About Working With Microsoft Exchange Server - HP BB118BV - StorageWorks Data Protector Express Package User's Manual & Technical Reference

TIP:
You can use this feature to ensure that the databases are always backed up in full mode, but that other
objects are only backed up when changed. This guarantees the greatest security for the most crucial files
(that is, the Exchange Server databases), while not making jobs unnecessarily large by not backing up
the entire network (that is, by backing up only the changed files).
Full When the Backup mode of a job is set to Full, Data Protector Express checks this setting to see how
the job should be run with Microsoft Exchange Server databases. Full is the only possible setting, so the
databases will be backed up in this mode. In this case, both the database files and the transaction logs
are backed up.
Differential When the Backup mode of a job is set to Differential, Data Protector Express checks this
setting to see how the job should be run with Exchange databases. By default, Data Protector Express
runs the job as an incremental job and so only the transaction logs are backed up.
If you want jobs with a Differential backup mode to back up both the database files and the transaction
logs, change this setting to Full. In this case, Data Protector Express will treat the Exchange Server
databases as if it were running a job in Full backup mode.
Incremental When the Backup mode of a job is set to Incremental, Data Protector Express checks this
setting to see how the job should be run with Exchange databases. By default, Data Protector Express
runs the job as an incremental job and so only the transaction logs are backed up.
If you want jobs with an Incremental backup mode to back up both the database files and the transaction
logs, change this setting to Full . In this case, Data Protector Express will treat the Exchange Server
databases as if it were running a job in Full backup mode.

About Working with Microsoft Exchange Server

When you use Data Protector Express to back up and restore Microsoft Exchange Server databases, you
must pay special attention to the role Windows NT security serves in Microsoft Exchange and the backup
mode of the Data Protector Express backup jobs.
Microsoft Exchange and Windows NT Microsoft Exchange uses Windows NT security information
for authentication and thus when planning a comprehensive backup program, you must consider the
Windows NT operating system as well. Be certain to include backup and restoration of the Windows NT
operating system as part of your Microsoft Exchange disaster recovery plan.
Backup modes You can use the Options tab of a job to set the Backup mode for any type of backup
jobs: full, incremental, differential or copy. For scheduled automatic rotation jobs, Data Protector Express
automatically updates this job setting to the value indicated on the Schedule tab of the job.
For more information, see Options and Scheduling for Backup Jobs.
When the Backup mode is set to Full, all files selected are backed up, including the entire information
store and directory databases. Transaction logs are also backed up and then purged.
When the Backup mode is set to Incremental, only changes that have occurred since the last backup job
are backed up. In particular, for databases, only the .log files are included in the backup job.
CAUTION:
These .log files are then purged.
When the Backup mode is set to Differential, for databases, only the .log files are included in the
backup job, but these files are not purged.
When the Backup mode is set to Copy, Data Protector Express runs the job in Full backup mode.
