Tivoli Storage Manager for Macintosh Backup-Archive Client Installation and User's Guide

Estimating Backup Processing Time

The first time you perform an incremental backup, Tivoli Storage Manager needs to back up all of your files, which can take a long time. Subsequent backups usually do not take as long. The Estimate function is provided on the Backup and Restore windows to estimate the amount of time it takes to process your files and folders. The estimated transfer is a rough calculation of the time it takes to transfer your data, based on previous transfers of data between your workstation and the current Tivoli Storage Manager server.

The actual transfer time could be longer or shorter than the estimate due to factors like network traffic, system load on your workstation, or system load on the server. The estimate function also does not take into account whether or not files are excluded from backup. The assumption made by the estimation algorithm is that all the files selected will be sent to the server.

Note: During installation, Tivoli Storage Manager creates the TSM GUI Preferences file to record statistics from the backup-archive client estimate function. This file is stored in the following location:
