Starting with Data ONTAP 7.3, the maximum number of concurrent SnapVault transfers of individual qtrees on a storage system is increased. However, the maximum number of concurrent SnapVault targets has not changed.
Before Data ONTAP 7.3, the maximum number of concurrent SnapVault targets supported by a system was equal to the maximum number of concurrent SnapVault transfers possible for the system.
A SnapVault target controls the creation of a scheduled SnapVault Snapshot copy on a SnapVault destination volume. For each SnapVault destination volume that has qtrees being updated, there is a SnapVault target.
|Model||Recommended maximum number of concurrent SnapVault targets|
Although there is a maximum number of concurrent SnapVault targets, you can configure SnapVault relationships in as many volumes as required. However, at any point in time, only the qtrees in the limited number of volumes can be updated.
If the SnapVault backup throughput is limited by the bandwidth or latency of individual links between multiple primary systems and the secondary system, you can use the enhanced number of concurrent transfer limits available in Data ONTAP 7.3 and later releases to get higher overall throughput. You can use the higher limits by spreading the qtrees in the specified number of volumes.
