4 Architecture details

The $iagram a(ove illustrates the architecture that inclu$es the use of TSM for Virtual Environments toperform incremental#forever virtual machine (ac*ups A ph%sical machine is use$ for the vStorage (ac*upserver- an$ is a(le to ta*e a$vantage of the SA' transport on the rea$s from the VM.are $atastores

,ac*ups are sent to the TSM server across a 4A' using a com(ination of client#si$e $e$uplication an$compression to a $e$uplicate$ file storage pool Data remains in the $e$uplicate$ file storage pool for itsentire retention an$ is never allo.e$ to migrate to another storage pool

The follo.ing summariCes *e% aspects of the architecture:

A ph%sical machine acts as the $ata mover component of the vStorage (ac*up server Thiscapa(ilit% is implemente$ in the TSM (ac*up#archive client portion of the Data !rotection for VM.aresolution

Data is rea$ from VM.are $atastores across the SA' (% the vStorage (ac*up server using theVM.are Virtual Dis* Development it >VDD? for SA' transport

The virtual machine (ac*ups are ingeste$ over the 4A' to the TSM server using client#si$e$e$uplication an$ compression

The TSM for Virtual Environments incremental#forever (ac*up capa(ilit% is use$ to *eep the amountof $ata process to a minimum (efore other $ata re$uction technologies are applie$
