Review the Prerequisites and Considerations

Verify if you have completed the following prerequisites:

Log in to the Console.
Prepare a host-based backup proxy server where you have installed Arcserve UDP Agent (Windows).
To run functions such as Preflight Check, pre/post commands, or application log purge, use one of the following credentials for the guest virtual machine:
- Built-in administrator user credentials.
- Built-in domain administrator user credentials.
- For other administrator credentials, disable the User Account Control (UAC) on the guest virtual machine.
Install the server component and create Data Stores if you want to store the backup data in the recovery point server.
Review the prerequisites to back up an Oracle database.
Review the Compatibility Matrix which provides the supported operating systems, databases, and browsers.

Consider the following points before you back up the VM:

How a volume defragmentation can affect continued backups
The volume defragmentation by Windows native tool affects the size of the block-level backups because Arcserve UDP continues to incrementally back up all changed blocks. It means that blocks that shifted during the defragmentation are included in the backup, even if no data has changed in the files. As a result, the backup size increases. This is an expected behavior.
