How can you throttle SnapVault updates and baseline transfers so that the primary or secondary is not transmitting data as fast as it can?

• A. Use the snapvault throttle command.
• B. SnapVault does not support throttling of network throughput.
• C. Use the -k option in the snapvault initialize command.
• D. Use the -k option in the snapvault start or snapvault modify commands.

Answer: (D)

To keep network links from being saturated, you throttle the data rate of SnapVault transfers rather than blasting everything as fast as possible. The way to apply this throttle is with the −k option on the commands that start or adjust a transfer. By using snapvault start -k (and later snapvault modify -k if you need to change it), you cap the transfer rate at a set number of kilobytes per second. This applies to both baseline transfers and subsequent updates, so you can slow down the initial baseline copy or any incremental transfers as needed. The initialize command doesn’t accept throttling via this option, and there isn’t a separate throttle command, which is why the other choices aren’t correct.
