Troubleshooting


Problem

Limitations and known issues related to email backup are documented below for Continuous Data Protection for Files v6.3.x and FastBack for Workstations v6.3.x, v7.1.x If you're upgrading, please review the most recent Readme Document for fixes since the CDP for Files 3.1 release for CDP and the FastBack for Workstations most recent Readme document for fixes since the 6.1 release.

Resolving The Problem

Tivoli Continuous Data Protection for Files (CDP) version 6.3 and FastBack for Workstations (FB4W) version 6.3, 7.1 includes improved support for backing up Email applications but there are some limitations and known issues.

Email Backup Limitations and Known Issues
Tivoli Continuous Data Protection for Files and TSM FastBack for Workstations does not purge email files to make room for other backups.

Email backups are not constrained by the remote storage limit, but may purge older non-email backups to make room for the e-mail files.

Users should set the remote pool size to account for the number and size of the email files they expect to back up plus space required to backup all non-email type files.

When using Mozilla Thunderbird *.bitmap.msf needs to be added to the exclude list.

Email data-level changes are not supported when using Microsoft Internet Information Server's (IIS) WebDAV feature and Tivoli Storage Manager servers.
The data-level change feature of email backup does not work when backing up to WebDAV IIS and Tivoli Storage Manager servers. Email backups will be completed successfully to these servers, but the complete files will be backed up each time, rather than using delta files for subsequent changes.

Known Issues when doing Email backup
Under some conditions, the entire email file is backed up instead of just the changes since the last backup. These conditions occur when:
1. A network connection interruption is experienced while a delta file is being backed up.
2. The file size of the database grows since the last backup.
3. The database is changed while CDP/FB4W is not running and tracking changes.

Lotus Notes Limitations and Known Issues
The Lotus Notes backup improvements work specifically with Notes Version 7.0.2 and above; earlier versions do not fully exploit the features. For example, on versions of Lotus Notes lower than 7.0.2, backup performance will be slightly effected due to a re-try when there are changes to the database during a backup. Also a backup of the full database file will happen more frequently with a decrease in the frequency of delta backups.

Lotus Notes enhancements are supported on Windows Vista
The new Lotus API enhancements are supported on systems running Windows Vista.

Please consult the Lotus Notes support site to make sure that you run a version of Lotus Notes that is compatible with the version of Windows Vista you are running.

Known Issues when entering Lotus Notes password.
The password pop up prompt can come up two times. The second window can be ignored and closed.

If the user enters the password incorrectly two times (i.e., in both of the password prompt windows), there will not be an error message, but the Lotus Notes databases will not be backed up. The next time the application tries to back up Lotus Notes databases, the password prompt will display again.
