![]() IDrive’s strength lies in its versatility. So really, when it makes sense to invest in these services is as soon as possible. It can also save you considerable time and money since you won’t have to rebuild your business from scratch. In short, backing your valuable business assets up with an online backup service before catastrophes happen can prevent a lot of headaches. If you’re a solopreneur building online cooking courses to sell, you could lose all your videos and teaching materials after clicking one bad link.Īn airline could experience a glitch or virus, causing computers to crash and forcing it to cancel hundreds of flights.Ī restaurant with a thriving newsletter and social media presence could lose all its customer information, forcing it to build its marketing campaign from the ground up-again. Yes, you can back your computer up onto an external hard drive, but even that drive can be ruined. If you don’t want to lose your electronic business assets to a flood, virus, fire, or theft, an online backup service is essential. When It Makes Sense to Invest In Online Backup Services Arq Backup – Best customizable online backup service.OpenDrive – Best for collaborative backups.Acronis Cyber Protect Cloud – Best for backups with an extra layer of security.Backblaze – Best for quickly backing up everything on your computer.The Best Online Backup Service Options to Consider With a free plan for solopreneurs who are just starting out and several business tiers for those who need more backup space, IDrive has what most users need from an online backup service. Full, incremental, and differential backup methods.Snapshots feature that saves up to 30 versions of each file.With IDrive, you can back up unlimited iPhone, Mac, PC, iPad, and Android devices to one account. ![]() Acronis got users complain about their download speed and I found no detail about their encryption method.IDrive has been a steady presence in the online backup market since it was founded 27 years ago, and its services have kept up with the times. And backblaze requires sending your encryption key to their server for restoring, which makes no sense to me. ![]() As for the rest, I didn't have a good time with duplicati two years ago. If I give up arq completely in the future, I'll use Duplicacy as a replacement.Ībove are what I spent time on for the last few days. But overall it works smoothly which is most important. The web-ui is a little bit glitchy, and I personally feel the settings are somehow weird. I think its idea utilising file path as a substitute to database makes the software relatively simple thus more reliable. ![]() Like tarsnap, the sorce code is available but the license is not free.ĭuplicacy starts form 2016 (according to github), records are not long but good. It supports all major platform, can send backups to S3/GDrive/ODrive/Dropbox. I basically just pay for tarsnap to say thanks to the author :) And the price is expensive (0.25$ /GB/Mon for storage, 0.25$ /GB for traffic). Tarsnap can only backup to storage provided by author (essentially S3 from amazon). I learned a lot about general backup tech by just reading the manual of tarsnap. The author really knows every detail about this backup thing and explains very well in the document. The author, the software, the documents and its business model all together is a big HARDCORE. The source code is openly available, but the license is not open-source. This comes from FreeBSD security officer Dr. Borgbase is new and designed for borg, it's easier to use with borg than rsync. rsync seems professional and doing very well to provide simple reliable storage, also have a long good track. There are some ready to use providers besides building yourself a VPS. One downside for Borg is that it requires server-side support, so you can't put your backups to S3, Dropbox or Onedrive. (This kind of check is weaker than a completely integrity verification, for the detail please read ) People are satisfied with its reliability.Īnother thing I like about Borg is, it can check CRC32 of the segment on server side and even try to repair it! This means you don't need to download everything to client, therefore very fast. ![]() And according to what I got on Google, its 10-years-long track seems pretty good. The software is open-source and well-documented. The core is written in C/Cython thus highly efficient. It works on Mac and Linux/Unix, with carefully designed encryption and deduplication. Having study this for days, and omg backup is no easy job even you're willing to pay for it. ![]()
