Select a source volume and check its capacity.
Prepare a target volume and set it as backup volume. The capacity of target volume
should be larger than the source one.
Plan the schedule local clones, determine the cycle of executing clone tasks. It can be
hourly, daily, or weekly.
Planning the Remote Replications
To plan the remote replications, except to select a source volume in source unit and prepare
a target volume which the source replicates to in target unit, you have to prepare the
information of iSCSI port IP addresses to transfer the data. In addition, according to the
network bandwidth, determine the transfer rate at peak and off-peak hours.
Select a source volume and check its capacity in source unit.
Select a source iSCSI port to send the replication data.
Prepare the information of iSCSI port IP addresses in target unit to receive the
replication data. Also prepare CHAP username and password if the target unit is
enabled CHAP authentication.
Prepare a target volume and set it as backup volume in target unit. The capacity of
target volume should be larger than the source one.
Plan the schedule remote replications, determine the cycle of executing replication
tasks. It can be hourly, daily, or weekly.
Define the off-peak hours and plan the transfer rate at peak and off-peak hours.
