Replicating over a VPN Link

[samuk]

Just wanted to know if replciation is possible out of hours over a VPN link between two sites?

[Gostev]

Sure, why not? Please clarify where exactly do you suspect the issue?

Hi Gostev,

I was thinking upload speeds the size of the replicaiton changes.

Servers include file Servers, Exchange and SQL etc..

I have done the initial replicaiton locally on the LAN, was going to take the DR server to the remote site.

Can i esitimate the size of the replciaiton looking at the size of the vrb file?

[Gostev]

Yes, this is exactly how you should do this.

VRB file sizes for replicaiton:

Exchange: 4.4GB (not sure why this is soo big)
File Server: 1.5GB
Domain Controllers: 500MB
SQL: 3GB

Upload speed of our ADSL is 0.64Mb/s - so maybe it wont finish in one night?

[Gostev]

Yes, the link is probably too slow to replicate such amount of data.
Exchange and SQL VRBs are large because these applications use transaction logs, which in turn update many VMDK blocks.

Someone (...) told me it was possible to exclude swap files by moving them into separate virtual disks. You should have some improvement then.
