Using mmbackup

When mmbackup is run on a file system that has AFM filesets, only the cached data from the filesets is backed up.

The mmbackup does not back up the uncached data from the AFM filesets.

In a file system that is HSM managed, a backup operation in either the cache or home fileset will skip over migrated offline files that were not yet backed up. The backup of a file that is evicted from a cache causes the file to be read again from home to cache. To avoid reading the file again when eviction on the cache site is enabled, ensure that the backup occurs before the eviction.
