List of backup software

Backup software refers to computer programs and tools that automate the creation of duplicate copies of data, files, applications, and entire systems to secondary storage locations, enabling restoration in cases of hardware failure, human error, cyberattacks, or other data loss events.^[1][2] These solutions are essential for individuals, businesses, and organizations to ensure data availability, compliance with regulatory standards, and continuity of operations, with features often including scheduling, encryption, compression, and incremental or differential backup methods to optimize efficiency.^[3][4] Backup software can be broadly categorized into open-source options, which are freely available and customizable for personal or small-scale use, and commercial or enterprise-grade products that provide advanced scalability, integration with cloud services, and support for large data volumes across distributed environments.^[5][6][7] Common types of backups supported by these tools include full backups, which copy all data; incremental backups, which capture only changes since the last backup; and differential backups, which record changes since the initial full backup, balancing storage needs with recovery speed.^[8] This list compiles notable backup software across platforms like Windows, Linux, macOS, and cloud-based systems, highlighting their key capabilities, licensing models, and target users to aid in selection for various backup and recovery scenarios.^[9][2]

Open-source backup software

File-level backup tools

File-level backup tools in open-source software primarily handle the copying and synchronization of individual files or directories, enabling efficient data protection without capturing entire disk structures. These tools often incorporate mechanisms like incremental backups, which transfer only files modified since the previous backup to minimize storage and bandwidth usage, and differential backups, which capture all changes since the last full backup for simpler restoration but larger subsequent sets.^[10] Such approaches are common in Unix-like environments and cross-platform applications, prioritizing granularity over system-wide imaging. One prominent example is rsync, a command-line utility originally developed in 1996 for Unix-like systems.^[11] It employs a delta-transfer algorithm that detects and transmits only the differences between source and destination files, significantly reducing data transfer volumes even for large files with minor modifications.^[12] Key features include the --delete option, which removes files from the destination that no longer exist in the source to maintain exact mirrors, and support for remote synchronization over SSH. Rsync runs on Linux, macOS, and Windows (via ports like Cygwin or WSL), making it versatile for local and network-based file-level operations.^[13] Duplicati, first released in 2009, is a cross-platform graphical and command-line tool that performs encrypted, incremental backups of files and folders.^[14] It supports zero-knowledge encryption using AES-256, ensuring that backup data remains inaccessible without the user's passphrase, even to the storage provider, while also applying compression to optimize space.^[15] Additional features include integration with protocols like WebDAV and SSH for remote destinations, automated scheduling, and verification of backup integrity. Duplicati is compatible with Windows, macOS, and Linux, facilitating secure file-level archiving to local drives or cloud storage.^[16] BorgBackup, initially released in 2015 as a successor to the Attic project, is a deduplicating archiver that creates efficient, encrypted snapshots of files and directories.^[17] It uses content-defined chunking to split files into variable-length blocks based on data patterns, enabling deduplication across backups to store only unique chunks and thus support incremental updates with minimal redundancy.^[18] BorgBackup includes authenticated encryption for security, optional compression (e.g., via LZ4 or Zstandard), and mountable archives for easy browsing. It supports Linux, macOS, and BSD systems, emphasizing command-line efficiency for automated file-level protection.^[17]

Disk imaging and system backup tools

Disk imaging and system backup tools in the open-source domain focus on creating complete replicas of disks, partitions, or entire systems at the block level, enabling full recovery in disaster scenarios. Unlike file-level backups, which target individual files and directories for selective restoration, block-level imaging copies data in fixed-size sectors or blocks, often sector-by-sector, preserving the exact structure including boot sectors, partition tables, and unused space for bit-for-bit fidelity. This approach is essential for bare-metal restores but can result in larger images unless optimized to skip unused blocks. Tools in this category typically operate from live environments to avoid locking mounted filesystems, supporting formats like raw images or compressed archives for efficient storage. The dd command, a foundational Unix utility included in GNU Coreutils, exemplifies low-level block copying for backups. It performs sector-by-sector duplication of devices or files, such as creating a full disk image with dd if=/dev/sda of=backup.img, capturing everything from the master boot record to filesystem data without interpretation. Developed as part of the POSIX standard since the 1970s and maintained by the GNU Project, dd remains integral to modern Linux distributions, with its implementation in the latest Coreutils version 9.9 released in November 2025.^[19] While powerful, it requires careful parameter tuning (e.g., bs=4M for block size) to optimize speed and avoid errors like overwriting source devices. Partclone advances block-level efficiency by imaging only used blocks within supported filesystems, reducing backup sizes compared to raw copying. It leverages filesystem libraries (e.g., e2fsprogs for ext4, ntfs-3g for NTFS) to identify and clone allocated data, skipping empty blocks and offering compression via gzip or lz4. Developed by Thomas Tsai at Taiwan's NCHC Free Software Labs starting around 2007, Partclone's latest stable release, version 0.3.38 from October 2025, includes enhancements for exFAT support and improved rescue modes for partially damaged partitions.^[20] This filesystem-specific approach enhances compatibility across Linux, Windows, and macOS partitions, making it a core component in larger imaging suites.^[21] Clonezilla, built on Partclone and DRBL (Diskless Remote Boot in Linux), provides a user-friendly live CD/USB or server edition for disk and partition imaging. It supports unicast for single-machine backups and multicast modes via udpcast for cloning to multiple systems simultaneously, ideal for IT deployments. Originating from NCHC Free Software Labs in 2004 under lead developer Steven Shiau, Clonezilla emphasizes bare-metal recovery with features like partition resizing during restore. The latest version, 3.3.0-33 released in October 2025, integrates updated Partclone for better multi-filesystem handling (e.g., Btrfs, XFS) and network booting via DRBL for centralized imaging over LAN. Its live environment ensures non-disruptive operation, with image compression saving up to 60% space in typical scenarios.^[22][23]

