DUMPSIZE — User Commands

NAME

dumpsize − Calculate size of dumps on a tape

SYNOPSIS

dumpsize tapeNum datesFile

OPTIONS

tapeNumThe number of the tape in question.

datesFileThe path of the dumpdates file.

DESCRIPTION

This script grovels over the dumpdates file and calculates how much space on the tape is taken by the dumps, file marks, etc. The tape number is the first argument. (Each dump tape has a number, which is written on the tape and its case.) The second argument is the path of the dumpdates file, usually /sprite/admin/dump/dumpdates.

The output from the script gives how much space is taken for each day’s dumps (including a guess at how much is needed for file marks) and the total space taken on the tape. This lets you guess how much space will be needed for another day’s dumps and whether it will fit on the given tape. (Allow 2 gigabytes for an Exabyte cassette.)
