Offsiter is an archiving application that compresses files and sends them encrypted to offsite e-mail accounts. Such offsite storage offers far greater security than conventional storage mechanisms such as CD ROM, tapes, and hard drives, all of which are prone to theft or damage. You can use any e-mail account, including the free ones provided by Yahoo, Microsoft, and Google. You can create the compressed archives using Offsiter or any other compression application. However, Offsiter does offer you the rare option of archiving only those files that have changed since the last archive was created. This drastically reduces the size of subsequent archives. When the archive is sent to an e-mail account, it is divided into separate e-mail attachments so that the provider's size limit for e-mails is not breached. Each attachment is encrypted to prevent hackers gaining access to your files by intercepting them during sending or by breaking into your e-mail account. If you need to recover an archive, simply download the original sent attachments to your computer and use Offsiter to decrypt and merge them to recreate the original archive.
