->When the trim is performed within the guest OS, the tracking of incremental blocks is reset, resulting in a full backup. The trim within the guest OS releases unused blocks of the virtual disk (VHDX) and optimizes the disk size. However, this reduces the size of the VHDX and changes the SequenceNumber of the tracked incremental blocks, resulting in a full backup size. Unless the purpose is to improve the efficiency of storage on the Hyper-V host side, we recommend you  to stop the trim process within the guest to avoid an increase in backup size.

 You can use Azure Backup Server to recover the data you've backed-up to a Recovery Services vault. The process for doing so is integrated into the Azure Backup Server management console, and is similar to the recovery workflow for other Azure Backup components.

 ## What is the Backup Schedule?
 
 The backup schedule indicates the frequency of the backup operation. For example, the settings in the following screen indicate that backups are taken daily at 6pm and at midnight.

 System Center Data Protection Manager (DPM) enables you back up a SharePoint farm to Microsoft Azure, which gives an experience similar to back up of other data sources. Azure Backup provides flexibility in the backup schedule to create daily, weekly, monthly, or yearly backup points, and gives you retention policy options for various backup points. DPM provides the capability to store local disk copies for quick recovery-time objectives (RTO) and to store copies to Azure for economical, long-term retention.
