Tools and Utilities for Operations BACKCOPY

BACKCOPY

Use the BACKCOPY utility to create one or two duplicate tapes for archive storage, distribution, or disaster recovery. You can also create one or two labeled (or unlabeled) tape sets from a labeled or unlabeled tape set. The BACKCOPY utility duplicates tapes that are made from a BACKUP utility file-mode operation, but it cannot duplicate tapes that are made from a BACKUP utility volume-mode operation.

BACKUP

Use the BACKUP utility to copy files from disk to magnetic tape.

Disk Compression Program (DCOM)

The Disk Compression Program (DCOM) moves disk-file extents to yield more usable space on a disk. Use the DCOM utility to analyze the current space allocation on a disk, relocate file extents on a disk, and reduce the number of free-space extents. You can also combine free space into larger extents so that files can be allocated with larger extents, which decreases the incidence of file-system error 43 (unable to obtain disk space for file extent).

Disk Space Analysis Program (DSAP)

The Disk Space Analysis Program (DSAP) analyzes how disk space is used on a specified volume. The DSAP utility copies the disk directory and free-space table to the current work file. By specifying options, you can manipulate this data to produce several different reports about the use of the disk space for that volume. The free- space table is limited only by your primary (main) and secondary (contiguous disk space) memory requirements.

EMSDIST

The EMSDIST program is the object program for a printing, forwarding, or consumer distributor, any of which you can start with a TACL RUN command.

Event Management Service Analyzer (EMSA)

Use the Event Management Service Analyzer (EMSA) to extract specific types of event messages from EMS log files and to create an Enscribe database that you can query to analyze problem trends.
