CloudBerry Backup for WHS v1, WHS 2011 and SBS 2011 has had an update.
The add-in automates data backup directly to Amazon S3, Windows Azure and a few other cloud storage providers
Version 2.9 comes with 5 few important enhancements:
1. Cost Estimates
You can set up cost estimates per the storage account on the account configuration dialog. You can also setup the limit in GB and in $ that when reached will stop the backup. The software will automatically calculate the costs based on the current storage price offered by the storage provider. Currently Amazon S3 charge 0.125/GB per month. The software will also send an alert to the users when the storage is about to reach the limit.
2. Pre/post actions
With the latest release you can configure Pre- and Post actions that will run before and after the actual backup is running. This feature will make it easier to back up applications such as SQL Server and Exchange. You can set up a Pre-action to back up SQL Server and then you can set up a POST action to clean up the SQL Server backup directory from the older backup files.
