This section describes the process for creating a schedule to back up Exchange information stores only.
1 On the backup system, create calendars for the Exchange information store backups. These pre-defined calendars are available:
• Exchange Weekly Master Calendar – Exchange Master backup on Saturday at midnight
• Exchange Daily Differential Calendar – Exchange Differential backup run daily Sunday through Friday at midnight
• Exchange Daily Master Calendar – Exchange Master backup run daily at midnight
• Exchange Hourly Differential Calendar – Exchange Differential backup run hourly between 6 am and midnight.
Unitrends recommend that the Exchange Weekly Master Calendar and Exchange Daily Differential Calendar be used for an Exchange InfoStore Recovery (EIR) strategy.
When Exchange Quantum Recovery (EQR) strategy is used, Unitrends recommends the Exchange Daily Master Calendar and the Exchange Hourly Differential Calendar to provide more granularity in item level recovery. This allows for more restore points and better efficiency when performing an item level restore.
Custom calendars may also be used. We recommend copying the pre-defined calendar and altering the copy as desired.
Note: Calendars have built in fault tolerance. Exchange information store masters backups override Exchange information store differential backups. Exchange information store differential backups are prevented from overlapping. If an override is performed, the following message displays in the backup output:
Another backup of higher priority has been started or is currently running. This backup has been cancelled.
2 Create two selective schedules as described in To create an Enterprise backup schedule.
One schedule will be for the Exchange master backup and the other for the Exchange differential backup. The Exchange master backup schedule will use the Exchange Weekly Master calendar, the Exchange Daily Master calendar, or a custom calendar you created. The Exchange differential backup schedule will use the Exchange Daily Differential calendar, the Exchange Hourly Differential calendar, or the custom calendar you created.
We recommend using two separate selective schedules, but a single schedule using the split list option is acceptable also. The split lists option will allow you to use a unique options list for the master and differential backups within the same schedule.
3 Create and apply a unique inclusion selection list for your Microsoft Exchange server to each Exchange schedule. See To create a selection list and To apply a selection list or option to one client for details.
We recommend using the file C:/PCBP/Exchange.dir/BPExchange.ini as your selected file. This will allow for minimal file data to be backed up in this schedule.
4 Apply backup options to each schedule. See To apply a selection list or option to one client for details.
Two pre-defined options are provided for your Exchange information store backups. The Exchange Master Option will be for your master Exchange backup and the Exchange Differential Option will be used for your differential backup. Each option list is configured with pre-backup commands to launch the information store backup on the Exchange server. A custom option may also be used. We recommend copying the pre-defined options and altering the copy as desired.
As provided in the pre-defined options, Exchange information store backups require pre-backup commands.
The master backup will use c:/pcbp/Exchange.dir/ExchMaster.bat as a pre-backup command.
The options list for your differential backup will use c:/pcbp/Exchange.dir/ExchDiffer.bat as a pre-backup command.
This completes the process for creating Exchange information store schedules.
