DataBackup is a free, open-source data-backup application for Android 7.0 and later. It requires root access and supports Magisk, KernelSU, and APatch; it provides multi-user backup support, cloud storage, and fast backups. The project is distributed under the GNU General Public License v3.0 and offers APK downloads through its releases.
backup-maker is a self-hosted, local-network backup application that mirrors selected folders in real time to multiple destinations, including internal or external drives, SD cards, router-attached USB storage, NAS devices, and shared folders on other computers. It installs only on the computer being backed up; destination systems require no software or accounts. Backups are incremental and versioned, with file history and scheduled AES-256-encrypted snapshots. An optional second backup-maker installation enables block-level, verified delta synchronization between computers running different operating systems. The project is distributed as a self-contained binary for Linux, Windows, and macOS, with no cloud service, off-site mode, telemetry, or required internet connection. Its dashboard listens on localhost, while update checks and webhook or ntfy alerts are optional.
BackUp Maker is a Windows backup application from ASCOMP Software (Germany) that creates scheduled backups of files and folders to local drives, network shares, FTP servers and removable media. It supports mirror-style and incremental/point-in-time backups with versioning, optional encryption of backup archives, and scheduling/automation features.
Droid ASC is an Android APK decompiler front end for mobile researchers and agents. It treats compiled APK and DEX data as a read-only database, querying code relationships on demand instead of building large global indexes or fully inflating all artifacts. The engine probes Deflate bitstreams directly, uses dense Huffman lookup tables to extract metadata, exploits R8's deterministic constant relocation and instruction deduplication for cross-DEX searches, and resolves bytecode offsets to methods with an O(1) instruction-location primitive. When a target is found, it extracts the target bytecode and dependencies and reconstructs a minimal self-contained DEX in memory for decompilation. It is distributed as the `droidasc` Python CLI, installable from PyPI or source. Its commands locate and decompile classes, decode `AndroidManifest.xml`, and find string, type, method, or field references across an APK's DEX entries. The README reports a demonstration against a 352 MB commercial APK in which cross-reference search took 1.79 seconds and target-class decompilation took 177 milliseconds using 141 MB of RAM.
System Data Unpacked is a macOS menu bar and windowed app that inventories the contents of macOS System Data and lets users review or delete items individually. It uses category-specific storage probes to measure simulator runtimes and devices, Xcode data, package-manager stores, developer tools, logs, virtual machines, Docker data, snapshots, application data, project build folders, and other large folders; a final catch-all probe reports large paths not claimed by another category. Each result includes its measured size, category, safety level, and available reclaim action. Safe items can be deleted, review items are moved to the Trash first, and manual items show the relevant command or settings path. Before deletion, the app displays the exact operations and can batch compatible root actions through macOS authorization prompts. It records scan and deletion history locally, provides filtering, age and growth information, optional low-space and growth notifications, a JSON command-line inventory, and an opt-in weekly automatic cleanup for Safe items. The app makes no network requests except an optional daily GitHub update check, requires macOS 14 or later, and is distributed as a signed and notarized macOS app or through Homebrew. Current versions are proprietary; versions through 0.3.7 remain MIT-licensed.
Zerobyte is a self-hosted backup automation tool for managing encrypted backups of local and remote storage. Built on Restic, it provides a web interface for scheduling, monitoring, retaining, browsing, and restoring backup snapshots across local directories and NFS, SMB, WebDAV, and SFTP sources, with storage backends such as local and cloud destinations through Rclone. It supports compression, end-to-end encryption, and fine-grained retention policies. Zerobyte is distributed as a Docker container and requires Docker and Docker Compose. Its documentation warns that the 0.x series is subject to major changes and recommends protecting internet-accessible deployments with a secure tunnel and authentication.
