There are two main reasons why your connector can experience poor backup or restore performance:
- The connector is being throttled by Microsoft
- Keepit is processing a large number of small files
If Keepit detects that a connector has been experiencing poor performance for more than 24 hours, your connector's health with be changed to unhealthy. To discover the specific reason that is causing poor performance, click on the warning message on your connector. From here you can access more information and a how-to guide on how to calculate the estimated time for a job to complete.
You will also receive an email and an in-app notification about the health change, which will list the specific reason.
The connector is throttled by Microsoft
To ensure all customers receive good service, Microsoft offers only a limited amount of bandwidth to each of their Office 365 or OneDrive customers. If limits are exceeded, it can impact performance speeds in Keepit.

Keepit is processing a large number of small files
The number of files and their sizes in your tenant impact the job performance. The more small items that are present, the longer the backup job can take because Keepit needs to process each file separately. In this case, the backup speed may seem to be slower than expected, even though the number of files secured will be increasing quickly.
