Abstract
A system, signal and method for data backup. The method, comprising the steps of: identifying at least one data increment which was previously provided to a subscriber server or generated by a subscriber server and which is to be backed up; checking at least one service provider access server to determine if it has a copy of at least a portion of the identified data increment or can regenerate or replicate at least a portion of the identified data increment; and backing up the data increment using the copy or regenerated or replicated portion from the access server if it is found and otherwise using a copy sent from the subscriber server after the checking step.

A method for data backup, comprising the steps of:
- identifying at least one data increment which was previously provided to a subscriber server or generated by a subscriber server and which is to be backed up;
- checking at least one service provider access server to determine if it has a copy of at least a portion of the identified data increment or can regenerate or replicate at least a portion of the identified data increment;
- and
- backing up the data increment using the copy or regenerated or replicated portion from the access server if it is found and otherwise using a copy sent from the subscriber server after the checking step.
A system comprising an access server at an ISP, a data backup server at the ISP, and a connection to a subscriber server for Internet access and for data backup.
A system comprising:
- means for providing access to a wide area network at an ISP;
- means for backing up data at the ISP;
- and
- means for connecting to a subscriber server to the ISP for wide area network access and for data backup.
A signal embodied in a computer, the signal comprising at least one data increment identifier identifying data to backup to nonvolatile storage, and a corresponding indication of whether a copy of that data increment was found on a provider access server.
A system comprising:
- means for identifying at least one data increment which was previously provided to a subscriber server or generated by a subscriber server and which is to be backed up;
- means for checking at least one service provider access server to determine if it has a copy of at least a portion of the identified data increment or can regenerate or replicate at least a portion of the identified data increment;
- and
- means for backing up the data increment using the copy or regenerated or replicated portion from the access server if it is found and otherwise using a copy sent from the subscriber server after the checking step.
