Comparison

Azivault vs Arq.

Arq is the established, cross-platform, feature-rich backup client. Azivault is a native Mac backup app built around Finder restore, mandatory encrypted repositories, and app-independent recovery.

Last reviewed: May 29, 2026

Product scope

Arq is backup software for Mac and Windows. Arq 7 is the app-only product: buy a license per computer and configure your own storage. Arq Premium is a subscription that includes Arq 7 for up to 5 computers, bundled cloud storage, and web access to backups.

Azivault is a native macOS backup app whose repository format is a first-class product surface. It backs up selected folders to folder or S3-compatible destinations, exposes restore browsing through Finder, and includes the azi CLI for app-independent verification, search, restore, export, and S3-compatible hydration.

Market maturity

Arq is the incumbent in this comparison. It has been on the market since 2009, has a long release history, and has already solved many everyday backup edge cases: changing files, APFS and VSS snapshots, multiple storage providers, external drives, network shares, retention limits, dataless files, provider validation, and immutable records.

Azivault is earlier-stage but more opinionated. Its repository and recovery model is designed around conservative write ordering, encrypted repository metadata, Finder restore, and CLI recovery. The comparison is not "which is more proven today?" Arq is. The more useful question is where Azivault is deliberately different.

Storage provider strategy

Arq has a major advantage in breadth. Arq supports many storage locations, including AWS S3 and Glacier, Backblaze B2, Dropbox, Google Cloud Storage, Google Drive, OneDrive, pCloud, SFTP, SharePoint, Storj, Wasabi, SMB/AFP network volumes, external disks, MinIO, and generic S3-compatible storage.

Azivault's provider strategy is narrower: folder and S3-compatible destinations first. That is a weakness for users who need Dropbox, OneDrive, Google Drive, or SFTP as first-class destinations, but it keeps the repository storage contract simpler and avoids provider-specific backup formats.

Repository philosophy

Both products document their backup formats. That is a meaningful similarity and a major reason Arq is a stronger comparison than Backblaze Computer Backup. Arq's documented data format covers backup sets, backup records, pack files, tree and node formats, blob locations, compressed objects, encrypted objects, and backward compatibility with older Arq data.

Azivault's repository format is younger but stricter. Missing or future repository metadata is refused rather than guessed, supported repositories are encrypted, file and directory paths are encrypted in catalog rows and checkpoint manifests, only completed catalog runs are exposed as restore/export points, and CLI restore/export is an explicit product requirement.

Encryption and metadata privacy

Arq markets strong encryption and its data format supports optional encryption. Arq's documentation describes encrypted backup records, trees, nodes, and blobs, and its privacy policy says destination credentials and configuration settings entered for backup destinations are not collected or transmitted to Haystack Software.

Azivault makes encryption mandatory for supported repositories. It uses authenticated encryption for blob content, compresses before encryption, wraps repository key material with a user-controlled recovery password, and encrypts file and directory names in catalog rows and checkpoints.

CLI and app-independent recovery

Arq includes arqc, a command-line utility for license activation, app password setup, listing backup plans, printing latest activity logs, starting or stopping plans, and pausing or resuming backups. That is useful for administration and automation.

Azivault's azi CLI is recovery-oriented. It can inspect a repository, verify it, list plans and runs, list and search backup contents, restore individual files, export whole runs, hydrate from local object mirrors, and hydrate from S3-compatible storage. Its job is not just automation; it is the recovery path if the GUI app is unavailable.

Restore experience

Arq restore is app-centered: configure the storage location, expand backup sets and records, choose a file or folder, click Restore, or drag and drop from Arq to the Desktop or Finder. It is powerful, but the restore path can feel like navigating backup internals rather than browsing files. Arq Premium adds web access to backups.

Azivault's restore model is Mac-native and repository-centered: Finder restore browsing through a read-only File Provider domain, app-mediated unlock/materialization for encrypted repositories, CLI restore/export for GUI-independent recovery, and S3-compatible hydration to rebuild a local repository before verify/export. The goal is to make restore feel closer to ordinary Finder browsing, with the repository contract still available when the GUI is not.

Dataless and cloud-only source files

Arq and Azivault have similar thinking here. Arq documents why APFS and VSS snapshots cannot capture dataless content: snapshots preserve placeholders, and reads from snapshots do not trigger provider materialization. Arq can treat dataless files as errors, skip them, or materialize and back them up.

