After configuring the backup job, Vembu ImageBackup launches Microsoft VSS to take snapshot of the selected disks or full machine. Then, it transfers the blocks containing data to the Vembu BDR backup server. Blocks will be compressed and encrypted before it leaving from the source machine and also backup data will be further compressed before storing it in the storage repositories. Vembu ImageBackup agent installs a driver to track changes after full backup schedule. As per incremental scheduling frequency, modifications will also be transferred to the storage repositories.
