Super-easy off-site backup
Just add your folders to Arq, and Arq will back them up automatically.
It's super easy. Just drag and drop a folder onto Arq to add it for automatic backup. Drag and drop from a backup to immediately start restoring. Watch a 30-second movie
True privacy and control
Use Arq with your own Amazon Web Services storage account. Encrypt your backups with a password only you know. Haystack Software employees have no access to your data.
All encryption is done before your data leave your computer (not using Amazon's "server-side encryption").
Your backups are stored in an open, documented format. We've also delivered an open-source command-line utility called arq_restore that's hosted at github, so you can read your data anytime without depending on Haystack Software (although we're in this for the long haul, so we'll be around for a long, long time!)
The most reliable cloud storage
Arq can back up to either Amazon S3 (Simple Storage Service) or Amazon Glacier.
Amazon S3 (Simple Storage Service) is the gold standard of online storage, backed by Amazon.com, Inc, a $100B company. S3 offers 99.999999999% durability of your data. It's designed to withstand the concurrent loss of 2 data centers without losing your data.
Amazon Glacier is an extremely low-cost storage service. It offers the same 99.999999999% durability. In order to keep costs low, Amazon Glacier is optimized for data that is infrequently accessed. Initiating retrieval from Glacier typically takes 3-5 hours, and Amazon charges for retrieving large amounts of data from Glacier.
Choose S3 for fast access, or Glacier for low cost. Or mix and match, backing up some folders to S3 and others to Glacier.
iOS App
Away from your Mac? Need to grab a file from your backups? Use ArqView on your iPhone or iPad to access your backups in your S3 account.
Awesome support
We believe backup is a critical function, so we strive to fix critical issues in Arq quickly.

Storage Pricing
Arq is a one-time license fee: $29 per computer.
Amazon S3 pricing includes a AWS Free Usage Tier with 5GB of free S3 storage for 1 year. Otherwise, S3 pricing is $.095/GB per month for storage, plus some very small "per-request" fees. See pricing details
Amazon Glacier storage pricing is only $.01/GB per month! However, Glacier does charge more for "per-request" fees, so the initial backup will incur an additional charge -- approximately $.05/GB in "per-request" fees. After the initial backup, the "per-request" fees are very small.
Accuracy
Arq restores all your data and metadata correctly, unlike some other online backup offerings. Backup Bouncer is a test suite independently developed by Nathaniel Gray to verify the accuracy of backup products restoring Mac file data and metadata -- in his words, to "keep the ugly backup tools out of the club." I tested Arq and some other leading online backup offerings and the results are presented here:
Backup Bouncer Test Results
| Product | Results | |
|---|---|---|
| Backblaze | Failed 19 of 20 tests | View Results |
| Mozy | Failed 16 of 20 tests | View Results |
| Carbonite | Failed 20 of 20 tests | View Results |
| Dropbox | Failed 19 of 20 tests | View Results |
| CrashPlan | Failed 1 of 20 tests | View Results |
| Jungle Disk | Passes all tests | View Results |
| Arq | Passes all tests | View Results |
What do these results mean? For most scenarios, probably nothing. Any of those backup apps can restore your file contents -- photos, Office docs, music files. You'll still be able to view your restored photos, edit your restored Office docs, play your restored music. But the dates on the files might not be correct, for instance. Arq is built with the view that if everything is backed up and restored properly, then you don't have to learn or worry about what all the metadata are and whether or not they matter for your situation.
Other Features
Wayback Machine
Arq keeps multiple "versions" of your files — a backup history. So if you discover a file was corrupted or accidentally deleted, you can go back and get it.
Arq automatically backs up every hour or every day, depending on the schedule you choose. Only the changes are uploaded for each backup, minimizing network and storage usage.
No limits
Arq backs up everything you tell it to back up:
- It doesn’t skip videos or ignore certain file types.
- It backs up files of any size -- 4GB, 40GB, it doesn't matter.
- It backs up your external drives and your network drives.
- It doesn’t delete backups of your external drives just because you haven’t plugged them in lately.
- It doesn’t forcibly delete backups older than 4 weeks.
Perfect Complement to Time Machine
Time Machine works well and provides fast restore, but you have to remember to plug in your backup device (unless you have a Time Capsule), and it doesn't cover all scenarios:
- theft of computer and backup device
- backup while traveling (unless you bring your backup drive)
Arq backs up whenever/wherever there's an Internet connection.
Flexible Bandwidth Options
Arq can upload to S3 at maximum speed, or at a fixed transfer rate that you choose. Or choose automatic transfer rate to slow down uploads whenever you're using the Internet for other tasks.
The Story Behind Arq
I started thinking about Arq back in early 2009 because I wanted an easy-to-use backup program but couldn’t find one that worked well. I liked Time Machine and even bought a Time Capsule so I wouldn't have to remember to plug in an external hard drive. But it still only backed up when I was at home near the Time Capsule, and if my house burned down or someone stole my computer and Time Capsule my stuff would be gone. I wanted online backup, at least for my most important documents and photos.
I tried Mozy, Carbonite and Backblaze. They all offered “unlimited” size backup for a fixed fee, but the “unlimited” service had limits. I couldn't back up a network drive, for example. I couldn't keep backups of external drives reliably -- Backblaze promised to delete backups of external drives that haven’t been connected for 30 days. They were vague about durability and availability of my backups. And then there was the risk of the backup storage provider closing up shop and me losing all my backups. I'd seen that happen before (Upline, Xdrive, Omnidrive, Digital Railroad).
Amazon S3 seemed like a great place for my backup data. It's backed by the power of a large, profitable, public company. It offers clear durability and availability numbers and replication to multiple data centers. And it isn't an “unlimited” type of offering, so they don't add constraints to minimize the amount of backup data I have.
Backing up to S3 felt like real backup, but there wasn't any great software to do it.
I had been working on a project that used Amazon S3 for storage, and stored its stuff as a content-addressable storage (CAS) system, written in Java. I decided to rewrite those bits in Objective-C. Then I added logic to correctly back up all Mac-specific metadata, plus strong encryption, plus a simple but powerful Mac UI. Thus Arq was born.
It turns out lots of people were looking for something similar, and through word of mouth Arq has become very popular among Mac users. Now with the super-cheap Glacier storage option, Arq is set to grow even faster!