Cloud and remote backup tools

Open-source cloud and remote backup tools enable efficient data protection by integrating with remote storage protocols such as SFTP, FTP, and S3-compatible APIs, allowing backups to diverse backends including self-hosted options like MinIO and commercial providers. These tools emphasize deduplication, encryption, and incremental transfers to minimize bandwidth usage and storage costs while ensuring data integrity over networks. For instance, Restic implements content-defined chunking for deduplication across local and remote repositories, supporting backends like SFTP and MinIO for secure, efficient remote operations.^[24][25][26] Restic is a fast, secure backup program that creates encrypted, deduplicated snapshots to local or remote repositories, using AES-256 encryption to protect data in transit and at rest. It supports a wide range of backends, including SFTP for secure file transfers, AWS S3, Google Cloud Storage, and S3-compatible services like MinIO, making it versatile for cloud environments. Unique features include the snapshots command for listing and mounting historical versions, and the prune command for policy-based retention to remove obsolete data while preserving snapshots. Restic's latest version 0.18.1, released in September 2025, includes performance enhancements for remote backends and improved compatibility with cloud providers' security standards, such as IAM roles for AWS and OAuth for Google Cloud.^{[27][28][29][30]} Duplicity provides incremental, encrypted backups to remote stores, leveraging librsync for efficient delta encoding and GnuPG for signing and encryption to prevent tampering. It supports backends like Amazon S3, FTP, SSH/SCP, and Google Drive, enabling seamless integration with cloud services for large-scale remote archiving. A key feature is its multi-volume archive format, which splits large datasets into manageable tar volumes for reliable transfer over unstable connections. Duplicity maintains full compatibility with AWS S3 and other providers as of its latest updates, adhering to standards like GPG for end-to-end security.^[31][32][33] UrBackup operates on a client-server model for network backups, facilitating remote data protection over LAN or the internet through secure channels to a central server. It supports incremental file backups with deduplication and preserves metadata during transfers, focusing on efficient remote synchronization without native direct cloud provider integration in the open-source edition—users typically route to cloud via server-side storage. Security is enhanced by encrypted internet backups, suitable for distributed environments, with web-based management for monitoring remote clients.^[34][35]

Discontinued backup software

Open-source discontinued tools

Open-source discontinued backup tools refer to projects that were freely available under open-source licenses but ceased active development, typically indicated by the absence of new releases for over a decade, lack of security patches, and no official community forks or maintainer activity. These tools often became unmaintained due to shifting developer priorities, resource constraints, or the rise of more modern alternatives, leaving them vulnerable to unaddressed bugs and compatibility issues with current operating systems. While some remain usable in legacy environments, their discontinuation highlights the importance of community-driven sustainability in open-source software. Another discontinued tool is SBackup (Simple Backup), a lightweight GNOME-integrated suite designed for desktop environments, particularly Ubuntu, allowing users to configure file/directory selections, scheduling, and tar-based archives via a simple interface. Development ended around 2013, with the final version 0.11.6 released on September 17, 2013, lacking ongoing maintenance or forks, rendering it incompatible with newer GNOME versions and unpatched for potential vulnerabilities. SBackup's historical significance lies in its role as an early user-friendly solution for Linux desktops, emerging from a Google Summer of Code project to simplify backups for everyday users without requiring advanced scripting knowledge. Maintainer attrition, including the departure of key contributors after initial Ubuntu integration, contributed to its discontinuation.^[79] Dirvish represents a network-oriented example, functioning as a disk-based rotating backup system built on rsync for creating snapshot-like images of filesystems across local and remote hosts. The last stable release, version 1.2.1, dates to February 18, 2005, with no subsequent updates, patches, or active forks, making it unsuitable for contemporary hardware and software stacks. It innovated in tape-less backup strategies by introducing efficient rotation policies and hard-link sharing for space savings, influencing later tools in handling large-scale disk archiving during the transition from tape to disk media in enterprise environments. The project's end-of-life was driven by the original maintainer's reduced involvement and failure to attract new contributors amid evolving backup paradigms.^[80] Users relying on these discontinued tools should migrate to actively maintained open-source alternatives as of 2025 to mitigate risks, such as Restic for secure, deduplicated backups or Duplicati for cross-platform GUI support, ensuring compatibility with current encryption standards and cloud integrations. This shift preserves the open-source ethos while addressing the limitations of unmaintained software.

