storeBackup is a backup utility that stores files on other disks. It's able to compress data, and recognize copying and moving of files and directories (deduplication), and unifies the advantages of traditional full and incremental backups. It can handle big image files with block-wise changes efficiently. Depending on its contents, every file is stored only once on disk. Tools for analyzing backup data and restoring are provided. Once archived, files are accessible by mounting file systems (locally, or via Samba or NFS). It is easy to install and configure. Additional features are backup consistency checking, offline backups, and replication of backups.
S3QL is a file system that stores all its data online. It supports Amazon S3, Google Storage, and OpenStack and effectively provides you with a hard disk of dynamic, infinite capacity that can be accessed from any computer with Internet access. S3QL provides a standard, full featured Unix file system that is conceptually indistinguishable from any local file system. Additional features include compression, encryption, data de-duplication, immutable trees, and snapshotting, which make it especially suitable for online backup and archiving. The design favors simplicity and elegance over performance and feature-creep. Care has been taken to make the source code as readable and serviceable as possible. Solid error detection, error handling, and extensive automated test cases are provided.
GNU xorriso creates, loads, manipulates, and writes ISO 9660 filesystem images with Rock Ridge extensions. Files can be copied in and out. The session results get written to optical media or to filesystem objects. Rather than needing external tools for ISO 9660 production and CD/DVD/BD burning, it is a static compilation of libburnia-project.org. Thus GNU xorriso depends only on fundamental operating system facilities.
UrBackup is an efficient client/server backup system for Linux and Windows. A client for Windows lets you backup open files and complete partition images. Incremental and full image backups are stored to disk in a efficient way with file level de-duplication on either Windows or Linux servers. An easy-to-use server Web interface lets you analyze storage usage, view logs, modify settings, and browse backups. Backup images can be restored using a prebuilt live Linux CD based on KNOPPIX.
rdup is a utility inspired by rsync and the Plan9 way of doing backups. rdup itself does not backup anything; it only prints a list of the names of files that have changed since the last backup. It also handles files that are removed, allowing for correct incremental backups. Auxilary script that implement a backup strategy are included.
DIASER is a cloud storage class combined geo-data replication, long-term archive system, and WAN vault application. Manage long term mixed data archives generated by existing backup software. Ensure availability using commodity hardware. Retain administrative and financial control. It combines a disk-based backup volume management system and triple redundancy with a storage architecture designed to structure months to years of long term sustainable archiving space. It is a quick and low-cost way to make an environment more robust by backing up data in multiple places. This replication also provides fast retrieval of archived data from all node hosting locations. A Perl installer creates the system. Nodes can be dedicated to storage or used for existing services over unused bandwidth. DIASER works in user space over SSH.
