performance penalty if archiving on a file system that has a large number of changes

to many subdirectories. When the scanlist is consolidated, these directories are

combined upwards to a common parent, which results in a deep recursive scan over

many subdirectories.

The setarchdone Directive: Controlling the Setting of the

archdone Flag

The setarchdone parameter is a global directive that controls the setting of the

archdone flag when the file is examined by sam-arfind.

This directive has the following format:

When all archive copies for a file have been made, the archdone flag is set for that

file to indicate that no further archive action is required. During an inodes scan, the

archiver detects whether the archdone flag is set, and if it is set the archiver does

not look up the path name for the inode.

During directory scans, the archiver also sets the archdone flag for files that will

never be archived. This can be a time-consuming operation and can impact

performance when large directories are scanned. The setarchdone directive gives

you control over this activity. The default setting for the directive is off if the

examine directive is set to scandirs or noscan.

This directive controls the setting of the archdone flag only on files that will never

be archived. It does not affect the setting of the archdone flag after archive copies

are made.

The wait Directive: Delaying Archiver Startup

The wait directive causes the archiver to wait for a start signal from samu(1M) or

File System Manager. By default, the archiver begins archiving when started by

sam-fsd(1M).

This directive has the following format:

The wait directive can also be set for an individual file system.
