Scheduling Archiving: -startage, -startcount, and

-startsize

As the archiver scans a file system, it identifies files to be archived. Files that are

recognized as candidates for archiving are placed in a list known as an archive

request. At the end of the file system scan, the system schedules the archive request

for archiving. The -startage, -startcount, and -startsize archive set

parameters control the archiving workload and ensure the timely archival of files.

TABLE 3-21 shows the formats for these parameters.

The examine=method directive and the interval=time directives interact with the

-startage, -startcount, and -startsize directives. The -startage,

-startcount, and -startsize directives optimally balance archive timeliness

and archive work done. These values override the examine=method specification, if

any. For more information on the examine directive, see “The examine Directive:

Controlling Archive Scans” on page 55. For more information on the interval

directive, see “The interval Directive: Specifying an Archive Interval” on page 55.

TABLE 3-21 Formats for the -startage, -startcount, and -startsize Directives

Directive Meaning

-startage time The amount of time that can elapse between the first file in a scan

being marked for inclusion in an archive request and the start of

archiving. For time, specify a time in the format used in “Setting the

Archive Age” on page 71. If this variable is not set, the interval

directive is used.

-startcount count The number of files to be included in an archive request. When the

number of files in the archive request reaches the value of count,

archiving begins. By default, count is not set.

-startsize size The minimum total size, in bytes, of all files to be archived in an

archive request. Archiving work is accumulated, and archiving

begins when the total size of the files reaches the value of size.By

default, size is not set.
