Magnus Box supports Quota restrictions based on different types of data measurements.

All Protected Items Quota 

You can set a limit on the maximum size of all Protected Items in the user's account. When a backup job is performed, the total size of Protected Items is checked against this quota, and the backup job will be aborted if it would exceed quota. If possible, the quota limits are checked before starting the backup, to avoid inconvenient interruptions and wasted bandwidth.

Device Limit 

You can set a limit on the number of devices that may be registered into the user's account. If a user tries to log in to this account using a new device, the registration will fail with an error message.

Storage Vault quota
