Mastering TSM Replace: A Comprehensive Guide to Efficient Data Management

The TSM (Tivoli Storage Manager) replace command is a powerful tool for managing your data backups. This guide delves into the intricacies of replace and provides practical examples to help you master this crucial command.

What is the replace command?

The replace command allows you to replace existing backups with newer versions. This is particularly useful when you've made significant changes to your data and want to ensure you have the most recent backup.

Key Advantages of Using replace:

• Space Optimization: By replacing older versions, you free up valuable storage space.
• Data Integrity: Ensures you have the most up-to-date backup, minimizing potential data loss.
• Simplified Management: Streamlines your backup process, avoiding the need for manual cleanup.

Understanding the Command Syntax:

The general syntax for the replace command is:

tsm replace [options] backup-set-name

Common replace Options:

• -keep: Retains a specified number of backup versions. For example, -keep 2 would preserve the last two versions.
• -oldest: Replaces the oldest version within the specified backup set.
• -newest: Replaces the newest version within the specified backup set.
• -since: Replaces versions older than a specified date.
• -until: Replaces versions newer than a specified date.
• -inc: Replaces incremental backups only.
• -full: Replaces full backups only.

Example Scenarios:

1. Replacing the Oldest Version:

tsm replace -oldest my_database_backup

This command replaces the oldest version of the backup set my_database_backup.

2. Replacing Incremental Backups After a Full Backup:

tsm replace -inc -since 2023-03-15 my_application_backup

This command replaces all incremental backups of my_application_backup taken after March 15th, 2023.

3. Keeping the Last Three Versions:

tsm replace -keep 3 my_webserver_backup

This command replaces all versions except the last three versions of the backup set my_webserver_backup.

Important Notes:

• Always carefully consider the options you use with replace to ensure you are replacing the correct versions and not accidentally deleting important backups.
• Test the command on a test environment before applying it to your production environment.
