# Backup of ACLs

Veeam Agent for IBM AIX supports backup and restore of NFSv4 Access Control Lists (ACLs). 

## Considerations and Limitations {#considerations}

- Veeam Agent backs up all supported ACLs automatically.
- Veeam Agent does not support backup of AIXC ACLs.
- You can restore supported ACLs during bare metal recovery or file-level restore. Consider the following about restoring ACLs:

  - During bare metal recovery, Veeam Agent automatically restores all supported ACLs.
  - During file-level restore, you can restore only NFSv4 ACLs.
  - Restoring NFSv4 ACLs requires NFSv4 to be configured on the Veeam Agent machine. For information on enabling NFSv4 in IBM AIX, see [this Veeam KB article](https://veeam.com/kb4713).
  - If you perform file-level restore in the recovery environment, the backup is mounted using the NFSv3 protocol. As a result, restoring ACLs from such backup mount will not be possible.
