After some building, I realized that a backup is a snapshot of a resource, not the whole m365 service. Initially, I assumed that 1 backup takes the whole service per tenant (https://discord.com/channels/1022200980487557130/1022200981376745474/1231385151376719892). This doc update should help clear the confusion more. Maybe there is a better way to word it, so any other suggestions are welcome. --- #### Does this PR need a docs update or release note? - [x] ✅ Yes, it's included - [ ] 🕐 Yes, but in a later PR - [ ] ⛔ No #### Type of change - [ ] 🌻 Feature - [ ] 🐛 Bugfix - [x] 🗺️ Documentation - [ ] 🤖 Supportability/Tests - [ ] 💻 CI/Deployment - [ ] 🧹 Tech Debt/Cleanup #### Test Plan - [ ] 💪 Manual - [x] ⚡ Unit test - [ ] 💚 E2E --------- Co-authored-by: ashmrtn <3891298+ashmrtn@users.noreply.github.com>

# Concepts
|
|
|
|
Before using Corso, it's important to familiarize yourself with some key concepts.
|
|
|
|
## Microsoft 365 concepts {#m365-concepts}
|
|
|
|
* **M365 Tenant** is typically associated with a unique domain (for example, `contoso.com`) and represents a dedicated
|
|
and logically segregated instance of the Microsoft 365 services plus associated data available to your organization.
|
|
|
|
* **M365 Service** refer to a cloud-applications available through the Microsoft 365 platform. Corso supports
|
|
backup and recovery for Exchange Online, OneDrive, SharePoint, and Teams.
|
|
|
|
* **Azure AD Application** represents an Azure AD digital identity/service principal and associated configuration which
|
|
define the accessible resources and permitted actions on these resources through the application. Corso uses an Azure AD
|
|
application to connect to your *M365 tenant* and transfer data during backup and restore operations.
|
|
|
|
## Corso concepts {#corso-concepts}
|
|
|
|
* **Repository** refers to the storage location where Corso securely and efficiently stores encrypted *backups* of your
|
|
*M365 Service*'s data. See [Repositories](../repos) for more information.
|
|
|
|
* **Backup** is a copy of a resource of your *M365 Service*'s data to be used for restores in case of deletion, loss,
|
|
or corruption of the original data. Corso performs backups incrementally, and each backup only captures data that has
|
|
changed between backup iterations.
