Hi Bartjo,
I did use it in an multi-MD environment where systems where connected trough a Wide Area Network.
At the "central site" all the backups where stored to a harddisk using FTP. This was not automated, but always more accurate than the service providers 3 month interval saftey backup. Backup worked fine, fortunally restore never was an issue.
If you have this "backup" stored onto a Tape, CD-RW or CD-R it's also possible to relocate a copy to a save location.
