Backup Tasks:

Data Fetching Tasks: Limits data fetching speed before VM recovery is completed to ensure VM performance.

Backup Deletion Tasks:

1. Limits the read and write speed for a single VM backup deletion task.
2. If the upper limit is too high or not configured, backup deletion tasks can consume too many IO bandwidth resources, thus triggering storage IO usage alerts, especially when the storage performance is poor.

Backup Health Check Speed:

1. Limits the read speed for a single VM backup health check task.
2. If the upper limit is too high, health check tasks can consume too many IO bandwidth resources, thus triggering storage IO usage alerts, especially when the storage performance is poor.
