Why are repositories thick-provisioned? You may have noticed that the Windows File Explorer shows the volumes as full.
AppAssure 5 and Rapid Recovery 6.x allocates all space required for a repository at once to avoid checking for space during writing to repository. It is also recommended to leave about 10 % of free disk space on the volume during the creation of the repository.
Replay 4 does not allocate disk space using thick-provisioning. Replay will allocate space using thin-provisioning.
Disks in this thick provisioned format are created with the entire size of the disk pre-allocated on physical storage at the time the disk is created. This pre-allocation means that creating a 100GB virtual disk actually consumes 100GB of physical disk space on your drives.
