Dear Sir,

I’ve a question about TrueCopy.


I saw two kinds of TrueCopy

  • TrueCopy Extended Asynchronous Replication
  • TrueCopy Remote Synchronous Replication


For TrueCopy Extended Asynchronous Replication, there is a description about the technology in the document.

“Cycle time is the interval between updates from the P-VOL to the S-VOL.

Cycle time is set to the default of 300 seconds during pair creation.”

I presume the minimum replication interval is 300 seconds (i.e. 5 minutes), is it right?


But for “TrueCopy Remote Synchronous Replication”, I did not find similar description.

Does it mean TrueCopy Remote Synchronous Replication is “continuously” replication? No interval can be configured, is it right?

May I say it a kind of “HA” with TrueCopy Remote Synchronous Replication?
