Short answer
It depends on what you are restoring. With FirstNet Microsoft 365 Backup, a single email or file typically takes minutes, a full user's mailbox and OneDrive typically takes hours, and a full SharePoint site or Teams content can take hours to one or two days.
In detail
Typical restore bands:
- Single email or OneDrive file: minutes, driven by search time and Microsoft's responsiveness
- Full user (mailbox and OneDrive): hours, driven by data size and Microsoft throttling
- Full SharePoint site or Teams content: hours to one or two days, driven by site size, item and version count, and SharePoint throttling
- Bulk event across many users: days, managed through a prioritised runbook
These are typical ranges, not SLAs. Actual times depend on tenant size, item size, Microsoft throttling and connectivity, and on whether you restore to the original or an alternate location.
If restore time is a hard requirement, FirstNet confirms it with a short proof of concept before you commit. For bulk events such as a ransomware incident, planning the restore order in advance makes the biggest difference, which is where the optional Managed Backup Service and regular restore testing help.