Proprietary discontinued tools

Proprietary backup software refers to commercial products developed by vendors with closed-source codebases, often featuring integrated support, licensing models, and specialized features tailored for personal, small business, or enterprise environments. Several such tools have been discontinued over time due to market shifts, acquisitions, or strategic pivots toward cloud-native or unified platforms. This section examines notable examples, highlighting their discontinuation timelines, acquisition backgrounds, key historical innovations, and available options for users post-end-of-support as of 2025. One prominent example is Mozy, an early cloud-based backup solution originally developed by Berkeley Data Systems and later acquired by Dell Technologies in 2012 for an undisclosed amount to bolster its data protection portfolio. Mozy pioneered consumer-friendly online backups with features like unlimited storage tiers and automatic versioning, emphasizing seamless cloud synchronization for personal and small business users since its launch in 2005. Following Dell's acquisition of EMC in 2016, which integrated Mozy into broader enterprise offerings, Carbonite acquired Mozy from Dell on March 19, 2018, for $145.8 million to expand its endpoint protection capabilities.^[81] However, the service faced end-of-sale in May 2019, with full end-of-life (EOL) announced for January 8, 2020, superseding it with Carbonite Endpoint Protection.^[82] The legacy Mozy Backup software (version 2.28.2 for Windows and 2.17.3 for Mac) became unsupported after EOL, leaving local installations without updates or security patches. Mozy's historical strength lay in its early adoption of hybrid cloud backups, allowing users to combine local caching with remote storage for faster restores, a feature that influenced modern services like IDrive and Backblaze. As of 2025, post-discontinuation options include exporting archived data via Carbonite's migration tools during the transition period (though no longer actively supported) or manually restoring to third-party software such as Acronis True Image for ongoing management; Dell recommends contacting support for best-effort assistance on pre-EOL backups, but no new data exports are facilitated.^[82] Symantec Backup Exec Small Business Edition (SBE), a streamlined version of the flagship Backup Exec suite, was designed for small to medium-sized enterprises with simplified licensing and agent-based protection for Windows servers, virtual machines, and remote offices. Launched in the mid-2000s under Symantec (following its 2005 acquisition of Veritas Software for $13.5 billion), SBE emphasized cost-effective deduplication and agentless imaging for NAS devices, reducing deployment overhead compared to full enterprise editions.^[83] Veritas Technologies, which regained independence from Symantec in 2016, phased out SBE support with an EOL date of July 6, 2015, converting active licenses to perpetual Silver editions of the standard Backup Exec to consolidate offerings under a unified platform.^[84] This discontinuation aligned with Veritas's shift toward capacity-based licensing for broader hybrid environments, rendering SBE's tailored small business agents obsolete. Historically, Backup Exec (including SBE) innovated with agentless backups via network-based discovery, enabling non-intrusive protection of VMware and Hyper-V hosts without installing software on each VM—a technique still echoed in tools like Veeam Backup & Replication. By 2025, users of legacy SBE installations face no vendor support, but data can be exported using Backup Exec's built-in restore wizards to compatible formats like VHD or TAR for migration to active Veritas products or alternatives such as Rubrik; Veritas provides no patches for versions beyond 2014, urging upgrades to Backup Exec 22 or later for continued compatibility with modern OS like Windows Server 2025.^[85] Another key case is Norton Ghost, a disk imaging tool originally created by Murray Haszard and Binary Research International in 1995, renowned for creating bootable clones of entire drives to floppy disks or CD-ROMs in the pre-cloud era. Acquired by Symantec in 1998 for $25 million to enhance its utilities lineup, Ghost evolved into Norton Ghost 15.0 by 2009, incorporating features like incremental imaging and P2V conversions for virtualization migrations. Symantec discontinued consumer sales of Norton Ghost on April 30, 2013, citing overlaps with emerging cloud recovery tools and a pivot to Norton Utilities Premium, with full support ending June 30, 2014.^[86] The enterprise variant persisted briefly as Symantec Ghost Solution Suite until 2020, but the core proprietary imaging engine for personal use was retired. Ghost's legacy includes pioneering sector-by-sector cloning, which minimized data loss in hardware failures and set standards for tools like Clonezilla (though open-source). In 2025, legacy Ghost images (.gho or .v2i files) remain restorable on compatible Windows versions up to 10 using the final 15.0 software, but lack security updates; users can convert images to open formats like ISO via third-party utilities such as PowerISO or migrate to active alternatives like Macrium Reflect for ongoing imaging needs, as no official export paths exist post-EOL.^[87]
