CreateMigrationPolicies
Migration policies initiate movement of file data from disk to
tape.
The following types of policy can be run:
• Store data to tape (based on DataClass parameters).
• Remove data from disk (based on disk space)
The fspolicy -s command is used to invoke the policy to
store data to tape. Eligibility for storage is basedon the
DataClass parameters of class.
The fspolicy -t command is used to invoke the policy to
truncatedatafromdiskafterithasbeenstoredtotape.
Eligibility for truncation is per file system filesystem and based
on the file attributes, such as last access date.
Tip
ADIC recommends that migration policies be app lied on a
routine basis. Periodic application of migration policies is best
accomplished through the use of a crontab, to invoke many
routinely executed UNIX commands.
