A free portable application to take backup of your files in a plain paper

To day I came across a software which enable to take the backup of files in a plain paper. This is a free application developed by Mr Olly, which allows backup of your files on the ordinary white paper in the form of the over sized bitmaps. If you have a good laser printer with the 600 dpi resolution, you can save up to 500,000 bytes of uncompressed data on the single A4/Letter sheet. Integrated packer allows for much better data density.

setup and installation

It is a light weight portable application.No installation is required.Run the program and go to the Options menu. A option dialog box can be seen like this

• Dot density: This is the most important parameter. It determines the size of the data bit on the paper and must be at least two times lower than the physical resolution of your printer. If your printer with 600dpi resolution then set the value to 300
• Dot size: Dots must be clearly distinguishable from each other.70% is usually the best option.
• Compression: Compression  is always good, because it reduces the size of the bitmap, unless your file is already packed. Use fast compression if your computer is really, slow, and maximal compression in all other cases.
• Redundancy: helps to recover partially damaged data. Redundancy 1:5 means that for every 5 consecutive data blocks, if one block is completely unreadable, PaperBack will be able to restore it. To reduce damages caused by coffee pots and other common dangers, blocks are distributed around the page. Higher redundancy decreases page capacity but improves reliability.
• Header and footer : Allow PaperBack to print useful information about the file, like file name, its size, date of last modification, page and recommended scanner settings.
• Auto save on completion: When last page is scanned (order is not important) and autosave option is activated, PaperBack will ask you to select location where restored file will be saved. If this option is unchecked, you must press Save button when recognition is finished – convenient if your scanner has automatic feeder and you scan several backups (up to 5) at once.
• Quality: Activate Determine best quality, and PaperBack will report the real data quality. Of course, this costs time.
• Data encryption and password: options set data encryption  and whether the file need to be password protected.

Printing

Set the printer settings, which may be differ from printer to printer.Select available best print option. If you are using ink jet printer then check the nostle  alignment and disable bi directional printing. Laser printer is always the best option click on the print menu and select the desired file to print.Remember the program can select only files, not folders. if you have more than one file then zip the folder using the appropriate utilities. Then takeout prints in good plain white paper The printout of a file is look like following:

Restoring the backup

Restoration can be done through any scanner attached to the pc. Connect the scanner to the PC. Place the paper the scanner, select gray scale or colour option. Turn off all image optimizations, like sharpening – PaperBack uses its own optimization techniques better suitable for this particular case.If backup consists of several pages, the order in which they are scanned is absolutely unimportant. Bottom line in the tab displays list of unscanned or incomplete pages. If some page is unreadable, change its placement, resolution and/or brightness and contrast. After all pages are scanned, press on Save to write restored file to the disk. If backup is encrypted, you will be asked to enter the password.
