Backblaze is one of the best-known cloud backup services for Mac because it is simple: install the app, let it back up your user data and connected external drives, and pay a flat price for unlimited storage on one computer.

That simplicity is exactly why many Mac users choose it. It is also why some users eventually look for alternatives. Arq gives you more control by backing up to your own cloud storage accounts, SFTP servers, NAS shares, or external disks. IDrive bundles cloud backup, sync, mobile access, external drive backup, and multi-computer plans. Apple's Time Machine is the free local backup baseline built into macOS. Carbon Copy Cloner is the best Mac-native local backup app when you want precise tasks, verification, snapshots, and backups you own.

This guide compares Backblaze alternatives for Mac across cloud storage, local backup, external drives, version history, privacy, restore options, setup effort, pricing, and the kind of Mac user each one fits best.

Quick Verdict

Choose Backblaze if you want the easiest off-site backup for one Mac. It is strongest when unlimited cloud backup, automatic operation, connected external drive backup, web restore, shipped-drive restore options, and simple pricing matter more than fine-grained destination control.

Choose Arq if you want cloud backup without handing storage choices to one backup vendor. It is the best Backblaze alternative for users who already have storage on Backblaze B2, AWS, Google Drive, Dropbox, OneDrive, Wasabi, SFTP, NAS, or another S3-compatible service.

Choose IDrive if you need one cloud backup account for several computers and devices. It is more plan-driven than Backblaze, but useful for households, freelancers, and small teams that want Mac, PC, mobile, external drive, and NAS-oriented backup under one storage quota.

Use Time Machine if you want the free built-in safety net. It is not an off-site cloud backup service, but it is still the easiest way to recover yesterday's file, migrate a Mac, or keep automatic local version history.

Choose Carbon Copy Cloner if you want a controlled local backup strategy. It is better than Backblaze for precise copies, external disks, cloud-only file handling, APFS snapshots, verification, and keeping backup storage under your control.

Feature Comparison

Backblaze

Backblaze is the easiest recommendation when someone asks, "What should I use so my Mac is backed up off-site?" It is intentionally less configurable than Arq or Carbon Copy Cloner. That is part of the product.

The current Backblaze Mac page describes automatic backups, secure encrypted backup, off-site storage, unlimited storage, unlimited file size, external drive backup, native Mac software, mobile access, optional private encryption key, two-factor verification, web restore, restore app access, and shipped-drive restore options. Backblaze also says the Mac app backs up user-created data, including data on physically connected external drives, while excluding operating-system files, applications, temporary files, and some file types by default.

That makes Backblaze a strong fit for people who do not want to design a backup system. If your Photos library, documents, project folders, exports, tax files, and external photo/video drives need an off-site copy, Backblaze removes many decisions. You do not have to buy separate cloud storage, calculate per-GB object-storage fees, or remember which folders to include.

The tradeoff is control. Backblaze Computer Backup is not an archive service, a Dropbox-style sync tool, a general S3 browser, or a local clone. It mirrors the current state of the computer and attached drives according to its backup rules. If you disconnect an external drive for too long, delete local data, or need custom multi-destination retention, you need to understand the limits before relying on it alone.

Backblaze Personal Computer Backup currently costs $9/month, $99/year, or $189 for two years. Every account includes 30-day version history, Backblaze currently lets users enable one-year version history for free, and forever version history costs extra for versions retained beyond one year.

Choose Backblaze if you want the least fussy off-site backup for one Mac and can accept the service's mirror-style assumptions.

Arq

Arq is the strongest Backblaze alternative for Mac users who want control over storage. Instead of sending backups only to Arq's own cloud, Arq can back up to many destinations, including Backblaze B2, AWS, Google Drive, Google Cloud, Dropbox, OneDrive, SharePoint, Wasabi, SFTP, Minio, other S3-compatible storage, external drives, and NAS shares.

That storage flexibility matters. A photographer might keep one encrypted backup on a NAS and another in Backblaze B2. A developer might use S3-compatible storage already paid for by a business. A privacy-sensitive user might prefer storage they can audit, migrate, or replace without changing the backup app. Arq's current product page emphasizes end-to-end encryption, versioned backups, point-in-time recovery, compression, deduplication, block-level incremental backup, multiple destinations, no vendor lock-in, and restoring directly from the app.

Arq is not as hands-off as Backblaze. You have to choose where backups go, how much storage costs, how retention works, and whether restore bandwidth or object-storage operations will matter. That is the price of flexibility. For users who want one flat bill and no storage math, Backblaze is easier. For users who want control, Arq is much more adaptable.

Pricing currently has two main paths. Arq 7 costs $49.99 per computer as an app-only license with 12 months of updates included, and backs up to storage you provide. Arq says this price increases to $59.99 on September 1, 2026. Arq Premium costs $5.99/month or $59.99/year for up to five computers with 1 TB of included storage, with additional storage billed separately. Arq says Premium increases to $6.99/month or $69.99/year on the same date.

Choose Arq if you want encrypted cloud backup but prefer to own the storage decision.

IDrive

IDrive is the Backblaze alternative to consider when one computer is not the whole problem. Its current pricing and feature pages frame IDrive around backup for multiple computers and devices, cloud storage quotas, external drive and NAS support, continuous backup, disk image backup, sync through Cloud Drive, web/mobile access, sharing, and physical shipment through IDrive Express on eligible plans.

The main difference from Backblaze is the pricing model. Backblaze gives one computer unlimited backup for a flat price. IDrive gives an account a storage quota and can cover multiple computers or devices within that quota. That can be better if you have a MacBook, an iMac, a Windows PC, and mobile data that together fit inside one plan. It can be worse if one Mac has many terabytes of media and would quickly outgrow a quota.

