2. The replication job can be scheduled to run by hour, by day, by week or by month. The execution time can be configurable per user's need. If the scheduled time of execution is arrived but the pervious replication job is stilling going, the scheduled execution will be ignored once. Figure 5.11.20 • Configure the snapshot space The Replication uses Snapshot technique of D-LINK, to help user to replicate the data without stop accessing to the source virtual disk. If the snapshot space is not configured on the source virtual disk in advance, the IP SAN storage will allocate snapshot space for the source virtual disk automatically when the replication job is created. The default snapshot space allocated by the IP SAN storage is two times the size of source virtual disk. If the free space of the RAID group which the source virtual disk resides in is less than double size of the source virtual disk, the replication job will fail and pops up the error message. To prevent this problem, user has to make sure the RAID group has enough free space for the snapshot space of source virtual disk, or user has to configure the snapshot space of the source virtual disk manually before the replication job is created. 1. To configure the snapshot space settings of Replication, click the "configuration" button. 120
