Arq (Trial) (Install)

Arq (Trial) (Install) is a backup and recovery application for Windows. It is intended for people who want to protect selected files or the contents of a computer using their own storage accounts or servers. The application encrypts file data on the computer before transmission, with the encryption password chosen by the user. Network transfers use SSL/TLS, and the product description states that the provider does not have access to the files.

Backups are kept in an open, documented format rather than a closed storage structure. An open-source command-line utility is available for inspecting backups and restoring files directly from cloud storage, and other users have created compatible tools such as arqinator. Arq reduces upload requirements through compression, client-side deduplication, and rolling checksums that transfer only changed parts of files. It can back up everything or selected files, including videos, files of any size, and external drives.

The Windows application is described as a native app rather than a Java-based application. Storage destinations include Amazon Cloud Drive, Amazon Web Services, Google Cloud Storage, Google Drive, Dropbox, OneDrive, an SFTP server, and a NAS. This places Arq in MirrorNest’s backup-recovery category as a Windows tool that connects backups to storage selected by the user. MirrorNest links directly to the official release instead of mirroring the installer, while the license status for this catalog entry is unknown.

Free to use — a paid version with additional features is also available.
