Does any one know how to seed a remote storage device to speed the initial backup to a remote site over a slower WAN connection? I have been able to perform this with other solutions but hoped this was possible with XSIbackup.
Thanks,

What do you mean by "seed"?. I guess you are talking about performing differential backups. I have seen that terminology being used by other manufacturers, but they mainly refer to a especial scenario for a differential backup.
You can achieve differential backups by using the [b]OneDiff[/b], [b]XSITools[/b] or [b]Rsync[/b] backup programs.

Seeding is taking a physical copy of the vmdk on a mobile device to the remote site, copy it into the storage. then when oneDiff runs the first time, it doesn't have to replicate the complete file across the slow WAN, but uses the copy for block checking and transmit the changes.

Yes, It's just a particular scenario for a differential backup.
XSIBackup does not care much about how the previous data got to the other end. So, you can:
Make a OneDiff, XSITools or Rsync backup through a fast LAN and then move the whole host somewhere else in the world. Change the target IP for the backup and XSIBackup will continue to backup those VMs.
You can instead just move the disk to some other host, just make sure you change the paths accordingly.
In case of using OneDiff, you rely on top of the ESXi snapshot feature, which is not 100% functional in Windows servers when requiring quiescing. So, if you loose synchrony in a OneDiff backup, due to a failed snapshot operation per instance, you can use an Rsync backup job to re-sync data by using the Rsync delta algorithm, it's much slower, but it will allow you to keep both ends up to date by just exchanging the diff bytes.
