I have been using Crashplan as my backup tool since February 2015. What is ARQ (Automatic Repeat Request) There are two ways of doing error control namely error detection and error correction. At the time, I bought into their four year family plan (=multiple computers) for 429.99 USD. But Crashplan turned out to be a memory hog (especially if you have a multi-terrabyte harddrive) and it was clear that I want a better solution so I started looking for an alternative in 2016, one year before the subscription was supposed to end. I focused on software solutions that would allow me to back up to whichever storage I want so that I would be in better control of my data (Crashplan at some point deleted an entire backup of mine because the computer it was associated with hadn’t backed up anything for more than six months. Apparently it was in line with their Terms of Service, but deleting backups is not a goof thing to do for a backup company). I spend a lot of time testing various solutions, including Arq, Goodsync, Cloudberry, SyncBackPro and Syncovery. Goodsync, Cloudberry and SyncBackPro were out pretty quickly :Ĭloudberry cannot handle backups larger than 1TB unless you buy the enterprise version for 300 USD. Goodsync had crap customer service (reasonably fast response, but useless and not answering my question) and it was designed more for syncing than for backing up (although backing up is possible). (Well actually you can change the source folder and the original stuff in the backup will remain but will no longer be backed up.) With SyncbackPro, the restore process seemed rather complicated and once a folder is selected as the source, you cannot add other folders to that backup job. Syncovery was very promising but I kept bumping into bugs and errors and I spend a hell of a lot of time helping the developer debug these problems and he actually ended up compensating me for some of that work. So while my experience with the software was not so good in the end, I can only say good things about the support by the developer. It is a group of error-control protocols to achieve reliable data transmission over an unreliable source or service. He listened patiently to my problems and although he insisted that he has lots and lots of customers where the software works fine, I did manage to convince him to look at the issues I had (this is how it should be but not all developers/companies do that) and we managed to track down a couple of bugs but it seemed a neverending story and so I eventually decided to scrap syncovery and start looking anew, even though this entailed that I would probably have to pro-long my Crashplan subscription another year. ARQ is an error-control strategy used in a two-way communication system. This is when I discovered duplicati 2 and although it was still in beta, it looked very promising. Use that extra space in your existing cloud account to store your encrypted backups.In particular, I liked that it is open source and future proof in the sense that I would always be able to access my encrypted data, even in decades when duplicati may no longer be maintained. You can back up to your own Amazon Cloud Drive, Amazon Web Services, Google Cloud Storage, Google Drive, Dropbox, or OneDrive accounts, or your SFTP server or NAS. Rsync-style "rolling checksum" ensures only the changed parts of files are uploaded. Client-side de-duplication ensures Arq never uploads the same content twice. No Java means no Java-related upgrade headaches or performance problems.Īrq does all it can to minimize uploads: Compression reduces upload sizes. We often deliver patches within days or even hours of first report of a software problem.īoth Arq for Mac and Arq for Windows are native apps built for maximum device fidelity and maximum performance. We're obsessive about getting solutions to customers' problems, so we strive to fix issues in Arq quickly. Other users have also contributed Arq-compatible utilities like arqinator. We've published an open-sourcecommand-line utility so you can see for yourself your backups and directly restore your files from cloud storage. Your backups are stored in an open, documented format. All transmission over the network is through SSL/TLS. Although every precaution has been taken in the preparation of this book, The Duplicati Team assumes no responsibility for errors and omissions. Windows 7, Windows 8, Windows 8.1, Windows 10, Windows 11, Windows Server 2012, Windows Server 2016, Windows Server 2019, Windows Server 2022Īrq™ automatically backs up all your Macs and Windows PCs. Your files are stored securely, readable only by you.Īrq encrypts your file data before it leaves your computer, so your files are never sent on the network in the clear.
