FULL vs COPY backups for DP Exchange and include processing

Question & Answer


Question

This document describes the differences between Full and Copy Exchange backups using Data Protection for Exchange.

Answer

The main differences between a FULL and COPY backup is in regards to how the logs are managed for these backups.

FULL:


A full backup backs up the specified storage group, as well as associated transaction logs. The Exchange Server deletes the committed log files after the storage group and logs are successfully checked for integrity and backed up. The log files are not deleted if any storage groups are not mounted.

COPY:
A copy backup is similar to a full backup except that transaction log files are not deleted after the backup. A copy backup is used to make a full backup of the Exchange Server storage group without disrupting any backup procedures that use incremental or differential backups.

The backups taken with Full and Copy can bind to different management classes as they are treated as totally separate backups. The following include statements can be used in the options file.
Examples:

INCLUDE "SERVER1\...\full" FULL_CLASS
INCLUDE "SERVER1\...\copy" COPY_CLASS
INCLUDE "SERVER1\...\incr" INCR_CLASS *for backing up the logs

The Copy and Log Backups get inactivated when the next Full backup is performed. It is assumed that the older Copy Backups are obsolete as a newer Full Backup exists.