Azivault takes the same conservative shape: report cloud-only files as errors by default, skip by choice, or download modified files from the live source path and re-evict after backup. It also avoids marking existing cloud-only files as deleted simply because bytes are unavailable locally.

Immutability and ransomware

Arq is ahead on provider-level immutability. Arq supports immutable backup records using object-lock or retention features on supported providers such as AWS S3, S3-compatible providers, MinIO, Wasabi, and Google Cloud Storage.

Azivault has strong internal safety primitives: content-addressed blobs, immutable blob semantics, completed-run restore points, cancellation rules, failed-run refusal for restore, and explicit destructive-cleanup separation. Provider-level object-lock immutability is not supported.

Scheduling, background runs, and controls

Arq has mature operational controls: hourly and daily schedules, network and interface exclusions, battery-power rules, bandwidth limits, retention limits, custom exclusions, network share inclusion, validation, and activity logs.

Azivault has a native macOS scheduler helper and power/network policies, but its operational surface is narrower. The scheduler is designed with App Group coordination, sandboxed bookmarks, shared Keychain access, and local notifications. That is architecturally careful, but Arq currently has the broader set of user-facing controls.

Business model and billing

Arq 7 is a traditional license-plus-updates model. As reviewed, Arq's pricing page showed Arq 7 at $49.99 per computer, Arq Premium at $59.99/year for 5 computers with 1 TB included storage, and additional Premium storage at $0.00599/GB/month. Arq's pricing FAQ describes additional updates after the first year.

Azivault uses App Store subscriptions. New backup runs require active trial, subscription, or grace-period access, but restore remains available regardless of billing state. StoreKit and App Store Connect own price, trial, and purchase surfaces.

When to choose Arq

• You want a proven backup app today.
• You need Windows support as well as Mac support.
• You want a storage provider Azivault does not support, such as Google Drive, OneDrive, Dropbox, SFTP, SharePoint, Storj, or native B2.
• You want mature retention, bandwidth, validation, exclusion, external-drive, and network-share controls.
• You want provider-level immutable backup records now.
• You prefer buying a license and optional update years over an App Store subscription for backup access.

When to choose Azivault

• You only need macOS and want the product to feel deeply native.
• Finder-based restore browsing matters more than a dense backup-management UI.
• You want mandatory encryption and encrypted repository metadata by default.
• You want the CLI to be a first-class recovery tool, not just an administrative utility.
• You want restore access to remain available even when backup billing is inactive.
• You prefer a narrower provider model if it keeps the repository contract easier to document and recover.

FAQs

Is Azivault an Arq replacement?

For some Mac-only users, potentially. For users who need Windows, broad provider support, Arq Premium storage, web access, or immutable backup records today, Arq is more complete.

Is Arq more similar to Azivault than Backblaze is?

Yes. Arq and Azivault are both backup applications built around user-controlled storage and documented backup formats. Backblaze Computer Backup is primarily a managed hosted backup service.

Which has better storage-provider support?

Arq. It supports many providers and protocols today. Azivault currently focuses on folder and S3-compatible destinations.

Which has better Mac integration?

Azivault has the stronger Finder-native restore concept because it uses a read-only File Provider domain for backup browsing. Arq is still a Mac app and supports drag/drop restore to Finder, but restore browsing is centered inside Arq's own backup UI.

Which has better app-independent recovery?

Azivault has the clearer app-independent recovery contract because azi is built for inspect, verify, list, search, restore, export, and hydration. Arq has a documented data format and arqc, but arqc is mainly for app administration and status.

Which has better ransomware protection?

Arq is ahead if the requirement is provider-level object lock or immutability today. Azivault has conservative repository semantics and completed-run restore points, but provider-level object-lock immutability is not supported.

Which is more private?

Azivault is stricter at the project-policy level: no custom user data collection pipeline, no automatic diagnostics upload, no app-operated relay service, and encrypted path/name metadata in supported repositories. Arq also has a strong privacy posture for app-entered destination credentials and user-controlled storage, but Arq's website, account, support, and Arq Premium add hosted-service surfaces.

Does Arq have an open format?

Yes. Arq publishes data format documentation for Arq 7 and older Arq data. That is a major strength and one reason the comparison with Azivault is close.

Does Azivault support Arq repositories?

No. Azivault and Arq use different repository formats. Azivault should not read or write Arq data unless a deliberate import/export feature is designed and tested.
