Backing up and restoring files

When writing to disks or tapes on AIX® with the backup command, SLs are included with the data.

SO authorization is required to use the backup or restore commands to import or export unlabeled data from tapes or disks. When unlabeled data is written, the data is assigned a default SL of SYSTEM_LOW for files and an SL range of SYSTEM_LOW to SYSTEM_HIGH for directories.
