 > Once a volume has exceeded a `maxfiles` limit, you cannot reduce volume size below the quota corresponding to that `maxfiles` limit even if you have reduced the actual used file count.

+You cannot set `maxfiles` limits for data protection volumes via a quota request.  Azure NetApp Files automatically increases the `maxfiles` limit of a data protection volume to accommodate the number of files replicated to the volume.  When a failover happens to a data protection volume, the `maxfiles` limit remains the last value before the failover.  In this situation, you can submit a `maxfiles` [quota request](#request-limit-increase) for the volume.