IDrive also includes more adjacent features than Backblaze Personal Backup. Cloud Drive sync, sharing, server-oriented add-ons, NAS support, team plans, and business plans make it broader. That breadth is useful for some households and small teams, but it also makes the product feel less single-purpose than Backblaze.

The restore story is also different. IDrive supports desktop, web, and mobile access, and its pricing page describes IDrive Express physical backup or restore shipments on eligible plans. That can matter when uploading or recovering terabytes over a home connection would take too long.

IDrive currently has a free 10 GB Basic plan. The Personal plan starts at 5 TB; the pricing page currently lists a monthly option at $11.99/month, plus annual and two-year options with first-term promotions and standard renewal pricing shown separately. Because IDrive pricing changes often through term length and new-customer offers, check the live pricing page before choosing it.

Choose IDrive if you want one quota-based cloud backup account for several computers and devices.

Time Machine

Time Machine is not a direct cloud backup competitor, but it belongs in every Mac backup comparison because it is the backup most people should enable first. It is built into macOS, requires no subscription, and is good at the most common restore need: recovering a file, folder, or earlier version from a local backup disk.

Apple's current support page says Time Machine can automatically back up files including apps, music, photos, email, and documents to an external or supported network disk. It keeps hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for previous months, deleting the oldest backups when the disk is full. Current macOS versions also let users adjust backup frequency.

The biggest advantage is friction. Connect an external drive, choose it as a backup disk, optionally encrypt it, and let macOS work. Time Machine is also useful during Mac migration and broad recovery because Apple designs macOS around it.

The limitation is location. A Time Machine disk sitting next to your Mac does not protect you from theft, fire, flood, or losing both the computer and the drive in the same bag. Time Machine is also less configurable than Carbon Copy Cloner and less useful than Arq for off-site encrypted cloud destinations.

Use Time Machine as the first layer, not the only layer, if your data matters. Pair it with Backblaze, Arq, IDrive, or another off-site strategy.

Choose Time Machine if you want automatic local version history before spending money on a larger backup plan.

Carbon Copy Cloner

Carbon Copy Cloner is the local-backup power tool in this comparison. It is not trying to be a hosted cloud backup subscription. It is trying to make controlled Mac backups better than a simple Finder copy or a one-size-fits-all Time Machine disk.

The current CCC 7 page highlights precise copy control, smart updates, APFS snapshots, backup verification, task history, cloud-only file handling for services such as iCloud, Google Drive, Dropbox, OneDrive, and Box, encrypted and private backup workflows, guided setup, and a personal household license. CCC can back up a whole data set, a selected folder, an external disk, or a carefully filtered task to storage you control.

That makes it an excellent companion to Backblaze rather than only a replacement. Backblaze covers off-site disaster recovery. CCC can keep a fast local backup that you can browse, verify, rotate, clone, or take offline. For media workers, developers, admins, and anyone with external project disks, that local control is valuable.

The tradeoff is that CCC does not include hosted cloud storage. If you want off-site backup, you need to provide the destination through disks, network storage, or another service. It also asks you to think in terms of tasks, schedules, volumes, snapshots, and verification. That is an advantage for careful users and an obstacle for people who just want a background cloud backup.

Carbon Copy Cloner 7 currently costs $49.99 for a personal and household license for non-commercial use, with a 30-day trial available. The current download page says CCC 7 supports macOS Ventura 13.1, Sonoma, Sequoia, and Tahoe.

Choose Carbon Copy Cloner if your backup plan needs local control, verification, and fast restore paths that do not depend on downloading from the cloud.

Which Backblaze Alternative Should You Use?

Use Arq if Backblaze feels too locked down. It is the best fit when you want encrypted backup to storage you choose, especially if you already understand cloud storage costs.

Use IDrive if your problem is several computers and devices rather than one Mac with unlimited storage needs. It is more quota-driven, but that can be better for households and small teams.

Use Time Machine if you have not enabled any backup yet. It is free, built in, and still the lowest-friction way to recover recent files.

Use Carbon Copy Cloner if you need a dependable local backup that you can verify, browse, rotate, and control. It is especially useful beside an off-site service.

Stick with Backblaze if you want the easiest off-site backup and your setup is one Mac plus physically connected external drives. It is popular for a reason: it turns a complicated habit into a recurring background task.

The practical choice is usually a pair, not a single winner. A good Mac backup setup often looks like Time Machine or Carbon Copy Cloner locally, plus Backblaze, Arq, or IDrive off-site.

Final Verdict

Backblaze is the best simple off-site backup for one Mac. It is hard to beat if you want unlimited cloud backup, automatic operation, connected external drive backup, and clear pricing without building your own storage plan.

Arq is the best Backblaze alternative for control. It is the right choice when you want encrypted backup to your own cloud storage, NAS, SFTP server, external disk, or multiple destinations.

IDrive is the best multi-device cloud alternative. It makes more sense when several computers and devices fit inside one storage quota.

Time Machine is the best free first layer. Every Mac user should consider it before paying for anything else, but it should not be your only backup for irreplaceable data.

Carbon Copy Cloner is the best local power-user layer. It gives Mac users precise tasks, snapshots, verification, and storage ownership.

My practical recommendation: use Time Machine or Carbon Copy Cloner for local recovery, then choose Backblaze for the easiest off-site backup, Arq for bring-your-own-storage control, or IDrive for quota-based multi-device backup.
