Technical Changes for Version 3 Release 7--September 1999

The following changes have been made for this edition:

Creation of portable backup sets for clients
The server can create portable backup sets for clients that are at the latest level of Tivoli Storage Manager. The function consolidates a client's active backup files onto portable media that may be directly readable by the client's system for restore operations. See Generating Client Backup Sets on the Server.

Logical volume backup for clients
Backup-archive clients can now back up logical volumes to the Tivoli Storage Manager server. See Policy for Logical Volume Backups for suggestions on policy for such backups.

Performance enhancements
Performance enhancements include the following:

Automatic tuning of selected server options
Selected server options can be tuned automatically by the server. See Automatic Tuning of Server Options for a list of options.

Database page shadowing
Database page shadowing mirrors every write to a database page so that the server can recover pages that have been partially written to should an outage occur that affects both mirrored volumes. Combined with the MIRRORREAD and MIRRORWRITE server options for the database and recovery log, you can specify your preferred level of protection, recoverability and performance. See Specifying Mirroring and Database Page Shadowing Server Options.

Database snapshot
You now have the choice a making a database snapshot, which is a full database backup to media that can be taken off-site. The database snapshot does not interrupt any database backup series and cannot have incremental database backups associated with it. See Doing Snapshot Database Backups.

Device support
Enhancements to device support include:

See Chapter 4, Using Removable Media Devices with Tivoli Storage Manager and Chapter 6, Defining Drives and Libraries.

Proxy Web services
See Quick Start for details.

Password expiration controls
You can reset the password expiration period for all or selected users. See Setting User Password Expiration.

Licensing changes
Some features that formerly required the purchase of licenses are now part of the base Tivoli Storage Manager product. See Licensed Features.
