Determine rate of transfer for Snapmirror

jkoelker01 — Thu, 05 Jun 2025 05:27:05 GMT

I have a question in determining the transfer rate for my snapmirrors over my IPSEC VPN that traverses an internet connection. I don't know how to calculate it while it is transferring. Anyone have any suggestions? I have a FAS2240-2 while running 8.1.1 in 7-mode. I am attempting to snapmirror 8 volumes over this IPSEC vpn and it does transfer but currently I am running 3 days behind which obviously is not acceptible. I have the snapmirrors staggered throughout the day so as to hopefully not overlap but it didn't matter. Any help is greatly appreciated. Thanks.

I'd love to hear about how this question is answered. I need to know how we can determine the rate of a transfer for snapmirrors.

JKoelker -

Try using 'snapmirror status -l'.

You can see the duration and transfer size for the last transfer:

         Last Transfer Size:     1120000 KB
         Last Transfer Duration: 00:03:47

Do the math to divide the transfer size by the number of seconds in the duration.

You can also get this information from the snapmirror logs.

I hope this response has been helpful to you.
