Hi,
a backup will be done with remote backup via Internet to www.backup-connect.nl.
The question is in fact: can the snapshot, normally backed up to tape, be backed up incrementingly or differential? Once a week a full backup will be performed to the external backup provider, all other days the backup will be differential/incremental.
The most interesting of this all: is a restore from the CPS possible in this case? As stated in the original question, 3th party backup is capable of in-file backup.
Hope this clears the question.
