Persistence is a reliable and flexible online backup solution for Mac OS X Leopard that is compatible with most Internet servers: FTP, FTPS, SFTP, WebDAV, Amazon S3, iDisk... (it even supports offline backups to external drives). Persistence is a true Mac product that preserves Finder info, resource forks, ACLs... and comes with an elegant user interface and a powerful assistant. It also provides numerous high-end features like US government approved AES-256 encryption, efficient bz2 compression, powerful exclusion rules and scheduler, support for splitting large files during network transfers, network-error recovery, individual digital signature for backed up files, multi-cores machines optimization and more. Persistence is the best backup solution for Mac OS X users who already have access to online storage, or who simply want more control than other backup products allow, without having to resort to configuring complex utilities. Persistence Basic provides most of the great features of Persistence for a cheaper price, but with a few limitations compared to the Pro version: * Total amount of backed up data is limited to 25 Gb * Backups to external drives are not available * Backups to Amazon S3 or SFTP servers are not available * Processing and transfer of multiple backup data files simultaneously is not available * Running an application, AppleScript or shell script before or after the backups is not available * The advanced interface to build complex files and directories exclusion rules is not available (only the simple interface is available) For more information about Persistence, including the list of all its innovative features, please visit http://www.persistenceapp.com.
