AhsayCBSExample for Backup of Large Numbers of Microsoft 365 Users
July 21, 2025
As an example, let us say there are 10,000 Microsoft 365 users needed to be backed up. Since the maximum number of Microsoft 365 users per backup set is 2,000, there are 2 options available. There are further options, but this will involve a large number of backup sets and maintenance of these backup sets will not be practical.
- Option 1: 5 Backup Sets, each has 2,000 Microsoft 365 users
- Option 2: 10 Backup Sets, each has 1,000 Microsoft 365 user
Option 1: 5 Backup Sets, each has 2,000 Microsoft 365 users
| Backup Set Name | User Number |
|---|---|
| Backup Set 1 | No. 1 - 2000 |
| Backup Set 2 | No. 2001 - 4000 |
| Backup Set 3 | No. 4001 - 6000 |
| Backup Set 4 | No. 6001 - 8000 |
| Backup Set 5 | No. 8001 - 10000 |
Option 2: 10 Backup Sets, each has 1,000 Microsoft 365 users
| Backup Set Name | User Number |
|---|---|
| Backup Set 1 | No. 1 - 1000 |
| Backup Set 2 | No. 1001 - 2000 |
| Backup Set 3 | No. 2001 - 3000 |
| Backup Set 4 | No. 3001 - 4000 |
| Backup Set 5 | No. 4001 - 5000 |
| Backup Set 6 | No. 5001 - 6000 |
| Backup Set 7 | No. 6001 - 7000 |
| Backup Set 8 | No. 7001 - 8000 |
| Backup Set 9 | No. 8001 - 9000 |
| Backup Set 10 | No. 9001 - 10000 |
If Option 2 was selected, follow the instructions on how to select the Microsoft 365 users for the last backup set which is Backup Set 10. Doing these steps will ensure that additional Microsoft 365 users will be automatically included in the backup set.
On the backup source, tick the checkbox for the root selection. This will select all the Microsoft 365 users.
Deselect the first 9,000 Microsoft 365 users.
