Off Site Backup of UrBackup Server

Looking to use UrBackup to backup another UrBackup Server backed up files.

Site A:
Is my Primary Urbackup Server which backups all MS Server’s that have Home Directory’s on it.
Site B:
Is my Off Site backup and I would like to have UrBackup setup there to backup Site A backed up files.

Would there be any issues installing UrBackup client on my Site A UrBackup Server running Windows Server?
