Arq

Arq 7.38.6.0 from Haystack Software LLC is a cross-platform backup utility designed to protect data on macOS and Windows PCs by creating versioned, encrypted archives in user-controlled destinations such as Amazon S3, Google Cloud Storage, Dropbox, OneDrive, SFTP servers, or local disks. Released as the thirteenth iteration since the product’s debut, the application continuously monitors selected folders, detects changed blocks, and uploads only incremental differences, minimizing bandwidth use while maintaining a complete timeline of recoverable snapshots. Typical deployments include safeguarding personal photo libraries, off-site replication of small-business file servers, and long-term retention of project folders for creative professionals who require point-in-time restoration across multiple years. Administrators can define hourly, daily, or custom schedules, apply retention policies that thin older versions automatically, and impose client-side AES-256 encryption with private keys that remain outside the cloud provider’s control. Network throttling, email reporting, and scriptable pre/post-backup hooks accommodate unattended operation on laptops, desktops, and headless workstations. The software operates within the “Backup & Restore” category and is compatible with NTFS, APFS, ExFAT, and FAT32 volumes, preserving extended attributes, resource forks, and Windows ACLs so that restored data mirrors the original file system semantics. Version 7.38.6.0 introduces refinements to deduplication algorithms and improves credential management for OAuth-based storage endpoints. Arq is available for free on get.nero.com, with downloads delivered through trusted Windows package sources such as winget, always serving the latest build and enabling batch installation alongside other applications.
