If inline compression is enabled on the destination storage system, all new writes to the destination storage system are compressed.
When using SnapVault with data compression, you must consider the following guidelines:
Therefore, no network bandwidth savings are achieved by data compression.
After the SnapVault transfer is complete, the post-process compression runs automatically unless the schedule is set to manual on the destination system.
