1.Create a first session with -diff option#symclone f create -copy/-precopy diff sid nopNote : This session will be full copy too. only thing is subsequent copies can be created with recreate option & they'll be just differential and fast.2. Activate the session.#symclone -f activate -sid -consistent -nop3. for subsequent point in time clone creations. you don't(shouldn't) need to terminate the session. instead Recreate the same session using below and activate them using activate.#symclone -f recreate -sid nop4. Activate it for start copying blocks. This should be fast.#symclone -f activate -sid -consistent -nopsymclone f create -copy/-precopy diff sid nopintecsv.splitexport PATH=$PATH:/opt/emc/SYMCLI/binBCV1_PAIRFILE=/etc/EMC_Scripts/bcv1_pair.file#split#symclone activate -g intec_bcv1_dg -consistent -sid 121symclone activate -f $BCV1_PAIRFILE -consistent -sid 121#query#symclone -g intec_bcv1_dg query -sid 121symclone -f $BCV1_PAIRFILE query -sid 121intecsv.syncexport PATH=$PATH:/opt/emc/SYMCLI/binBCV1_PAIRFILE=/etc/EMC_Scripts/bcv1_pair.file#sync/recreate#symclone recreate -precopy -g intec_bcv1_dg -sid 121symclone recreate -precopy -f $BCV1_PAIRFILE -sid 121 -nop#query#symclone -g intec_bcv1_dg query -sid 121symclone -f $BCV1_PAIRFILE query -sid 121
