=====Restore=====
=====Restore=====
The backup service provided by the server will allow several types of restoration, based upon the child's needs.
Full restore functionality provides a fail-safe for the children. Though the ruggedness of the laptops should minimize the need for a full restore, any event which causes permanent loss of any or all data on a laptop can be recovered from nearly completely from the backup files. These files also provide a means of restoring the child's settings and data should they for any reason ever need a new laptop. In practice, this is a temporal restoration, recovering all files stored on the backup server within a given time period from the present.
The backup server will also provide partial restores, which allows children to select individual objects and entries to recover. Any recovered items will appear as a new Journal entry on the date of recovery. This form of restoration will occur with much greater frequency, purposed mainly to restore an accidentally deleted entry from a week or so ago, while flexible enough to restore any entry ever backed up on the server.
In addition to these hard restoration methods which physically copy the data back onto the children's laptops, the server will also provide soft restore functionality, allowing children to browse through the backups on the server directly from within their Journals. Since this browsing functionality will integrate cleanly with the entries stored on their own laptops, the children will be able to search, filter, sort, and view anything they ever without having to think about the technicalities of the data's physical location. Apart from a visual indication within the entry, the experience of browsing through backups will be seamless. Using the temporary restore method, children can browse through their past creations, much as we might browse through a photo album. They will have full ability to resume any instance of an activity, to view its contents. A copy-on-write approach will be taken, so that if a child attempts to modify a temporarily restored item, it will behave identically to a partial restore for that Object, writing the modified revision into a new journal entry.
