OWA to recover deleted conversations because you do not own the group mailbox.

In April we delivered "soft-delete" which retains a group for 30 days, see this:

Apart of this for Group SPO Site you have the daily backup done by Microsoft

Thank you for your replies, in summaryThe ‘soft’ delete could be used to recover a group that was deleted in error, retained for 30 days. In addition, Microsoft also take a daily backup of a group which is retained for 14 days, in line with SPO?

Please correct me if the SLAs have changed but I believe the daily SPO backup occurs every 12 hours and is held for 14 days. Saying this, there are limitations on the granularity of the backup. Focusing on SharePoint Online there is a&nbsp;lack of ability to restore a single item or list/library - what I find&nbsp;gets deleted most commonly by End Users. Also&nbsp;lacks the ability to remove the items from SharePoint but bring them back at a later time if required controlling sprawl.&nbsp;&nbsp;With Exchange, I believe items can be restored but I believe there was some limitations around Folders.&nbsp;If any of this is a concern of yours Paul, flick me a pm and I can point you in the right direction.
