What happens in case of an unexpected system shutdown?

An unexpected system shutdown between the express full backups invalidates information

maintained by the Express Backup Driver. At the next backup, Acronis Backup & Recovery 11.5 runs

the data re-sync backup operation by comparing the current database files with the most recent

backup rather than performing a regular full database backup. Although the re-sync increases the

number of I/O requests to the production server, it still saves storage space and network traffic. The

next backups after the "re-synced" backup will proceed as regular express full backups.

What if one of the scheduled backups fails?

If one or more of the scheduled express full backups fail, the next successful backup will be a regular

express full backup based on differences since the previous successful backup.

What happens when maintenance operations involve rebooting of the Exchange

server?

If Exchange server reboot is part of maintenance operations, the next successful backup will be a

regular express full backup.

5.4.1.2 Usage examples

This section provides examples of how you can use the express full backup method.

Example 1. Backing up within a narrow backup window

Case: The company's working schedule allows a backup window of only 5 hours per night. The

network bandwidth is 60 GB per hour. This effectively limits the amount of data that can be backed

up nightly to 300 GB. The Exchange server in the company hosts 500 GB of data making it impossible

to finish a full backup within the required time frame. Daily changes, however, almost never exceed 5

GB.

Solution: Do express full backups to a deduplicating vault. Create a backup plan and schedule the

backup to start at the beginning of the night backup window. To create the initial full backup,

temporarily expand the night backup window. The subsequent express full backups will fit the

backup window.

Steps to perform

1. Connect the console to the machine running Agent for Exchange.

2. Click Create backup plan.

3. Under What to back up, select the required server's data.

4. Under Where to back up, select the managed deduplicating vault.

5. Under How to back up, select the Simple backup scheme.

 In Schedule, select Daily and schedule backup to run at the beginning of the night backup

window.

 Click Show backup type, 2nd location, validation to access the Backup type setting.

 In Backup type, choose Full and select Create full backups using the Express full backup

method.

6. For information about specifying the rest of backup plan settings (replication, retention, and

validation of backups), refer to the "Backup" section of the product help system or guides for

Acronis Backup & Recovery 11.5 Advanced Editions.
