Snapmirror initialization over a 1gb link

Sanaman — Wed, 04 Jun 2025 09:46:47 GMT

Hi,

Planning to migrate 40tb data over 1 gb link (shared with other activities) using snapmirror. As per my test it will about 20days to finish the initialization. One of the option coming to my mind is using tapes to initialize the relationship. But my source FAS2620 and destination FAS8300 don't have any tape drives attached. Has anyone done this before, what other options are available?

Thanks in advance.

Thanks for the link.

It is my understanding that using USB disk for SMTape not supported by NetApp and it is slower than the transfer over the wire. Could you confirm pl?

Thanks

- 5 MB/s is slower than most WAN connections

- not recommended and is not supported.

That's what I thought. Thanks for your time.
