Air Cleaner User Manual

Note: This option only applies to backups created on systems running AIX
5.1 or later.
If you perform a backup of an AIX 5.1 system, and then change the file
system type for rootvg to be different than the type originally backed up, it
is highly recommended that you perform a new backup immediately
following the system restore. The reason being that you will no longer be
able to use this existing backup image in order to boot the system solely
for the purpose of importing the rootvg volume group for maintenance.
This is because booting a system that is one file system type from a boot
image that had a different file system type, will cause needed mounts to
fail when attempting to import the root volume group. You will still be
able to use this tape to boot and reinstall the system with the settings of
your choice, simply not to boot and perform maintains on rootvg.
Restore non-sparse files as non-sparse
Specify this option when there data is being restored to an AIX 5.1 system.
You do not have to know which files are sparse vs. non-sparse. This option
usually only applies to certain database users restoring database files.
Previously, only the AIX tar command could restore files as non-sparse.
However, in AIX 5.1 the /usr/sbin/restore command has been modified to
handle this as well.
Note: This option only applies to backups being restored to systems
running AIX 5.1 or later.
