When an entire directory or directory tree is restored, and the inactive,
latest, pick,
todate, and fromdateoptions are not specified on the restore command, TSM
keeps
track of which objects have been restored. If the restore process is
interrupted for any
reason, you can restart the restore at the point of interruption by entering
the restart
restore command. It is possible to create more than one restartable restore
session.
Use the query restore command to display a list of your restartable restore
sessions in
the server database. The existence of a restartable restore inhibits further
backups of
that file system until the restartable restore is completed using the
restart restore
command or the restartable restore is dropped using the cancel restore
command.
