Plan/B - The Backup Solution Plan/B is a network aware file backup system specifically created to make the backup of files from multiple machines to a variety of devices simple. The system includes features such as comprehensive reporting, the ability to use CDROM (and soon DVD) drives across the network and centralised management. Plan/B can be deployed on Windows .
Main features:
- Backup anything, to anywhere: You can use any kind of device that Plan/B knows about (currently CDROM, Local disk, Windows Network share, FTP device) as either a source or destination. There is no limitation (as there is in DataArmour).
- Incremental mode Copy only what has changed, saving bandwith and time.
- Multiple sources, multiple Destinations: A backup may source its files from multiple machines and devices. The destinations for a backup job can also be any number of machines or devices. Thus it is now easy to have a single set of files (documents, code or other important assets) copied to more than one location using a single job. No need to clone a job anymore!
- Multi-Platform: As the system is written in Java, it will work with any machine for which there is a VM (this is true for the backup server and agents). The administration console can be run on either a Linux or Windows machine (when SWT, the GUI framework used for the console matures on OSX, the console will be able to run on that Mac as well)
- Volume spanning: If any removable destination is out of space, then it is possible to request the next volume during the backup process. A good example of this is backup to multiple CDs. Plan/B supports both the spanning of single files across multiple media, and also the saving of complete files across different media. In the first case, a large file can be split across two volumes. In the second case, only complete files are written to any volume (obviously, if the file is larger than the size of the volume, it will have to be split up).
- Flexible selection: A single job can backup whatever is deemed important to the user. The files to backup are specified by rules, which can be as simple as include everything, and complex as include all word documents, all excel spreadsheets under my docs directory, and everything NOT ending in .bak under the data directory
- Flexible scheduler: Jobs can be run whenever you like. The current scheduling implementation takes on a form very similar to Cron, but other implementations are easily added. The important point here is that the process of deciding when a backup should be run is completely separated from anything else about the backup job. This is a change from DataArmour, where the scheduling (specifically, the weekly incremental backup job scheduling) is fixed to run on a Monday, with a full backup occurring every week. In Plan/B, user defined schedules are possible.
- Statistics: The system emits various statistics while in operation, including current progress of various jobs, jobs in the run queue, current load, and recent logged events.

A type of tree, which represents sorted data in a way that allows for efficient insertion, retrieval and removal of records B+ Tree was designed to be a type of tree, that represents sorted data in a way that allows for efficient insertion, retrieval and removal of records, each of which is identified by a key.
It is a dynamic, multilevel index, with maximum and minimum bounds on the number of keys in each index segment (usually called a block or node). In a B+ tree, in contrast to a B-tree, all records are stored at the lowest level of the tree; only keys are stored in interior blocks.

Year Viewer is a free and useful widget that shows historical events.
Simply type in a date from 500 B.C. to 2005 to view the event that occured during the period. Uses historychannel.com for information.
If a year is before 1800, enter in the first date of the decade.
If a year is before 1000, enter the first date of the century.
If a year is BC, type in "[x]BC" where [x] is the first year of the century.
